Thanks but we already tried that and still got not voice in either direction.  I was able to get a good sniffer trace over the weekend and am looking at the flow that works with our Watchguard router and comparing it to a failed flow while on the Palo Alto router.  Hopefully I can post what it ultimately took to fix this to help anyone else out.

Does anyone have a sniffer trace of a call between a VoIP on the Internet and a Mitel 5000 on an Intranet?  My customer doesn't have managed swtiches so I can't mirror/span a port to my laptop so I can get a sniffer trace.

Since neither the Palo Alto reseller, Palo Alto support, and Mitel support aren't making any progress I am going to see if I can get a sniffer trace tonight on the old router so we can "see" how it works and then compare the flow against the PA sniffer traces and figure out what needs to be adjusted on the PA.

TE,
Thanks for the reply.  I am not the Mitel 5000 vendor so I don't know about the cards installed in it, but there is only 1 private IP address assigned to the Mitel 5000, 192.168.242.30.  It is "inside" the firewall, PA-200.  Not sure about the ports, I just enabled them based on the Mitel phone vendor and it worked on the existing Watchguard Edge router/firewall.  I also got it working on a low end Cisco router/firewall.  I just can't get voice to work over the Internet using the Palo Alto 200.

MiVoice Office 250/Mitel 5000 / VoIP call connects over the Internet but no voice - Mitel 5000

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.
