Hello
I am having an issue with our IP phone system where it is getting one way audio, the client can’t hear us when we call, if the call is placed right away it will work just fine.
the setup
Freepbx server > VNP > site A
Freepbx server > VNP > site B
Freepbx server > VNP > site C
Freepbx server > VNP > site D
router: Edgerouter POE5
FreePBX 13.0.192.16I am at a lost, I have contacted our SIP provider, but they can’t help right away because they need to check with their media peer.
The issue has been happening for a few months as far as I can recall, at first I didn’t think it was our system, but once I started doing recording of the calls it was clear that the issue is with our system and not with bad cell call or something like that on the clients end.
I have provided our SIP provider with tcpdump and wav files already, just waiting now on them to find out what’s going on, been a couple of weeks already.
Anyone experienced this, wonder if this is an issue with my setup or SIP provider? What could be causing one way audio, always happends on outgoing call and client can’t hear.
Please help. thank you
