Hello everyone - have a super strange issue occurring at a few offices that I support. Users are able to receive inbound calls without any issues but are having some outbound call issues. When they place calls outbound they are able to hear the ring-back tone however, when the person on the other end answer the phone they can’t hear them. It’s just silence. I had the users reboot phones and I also rebooted the PBX but that didn’t resolve the issues. I didn’t make any changes on our Firewall or PBX so I figured it was only right to raise a trouble ticket with Vitelity.
Vitelity said and I quote “Our dev team migrated our outbound servers to our new platform last night, which utilizes a new RTP port range of 16384 to 36385 UDP”.
I logged into our firewall and saw that we had previously whitelisted RTP ports 10,000 to 20,000 so I changed the port range to what Vitelity specified but the issue persists. I’m posting here as I am hoping someone else on this forum has Vitelity and might also be experiencing this same issue. Any help would be greatly appreciated.
