I have a customer that has CUCM and CER, but they are also doing Microsoft Lync SIP Phones in a number of locations on the same site. Lync is connected to CUCM via a SIP trunk. I am wondering what (if any) possibilities there are to route accurately 911 calls from Lync phones via the appropriate ERL through CER.
CUCM 7.1.5 upgrading to 9.1
CER 7.1 upgrading to 9.1
Thanks in advance for your assistance.
No, this is not possible as Lync will not be discovered by CER as it is not registered to CUCM, nor using CDP. I don't think subnet based tracking would work either.
