Allstream SIP configuration with Cudatel (Freeswitch)

We are attempting to setup a Cudatel PBX with Allstream's SIP and are stuck in the middle with both vendors unwilling to speak directly with each other to help in the initial SIP setup.

The only setup configuration that Allstream has provided is Signal IP:, Signal port:      UDP 5060, Media IP:, Media port: UDP 16000-32767.  And on the Cudatel side there are many configuration fields, Host, Port, Realm, Username, Auth. Username, Password, Registration.

The Cudatel PBX is at the heart a Freeswitch PBX.  What I am trying to determine is if there are more configuration settings I need from Allstream to get this box to connect or is that all normally required.  If anyone has successfully connected an Asterisk, Freeswitch or similar PBX with Allstream, it would greatly help us out.

In my experience, the guys at Barracuda Networks are really good about contacting the provider, but you generally need to contact each to give them permission to talk.

I know that where I am, it is illegal for my provider to talk to any third party until I give them permission to talk to each other. You may want to contact them and ask if there is an issue of no permission given.

Yeah the Cudatel guys have been pretty awesome in support.  We actually figured out that our Linksys router was at fault as it blocked everything even though we put the Cudatel on the DMZ.

Once we connected the WAN directly to the ADSL line, the Allstream SIP started to work right away.  The only setting they didn't tell us about was the username which was actually the DID number.  We figured it out after looking at the SIP handshakes.
