What is UCM RemoteConnect?

RemoteConnect is a cloud service that allows administrators to remotely and securely access and manage their UCMs without needing elaborate firewall configurations. Additionally, it will offer end-users the ability to remotely access their UCM extensions to conduct voice/video calls or video conference/collaborations using their Web browsers (Mozilla Firefox/Google Chrome), mobile devices (iOS/Android), or other Grandstream endpoint devices (such as IP phones, video phones, etc) without worrying about NAT firewall traversal. UCM RemoteConnect is part of GDMS (Grandstream Device Management System) which runs on Amazon AWS with 99.999% reliability and virtually unlimited scalability.

 

Can I back up my UCM6300 series to GDMS if it’s connected via RemoteConnect?

Yes. Currently, UCM6300 series can back up configuration file, CDR records, recording files, voice prompt files, fax files, voicemail, queue statistics report, meeting report, IM data and Zero Config files to GDMS platform.

Can I use the UCMRC (RemoteConnect) address for endpoint registration and trunk registration?

Yes.

1. For endpoints registration using UCMRC address, please refer to the configuration guide here.

2. For UCM VoIP trunks, please configure the following settings on UCM63xx VoIP trunk:

- Type: Peer SIP Trunk.

- Provider Name: Configure a unique label to identify the trunk when listed in UCM's outbound and inbound rules.

- Host Name: Use the Trunk RemoteConnect Address + Public TLS Port value under UCM63xx webUI-> RemoteConnect->Plan page.

Note: The options below will be configured automatically on UCM after the UCM administrator enables option “RemoteConnect Mode” when creating the trunk.

- From Domain: Use the "Trunk RemoteConnect Address" listed in peer UCM63xx's webUI->RemoteConnect->Plan page.

- Transport: TLS.

- Enable Heartbeat Detection: Enabled.

- ICE Support: Enabled.

GDMS no longer detects the UCM6300 series as online after a period of time. How can I fix this?

Please check your firewall to make sure port 3478 is open, and UDP packets can be transported using port 3478 to the domain “stun1.gdms.cloud”. The GDMS platform uses UDP packets to check whether if the device is online or not.

How do I set up the UCM6300 series system for the UCM RemoteConnect service, and do I need to pay for it?

To set up your UCM6300 series system for the UCM RemoteConnect cloud service,

1. Go to https://gdms.cloud and log into your account.

2. On the upper left of GDMS platform, switch sub system to "UCMRC System" and make sure that you have selected the Organization the UCM belongs to.

3. Navigate to "UCM Device" page and click on "Add Device" button. If you have multiple UCM6300s to add to GDMS, you can also import an .xls/xlsx file with the appropriate format.

4. Enter the UCM6300’s MAC address, serial number, and its site.

5. The UCM6300 should appear online in the "UCM Device" page after a few seconds.

Users can find price and plan information for UCMRC service on our website soon. 

The UCM6300 series PBX never appeared online after it's added in GDMS. What should I do?

Please check your UCM6300 series System Settings->TR-069 page and see if "Enable TR-069" option is selected and whether https://acs.gdms.cloud is configured in the ACS URL field. Please also make sure UDP packets can be transported using port 3478 to the domain “stun1.gdms.cloud”. The GDMS platform uses UDP packets to check whether if the device is online.

What is "RemoteConnect Sessions" in the Dashboard page?

This is the number of currently ongoing calls made by RemoteConnect users.

 

 

Will disabled SIP accounts on the UCM6300 series be synced to GDMS?

If the disabled extension was synced to the GDMS platform previously, it will be removed from the GDMS platform after it is disabled on the Web UI of the UCM6300 series device.

Can I use UCM6300 series as MCU for Grandstream GVC3200 series video conferencing device to support more than 9 video feeds (max for UCM6300) during a UCM conference?

When GVC3200 video conferencing devices are used with IPVideoTalk cloud service, up to 49 video feeds can be supported. However, when used with UCM6300 series, the max video feeds supported from UCM is 9. This is because UCM6300 series video conference is different from IPVideoTalk cloud service for mixing/forwarding the video feeds. The video feeds displayed on GVC3200 series also rely on GVC3200 series model's capability of SFU/MCU support.

- UCM6300 series uses SFU (Selective Forwarding Unit) to receive and forward video streams for each video participant. The video participant device receives multiple video streams from UCM for each video feed, and needs to support SFU to decode all video streams before displaying them.

- IPVideoTalk uses MCU (Multipoint Control Unit) which mixes all video feeds into one video stream so the participants only decode one video to see all parties' video.

GVC3200/3202 currently supports MCU and can only display one video feed from the UCM, which would be the meeting host. Other participants' video feed cannot be seen. For GVC3210, SFU is supported and up to 9-way video can be displayed. Conference control is not fully supported on GVC3210 and compatibility will be improved in the future.

