Hi all, we have a customer who has expressed interest to gradually migrate from their existing Mitel solution to a Cisco communications manager solution. They plan to have both environments live with a SIP trunk for communication between the systems. As the mitel phones go bad (or budget comes available) they will buy cisco phones and move the extensions over, until everything is on cisco. We currently have the SIP trunk setup and working between the Mitel and Cisco for our proof of concept.
The extensions on the Mitel systems are a jumbled mess, meaning every time we move a single phone we need to create a new ARS Digits Dialed route pattern as an exact match (as apposed to a block of extensions) to point it to the new cisco system. This customer has about 1000 endpoints spread accross two Mitel servers (their version is below). Are there any limitations on the Mitel side that would prevent us from doing this process?
