We have CUCM 6.1 and have few remote sites that are connected via point to point, MPLS and in network but in different building.
What would be the best solution for this, we do not plan to install a router in every site. We are looking as one solution for all. I remember in Nortel pbx that we can have e911 server that contain the addresses for every phone number/DID that we have.
Is the any inexpensive solution for this issue?
Your input is much appreciated.
