[Freeswitch-users] Inbound calls one way audio remote handsets

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.
