hi, i need to know how configure in Cisco Call Manager 5.1 with Siemens Hipath 4000 via SIP trunk, without using E1 QSing.

I would not recommend doing a direct SIP trunk from CM to the Hipath. You will be really limited to what you can do with it. Your best bet is to use a CUBE to interface between the two systems. However, QSIG is the recommend integration type of a Siemens PBX. Here is one document that may help.

Here is another link that may be useful.

Hi, thanks for the reply, but using E1 controller i will limited for 30 calls only, maybe 15 in / 15 out, and that's not good for me. i have more than 500 Ip phones in both sides, (Siemens and CCM).

i hope you can help me.

Thx.