For video meeting, will the number of video feeds and voice codec affect the number of attendees allowed in the meeting?

Yes. Please see examples to illustrate the relationship below.

Note:

By default, UCM6300 series has “Opus Fullband (48kHz)” enabled, which will use Opus 48kHz sampling rate. If the users prefer more than 4 video feeds or more attendees in the meeting, please log in UCM6300 series web UI as admin, navigate to PBX Settings->General Settings and configure the "Meeting Voice Quality" option to “Opus Narrowband (8kHz)” instead.

For video meeting on UCM6300 series, how can we calculate the bandwidth required for each participant?

- For meeting with 4 or less video feeds:

The required bandwidth for each participant (in Mbps) = (A*1+B*0.172)*1.2+0.1

A is the number of 1080p video feeds (A = 0 or 1);

B is the number of participants excluding A. (B= Total number of participants - A);

1.2 represents the consideration of extra video bandwidth cost such as packet headers;

0.1 represents the bandwidth for audio.

- For meeting with more than 4 video feeds:

The required bandwidth for each participant (in Mbps) = X*0.172*1.2+0.1

X is the number of total participants;

1.2 represents the consideration of extra video bandwidth cost such as packet headers.

0.1 represents the bandwidth for audio.

- For meeting with screen sharing on:

The required bandwidth for each participant (in Mbps) = (X*0.172+0.512)*1.2+0.1

X is the number of total participants,

1.2 represents the consideration of extra video bandwidth cost such as packet headers.

0.1 represents the bandwidth for audio.

Note:

The above calculation applies to bandwidth required for each participant. To estimate the bandwidth required for UCM6300 series, please consider the number of participants and add them together.

For video meeting on UCM6300 series, is 1080p used for all the video feeds?

No, only one video feed can be 1080p or 720p. Also, if there are more than 4 video feeds during a meeting, or if there is screen sharing, the video bitrate for the 1080p/720p video feed will be reduced.

For video meeting on UCM6300 series, what’s the default video bitrate and frame rate?

For 1080p video: 1Mbps/15fps.

For 720p video: 512kbps/15fps.

For 360p video, 172kbps/15fps.

For screen sharing, 512kbps/5fps.

The above configurations can be modified per user’s preferences and it may impact the overall max number of allowed conference attendees depending on the trade-offs between video quality and max number of attendees.

How can I use UCM6300 series behind NAT?

- If you are using UCM RemoteConnect service, the UCM6300 series behind NAT can already work with your Grandstream end devices and Wave applications without additional NAT settings in your network routers. However, if end users are experiencing audio issues, please navigate to UCM6300 series web UI->Others Features-> RemoteConnect->Plan Settings and ensure Media NAT Traversal Service is enabled. By default, this is already enabled.

- If you are not using UCM RemoteConnect service, please try one of the two solutions:

Method 1: Configure port forwarding for your UCM. This will be limited by the NAT type of the network where the UCM and end devices are located.

Method 2: Use self-deployed or available STUN/TURN server. On UCM6300 series web UI->PBX Settings->RTP Settings, admin can manually configure ICE Support and configure STUN/TURN server settings.

Note:

Starting from UCM6300 series firmware 1.0.15.10, if both Media NAT Traversal Service and STUN/TURN server settings are enabled, the UCM6300 series will prioritze RemoteConnect's Media NAT Traversal Service.

How do I configure the audio quality of meetings?

Under the UCM6300 series web UI, navigate to PBX SettingsGeneral Settings and configure the "Meeting Voice Quality" option. If set to “Fullband Opus (48 kHz)”, 48KHz sampling rate will be used for opus codec, which should typically sound better than the “Opus Narrowband (8 kHz)” but will consume more system resources.

How many LDAP entries can the UCM6300 have in its internal memory? How many contacts can the UCM6300 return to the endpoint device per query?

UCM6300 series has no hard limit on how many LDAP contacts it can store. However, 20,000 contacts is the recommended limit as more will noticeably impact UCM web page responsiveness. When an endpoint queries contacts from UCM LDAP server, the number of returned contacts will be limited by the number of contacts supported by the endpoint.

Why can I not use my SIP extension on my deskphone, Wave web, Wave desktop and Wave mobile app at the same time?

In order to use the same SIP extension on deskphone, Wave web, Wave desktop and Wave mobile app at the same time, the SIP extension must have 3 or more concurrent registrations allowed. By default, the number of concurrent registrations is set to 3. To confirm or change this setting, please log in UCM6300 series web UI as admin, navigate to Extension/Trunk->Extensions, edit the extension option “Concurrent Registrations” to be 3 or more.

