| Hey stumbled on your post while searching for something else related to Ocs and Mitel. Anyway just thought I'd note that from my experience the "SIP/2.0 404 Not Found" error you receive when trying to call from communicator to a phone on the mitel system is normally a result of not having correctly configured your SIP Peer profile assignment by incoming DID form on your 3300. You need to associate the incoming DID numbers on your mitel system with the SIP trunk connected to your OCS. For example if your extension range on the Mitel system is 200-300 you need to assign this range to the SIP trunk connected to OCS so your 3300 knows to accept incoming calls for these numbers on that sip trunk. Do the same for external numbers you want to be able to call out to from OCS. Hope that helps. |
