We will have 2 CCM (Primary and secondary), 4 3640 with Dual-Port 48 Channel T1 Voice/Fax Network Module in different 4 locations. The company will have T1-PRI line after taking away their PBX. So, the end-user will call on-net (4 digits) and off-net (dial 9).
The only I confuse now is that how do I register 3640 to CallManager (use MGCP or H.323 gateway)???? Is there any different configuration on 3640 for MGCP or H.323??? Any document I can read?? Any people can share how to configure 3640 with T1-PRI??
Regarding H323/MGCP and 3640 registering to CallManager:
1. In case of H323, 3640 and call manager have a peer-to-peer connectivity and 3640 does *not* register to call manager, only IP phones register to call manager.
2. In case of MGCP, the Call manager is your call agent which is the centralized call-flow/call-directing box so 3640 will in this case register to call manager.
Configuration of Voice T1 PRI on NM-HDV/MFT T1 cards of a 3640 is very similar to other PRI configurations. Below is a sample config. You need to find out your switch-type, and it has to match your PBX/CO, same for framing/linecoding and clocking. Also below are some URLs regarding the subjects of your interest.
WARNING ... there is a (little) known bug in 12.2.2XN on a 3640 with the NM-HDV module which will cause a DSP to "go bad", i.e. fail the "test dsp" command ... the result is a one-way audio call on the call that passes through this DSP ... this problem mainfests itself typically in the first call made ... weird, though, "show voice dsp" shows the DSP is idle, thus OK ... that one got me ... anyway, the solution was H.323 for this client, and I am watching that bug, which, believe it or not, is not tracked on the 12.2.2XN code set ... another hmmmm ... HTH!
