MITEL 3300 and Nortel/Avaya CS1000E - SIP connectivity
« on: December 28, 2011, 08:17:23 PM »
Has anyone ever set up SIP trunks between MITEL 3300 and Nortel/Avaya CS1000E?

I can call from MITEL to Nortel phone but not from Nortel to MITEL. MITEL returns the error 404 (not found message) to CS1000E.

Thanks in advance for the help.

If I had to guess its because the nortel sends the phone context string in the SIP URI phone-context=cdp.udp and the Mitel doesnt know what to do with it.
