I'm sure it offers no consolation, but we have several customers (including our 
personal corporate system) using VOIP.MS.  We do not, and have never used any 
other translation than a plain port forward for inbound 5060 to translate to 
5080.

We use this same plain port forward for Voxitas (now appia) and Onecomm sip 
trunks (all of which must send the invite to port 5060).  No layer 7 needed.  
In fact anytime we have a firewall with any kind of SIP ALG (which is a layer 7 
gateway) we must disable it.

Thats not say there are not providers that couldn't be adding this additional 
port info in the SIP header.   But there are many people using a plain port 
translation with ITSP that require to send the invite to port 5060 without any 
Moh, transfer or other issues.

I'd like to see a siptrace from your trunk.  You should be able to see if they 
are specifying the port info sip header using sipviewer because sipviewer only 
shows the sip packet (layer 7 stuff) and does not show the actual TCP headers 
(layer 4) where the actual packet arrived on the port.
