i have setup s20 to facilitate calls within the offices and over WAN to connect to other yeastar PBX's. locally i can make calls , then other sites can reach the extensions registered on s20.. The S20 is behind the mikrotik router.. problem is that exten on s20 cannot call other extensions on other yeastar PBX's..
could i be missing a setting somewehere??
Hi James,
How do you connect the other PBX? by peer trunk.
You can get the pcap capture, but it is sensitive that the capture might include public IP info. You can post screenshot with mask for key info of the voip call flow.
here is the way to get pcap capture on S20:

To anaylize the call flow, you can refer the part 2 in this article:

i managed to sort the issue.. problem i have is that when i make calls , they get to extensions but either part cannot her the other.. what could be the problem??
calls from extensions get through but voice exchanges are unavailable..
I have mikrotik SIP ALG enabled and Yeastar PBX->General->SIP->NAT:
- NAT Type: Disable
- NAT Mode : No
If you disable SIP ALG on mikrotik you need to set up port forwarding on mikrotik and set
NAT Type and NAT Mode YES
James,
Did the change on the Mikrotik make a difference to the one way speech?
I am facing the same problem. PBX and phones are all behind a Mikrotik router. Phones can call each other an to the outside. There is always ringing but no voice in either direction.
