MiVoice Office 250/Mitel 5000 / VoIP call connects over the Internet but no voice - Mitel 5000
« on: January 22, 2015, 02:34:18 PM »
We are changing from one WAN router to another, a Palo Alto PA-200. I have configured all the port forwarding from the old router to the new PA-200, but when I try a VoIP call to a VoIP phone on the Internet the call connects but I get no voice in either direction. Here are the port forwards:
UDP 6004-6261
UDP 50098-50508
UDP 20001
UDP 1118
TCP 3998-3999
UDP 5060
TCP 6800-6802
TCP 44000
TCP 4000
The above settings work without issue on the old router, but not on the PA-200. My Mitel vendor tells me UDP 50098 - 50508 are used for the voice traffic. I see with a sniffer trace UDP 50102 between the Mitel 5000 and the Internet based phone, but really no problems. Any ideas on what further PA-200 router config changes might be needed to get this working? Or any ideas on how to troubleshoot further? I have been looking for a Mitel VoIP packet flow but haven't been able to find one. I do see the call connecting on TCP 6800 and then another TCP 3999 and suspect these are just part of the call setup flow.
