Why am I receiving calls from unknown internal numbers, and how can I prevent these calls?

Since VoIP devices operate over an IP network, they are more susceptible to attacks. Whether it’s denial of service or attempts to use your services without permission. Calls from random internal lines that do not belong to your software keys could indicate an automatic scanner attempting to call gateway devices to make free calls charged to their owners. If this happens on your SIP Gateway, it is recommended to avoid forwarding port 5060, use an uncommon SIP port, or implement security measures on the SIP server side.

If this is happening on a Grandstream IP phone, users can reject calls from unauthenticated sources. For example, on GXP2130/40/60, go to the web interface, navigate to Account X -> SIP Settings -> Security Settings, and enable “Verify incoming invite” to reject unauthenticated calls.

Why can’t my GXP2130/GXP2140/GXP2160 device register to the SIP server?

First, ensure that the phone is connected to the network and has received an IP address. Then, check if the “Account Active” configuration in the Web GUI under Account Settings is set to “Yes”. Also, verify that the login credentials and SIP server details are correct. If the SIP server is incorrect, the phone can’t communicate for registration. If the login credentials are incorrect, the SIP server will reject the registration request. If all the above is correct, there might be a NAT traversal issue. If your GXP2130/GXP2140/GXP2160 is on a LAN and needs to register to a SIP server on a public IP, make sure to enable NAT traversal according to your network environment. If unsure, it’s recommended to enable the automatic NAT traversal feature by selecting “Auto”.
