I have Lync deployed with a trial SIP trunk with 20 DID numbers. We have an existing Mitel phone system that is not tied into Lync and there is no plans for this. I was thinking i could forward the 20 pilot users Mitel phones to their new Lync pilot DID numbers so that they would not need to inform everyone of their trial number. I was wondering how I could configure Lync so that when they dial out with Lync their Mitel number shos as the caller ID.
Thanks
