Hi,

I'm playing around with SIP trunking between our Mitel 3300ICP and an Asterisk (Trixbox) machine.

I have it working one way:

Asterisk -> Mitel is no problem
I can dial all Mitel ext, and even out over the ISDN BRI in the Mitel.

The other way around (Mitel -> Asterisk) is a problem though. Can't get the Mitel to use the Asterisk box as an Registrar.

Annyone else goofing around with this??

Mitel 3300ICP is running R7.0 UR2 and the Asterisk is a Trixbox machine ver 1.2.9.1

Using a Mitel 5220 in SIP mode and a Nokia E-70 connected to the Asterisk Box.

Any input on the subject is welcome.