Note:

To register SIP extension on Grandstream end device, please refer to RemoteConnect endpoint configuration guide here.

Why can I not sync LDAP phonebooks between UCM6200 series/UCM6510 and UCM6300 series?

To sync LDAP phonebooks between UCM6200/6510 and UCM6300 series, the UCM6300 must use rsync as LDAP sync method. This can be configured under UCM6300 webUI->Extension/Trunk->VoIP Trunks->Edit Trunk->Advanced Settings->LDAP Sync Method.

Note: The UCM6300 may need to be rebooted after changing this setting for LDAP sync to work properly.

What are the Audio FEC and Video FEC options?

These are new options to minimize the effects of audio/video packet loss and allow the UCM6300 series to handle up to 50% packet loss for audio/video. They use the proprietary GS-FEC algorithm.

What are the Packet Loss Retransmission options?

- NACK:

By enabling negative-acknowledgement (NACK), the UCM6300 series will retransmit packets that have been lost in the initial transmission to repair the media stream.

- NACK+RTX:

It’s a mechanism based on NACK, which means it relies on RTCP packets to find out which packets are lost first. For NACK, it will retransmit based on the original packet. With RTX, a special payload is used to retransmit the packets that a NACK request indicated as lost. Retransmitted packets are sent in a different stream from the original media stream. The payload of the retransmission packet contains the payload header of the retransmission followed by the payload of the original packet. RTX retransmits using an extra ssrc, which will be marked in SDP during negotiation.

NACK+RTX can have more accurate statistics and it’s recommended for RemoteConnect users if there is packet loss during usage.

What is the ICE Support option in the UCM6300 series PBX trunk settings for?

ICE is a NAT traversal method for the UCM6300 series’ Wave WebRTC functionality and UCM6300 series SIP trunk has supported it. When using UCM6300 series SIP trunk service for Wave, if ICE Support is not enabled on UCM6300 series, you may experience audio, video and screen sharing issues.

Note:

Besides enabling ICE support on the trunk of UCM6300 series, the remote side (UCM or other trunk provider service) of the trunk needs to support ICE as well.

What is the NetEQ jitter buffer option?

Enabling NetEQ on the UCM6300 series helps reduce the effects of packet loss on audio received by the UCM.

It is a dynamic jitter buffer and error concealment algorithm used for hiding the negative effects of network jitter and packet loss. It helps keep latency as low as possible while maintaining the highest voice quality.

Note:

Enabling NetEQ will help with minimizing the effects of packet loss on audio received by the UCM6300 series. If there is packet loss in the audio sent from UCM to an endpoint, then the endpoint will need to handle it with its own packet loss mitigation implementation. NetEQ is used in WebRTC for audio QoS purposes. As such, UCM6300 series’ Grandstream Wave, which uses WebRTC, comes with NetEQ support.

What version of Asterisk does UCM6300 series run on?

The basic telephony software is based on Asterisk 16. However, a number of Grandstream’s proprietary voice/video algorithms, advanced video collaborations, device provisioning and remote management features are also integrated into the UCM6300 series.

When accessing UCM6300 series web UI via UCM’s IP address, the web browser shows the connection is not private and prevents the user from accessing it. What should I do?

This is because the UCM6300 series use self-signed certificate for web server by default. To avoid this issue, you could use UCM RemoteConnect plan for the UCM6300 series, which will provide domain name for the UCM. When users access Wave Web or admin accesses UCM Web portal, the web server will trust it and allow access.

Alternatively, you can purchase a domain name and certificate from other 3rd parties. The certificate can then be uploaded to UCM6300 series web UI->System Settings->HTTP Server->Certificate Settings page.

When I am calling another UCM extension, I hear a prompt "Please wait while I connect your call" followed by ringback tone a few seconds later. Why do I hear this prompt instead of ringback tone right away?

If the UCM extension has concurrent registration on Mobile device using Wave app, the caller will hear this prompt. This is introduced in UCM6300 series 1.0.3.x firmware for Wave app incoming call notification feature. Once your UCM account has been properly logged out from Wave app on mobile device, the caller will not hear the prompt again.

When my end devices are provisioned by UCM ZeroConfig, the config server path is not using the intended WAN/LAN IP of UCM. How can I fix this?

The UCM6300/6200/6510 series follow the rules below when providing the end devices Config server URL based on UCM WAN/LAN address.

1. UCM network interface method: Dual

1)If the end device is in the same subnet as UCM LAN 1, Zeroconfig provisioning URL will be based on UCM LAN 1 IP.

2)If the end device is in the same subnet as UCM LAN 2, Zeroconfig provisioning URL will be based on UCM LAN 2 IP.

