Cisco Callmanager Integration with tother PBXs

Dear all

I have a project, which is integrating Cisco call manager PBX with the following PBXs

1. Siemens HiPath 4000 Ver 2.0

2. Avaya S8400 Communication Manager version 5

3. ALCATEL 4400 WM1, The CPU is CPU3 with software version R3.2

4.SIEMENS ATEA, OMNI-230,Version X185

5.SIEMENS, HICOM 300E, software version1.

6. NORTEL NETWORKS, OPTION 61C, X11(SOFTWARE Version)

all of them in remote sites except the first two pbx (hipath and avaya) they are localted in the same datacenter of the cisco call manager.

I need your recommendation. for which one should I go for SIP? QSIG with E1?

I need your advice in this and if there is a useful documents, I checked in cisco they have.

but i am tryin got find a way to connect them through SIP using IP, not using E1 line.

for sure i will use E1 line if it is the last option i have

thanks in advance

Re: Cisco Callmanager Integration with tother PBXs

All depends by the support you have on the PBXs. If it is good, you would try using IP.

If not, E1 is better because you can hook a router between PBX and PSTN, and route without ti ewven know there is a router.

In any case, you will also need to hire a reputable professional for the job. If you do not have voice experience and try that yourself, it will be source of much frustraion and anger customers.
