I am interested in getting into the voice over ip arena and the first things I wanted to learn about are integration. Currently I have a nortel MICS with and E&M card and a cisco 2610 with and E&M card. That being said, is this the right way to integrate the older voice systems with the newer voip systems?
What other methods can you use to connect existing Key or PBX systems to a VOIP gateway like the 2610 with cards? Can you do it with ISDN, or T1? I am not really familiar with the concept of trunking or networking the older telephone systems with the new ones.
Any resources you can suggest for integration would be greatly appreciated.
I am also looking for some good training materials on the Norstar MICS and the Nortel Meridian Phone Systems, since the majority of the integration projects we will be doing will involve these telelphone systems.