3)If the end device IP does not appear to be in the same subnet as UCM, the IP address based on the interface selected as the Default Interface under UCM webUI->System Settings->Network Settings will be used. Example:

Default Interface: LAN 1

UCM LAN1 IP address: 192.168.129.88

UCM LAN2 IP address: 192.168.2.1

Endpoint IP: 10.16.254.68 

Zero Config provisioning URL will be based on LAN 1’s IP address.

2. UCM network interface method: Route

1) If the end device is in the same subnet as UCM LAN, for example, UCM LAN IP is 192.168.2.1, end device IP is 192.168.2.100, UCM WAN IP is 10.16.254.68:

1a) If end device IP is in UCM Zeroconfig subnet whitelist, Zeroconfig provisioning IP will be based on UCM WAN IP.

1b) If end device IP is not in UCM Zeroconfig subnet whitelist, Zeroconfig provisioning IP will be based on UCM LAN IP.

2)If the end device is in the same subnet as UCM WAN, for example, end device IP: 192.168.129.88, UCM WAN IP: 192.168.129.66 (they have the same gateway), Zeroconfig provisioning IP will be based on UCM WAN IP.

3)If the end device IP does not appear to be in the same subnet as UCM, for example, UCM WAN IP: 192.168.129.88, UCM LAN IP: 192.168.2.1, end device IP: 10.16.254.68:

3a) If end device IP is in UCM Zeroconfig subnet whitelist, Zeroconfig provisioning URL will be based on UCM WAN IP.

3b) If end device IP is not in UCM Zeroconfig subnet whitelist, Zeroconfig provisioning URL will be based on UCM LAN IP.

3. UCM network interface method: Switch

The Zeroconfig provisioning URL will be based on the UCM network interface IP address. There is only one IP address under the Switch network interface method.

When using GDS3710 with UCM63xx, upon incoming call from GDS3710 to the Grandstream end devices or Wave clients, I cannot see video preview even if the end device has already enabled Auto Preview (e.g., under GXV33xx web UI->Account Settings->Call Settings). What should I do?

Please log in UCM63xx web UI and navigate to PBX Settings->SIP Settings->Misc page, select "Enable Use of Final SDP" to ensure it's enabled. Save and apply the setting.

What's the maximum number of the External Contacts that can be added under Address Book Management on UCM6300?

For external contacts on UCM6300 address book , the maximum number is 5000.

Please note there is no limitation on external LDAP contacts.

My UCM6304A cannot be upgraded to 1.0.11.x+, how can I fix it?

If the device is on a firmware version lower than 1.0.7.x, please upgrade to 1.0.9.x first before upgrading to 1.0.13.x. Here are the links to download 1.0.9.10 firmware:

Can a meeting continue without a host?

Yes, the meeting can continue without a host. When the host chooses to leave the meeting without ending the meeting, the host will be prompt to designate a new meeting host. If the user does not designate a new host and leaves the meeting, when the user joins the meeting again, this user will still be the host.

Can I change my video resolution during video meeting using Wave Desktop, Wave Web or Wave mobile app?

Wave Desktop/Web users can change video resolution during video meeting. When the user joins the meeting from Wave Desktop/Web and turns on video, by default the video resolution is 360p. To change video resolution, the user can click on "More" options on the bottom task bar in the meeting interface, open “Resolution (SD)” setting and select 1080p, 720p or 360p. Please note that only one 1080p or 720p video feed is allowed in the video meeting. If there is already a 1080p or 720p video feed in the meeting, the user will not be allowed to change to 1080p or 720p.

For Wave mobile app, changing video resolution during meeting is currently not supported.

Can I view the existing chat history after joining a meeting from Wave application?

No, pre-existing chat history will not be available when joining a meeting. For example, a user joins a meeting after the meeting has started for 10 minutes, this user cannot view the chat history generated during the first 10 minutes in the meeting.

How can I become the meeting host when using Wave Desktop, Wave Web or Wave mobile app?

- When joining a meeting on Wave Desktop, Wave Web or Wave mobile app, the user can select the Host role and enter the meeting host code to become the host.

- If you are already in a meeting and there is no host in the meeting yet, you can click on the “Host Meeting” option and enter the host code to become moderator.

When my extension on Wave Android/IOS app receives calls from UCM call queue, it doesn't have incoming call notification sometimes. How can I solve this?

When Wave mobile app is running in background, incoming call notification is not supported if the call is from call queue. Here are the reasons:
- For call queue agents, it normally requires phone devices at fixed location. Wave mobile devices are usually not used in call queue service scenario.
- The answering time for calls from call queue is time-sensitive. Usually call queue agent has a configured period of time required to answer the call before the call goes to the next agent so that it doesn't affect the quality of service. However, the push notification time on mobile devices can vary depending on network conditions. Therefore call queue scenario is considered not applicable for Wave mobile app push notification service.
