Hello, We are having a situation where our outbound dial randomly fails (timeouts). We are using Twilio Elastix SIP for our trunks. We did not have this issue until we brought on our second and third twilio trunks online (2 more PBX servers).
I have done a pcap on one of the affected servers and it's upline firewall and also a debug on the SIP itself. Our PBXs show they are calling, but no packet is ever actually sent out. The pcap on the server and the pcap on the firewall show nothing for connections attempted out. The system will eventually give a timeout message.
After some time, and dialing or not dialing a 1 (who knows if this matters) it will eventually dial out and connect the call. It will then stay working for a little while and then quit.
At first we thought it may be UDP related, but we are using "Secured SIP" with these trunks (TCP/TLS over Port 5061).
Any suggestions on what to look for/into would be great. As a test, I fresh installed a totally vanilla server and it exhibited the same behavior.
Also, one server is behind a SonicWall SOHO and the other is behind a Meraki MX65.
