Mitel MiVoice Business/MCD/3300 / Asterisk-3300 SIP call issues
« on: April 26, 2017, 03:11:33 PM »
I've recently started with a software company and had a 3300 ICP dumped on my lap to get set up/configured so that our developers could write a software interface that will allow our main software product to communicate with Mitel phone systems (via OIG).

We've got most things set up and going, but in testing we're having issues getting calls passed from an Asterisk phone system into  the Mitel system. I'm sure it's something I've missed in SIP configuration, but I don't know what.

The software log file on the phone system is showing the following:

Refused to deliver a event[ServiceFailNotification; 5] without a valid session id


The two systems are connecting, because I can also see:

SIP trunk Aster.42 Account 150 Registrar 192.168.1.42 has registered successfully. The registration will expire in 3600 seconds.


What am I missing to get calls to come in? What needs changed to provide a session id - something on Mitel, or on Asterisk?

Thanks in advance for your time/help/patience.
