RE: MITEL 3300 SIP TRUNK TO OCS 2007 communication ?



Has anyone managed to get calls working between their Mitel 3300ICP and Office Communications Server 2007?



I have got as far as the call being passed all the way from Office Communicator 2007 via the OCS server... via an OCS Mediation Server to the Mitel ICP Controller but always get "SIP/2.0 404 Not Found" back from the controller's IP Address (i'm using Ethereal)



If anyone's trying to do the same and wants to know what i've done i'm more than happy to compare notes.



There must be a genius out there somewhere who can help me :-) ...please!



Thanks v much



T
404 not found normally indicates that the issuing device does not know how to get to the TO device from the INVITE message. I'd start by looking at the programming for typos and case related issues.

Does anyone know what the TO: URI should look like "going up" a Mitel SIP Trunk?
