Hi Everyone,
I have managed to setup a trunk between our 3300ICP system (V4.1 SP1 with 2 SIP trunk licences) and an Asterisk server on the same LAN, and by all accounts things are working well in both directions BUT audio does not work from my desk phone to/from the endpoints on the Asterisk server. Calls to/from any other combination of Mitel/Asterisk endpoints (including tablets connected to the Asterisk system via wifi) work fine - it's just my desk phone that won't play nice.
My phone is a 5235 connected to the 3300 and calls to/from another extension with a 5235 to the Asterisk world work fine. All the phones connected to the 3300 are using the Minet protocol.
At face value, this seems to be a CODEC or RTP port-type issue, but there's not much that can be adjusted within the 3300 that will tweak my phone and as far as I can see, the setup of my 5235 is identical to that for the working one. Staring at packet traces and SIP logs on a Snom phone (on Asterisk) hasn't been enlightening either!?
Any practical suggestions?
Thanks
