Troubleshooting Remote SIP Connections
Things to check if a remote phone or SIP Provider is not working. This can no audio, one way audio, poor audio quality, dropped calls, or other intermittent behavior.
When an issue is reported, we advise to start by ensuring the following settings are correct:
- External IP or External Host are properly set in PBXSetup=>SIP
- Extension is configured as a WAN phone (Under advanced in Edit Extension page).
- ACL under Networking->Access Control->Access Control List make sure that the Remote IP address isn't being blocked.
- The appropriate port forwards are configured in the Main Site Router Port Forwarding
If you are troubleshooting a remote phone and you have a network available that you are certain works for registering remote phones to other systems, this network would be a good place to attempt to register the remote phone from. If it works, then the problem is most likely with the Remote Site Router as opposed to the router in front of the PBX. If it doesn't work then it's most likely an issue with the Main Site Router or and ACL issue.
If you are troubleshooting a SIP Provider, try registering a remote phone from your office and ensure that it works. This will help to discern that everything we expect to work with regards to the Main Site Router and PBX settings are correct.
A great resource for checking the SIP compatibility of a router, as well as instructions for changes that may need to be done on the router such as disabling ALG or SPI.
