Being that VoIP devices are running over an IP network, we find that these devices become more vulnerable to attacks. Whether it be a denial of service or an attempt to use your services without you even being notified. In cases where you receive phantom calls from random extensions that do not belong to your softswitch, may point to an automated scanner, which seek out gateways in attempt to make free calls as the owners expense.
If this is occurring on your SIP Gateway, it is recommended that do not forward port 5060 on your router, but to use a unconventional SIP port.
If this is occurring on a Grandstream IP phone, users have the ability to deny calls that are not authenticated. On a GXP2130/40/60 you can find the option by navigating the the web interface, clicking on Account X-->SIP Settings-->Security Settings and enabling "Authenticate Incoming invite"
You should make sure that the phone is connected to the network and the phone is able to obtain an IP address. Secondly, check if the account is set to active by setting the “Account Active” configuration in the Account page of the Web GUI to “Yes”. Additionally, check if the login information and the SIP server are correct. If the SIP server is wrong, the phone cannot contact the SIP sever for registration. If the login information is wrong, the SIP server will reject the registration request of the phone. If all of the above are correct, there may be a problem with NAT traversal. If the GXP2130/GXP2140/GXP2160 is on a LAN and needs to register to a SIP server on a public IP, please enable NAT traversal by selecting the NAT traversal method according to your network environment. If you are unsure, it is recommended to select “Auto” to enable the automatic NAT traversal configuration feature.
