Hi All,

 

I am after some assistance troubleshooting incoming one way audio with remote extensions.  

I have a remote office with the handsets registering over the internet back to the pbx

 

Outgoing calls over SIP work without issue.

 

I have the correct ports forwarded for SIP and RTP, however I am experiencing one way audio on the calls.

 

Where should I start troubleshooting the issue? Is STUN required?

 

Any help would be much appreciated.

 

 

Thanks, Jackson Fisher
