Cisco call manager 9.1 integration with siemens hipath 4000 EPABX

Dear all,

Hope you all are doing well !! :) :)

We are planning to integrate our CUCM 9.1 with siemens hipath 4000 EPABX I would like to know this compatible?

2.If we are creating a trunk will it be SIP or QSIG?

3.Do we require any special Licenses for such integration?

4.Do we require to do any changes in the EPABX system we are using cisco 2901 Voice supported router which has E1 card insrtalled.

5.can we keep half analog phones and half IP phones to make to work to make PSTN calls? or do we have to completly migrate all Analog phones to IP base




I'm not familiar with Siemens

I'm not familiar with Siemens but to answer you're question.

1.It would appear so as a search on the internet revealed integration documents for sip with Callmanager 7.1

2.See answer 1 .SIP


4.Not sure about the 4000 but if you're using SIP then you won't need the 2901 and E1 card

5.By analogue phones do you mean cisco or Hipath.Either way i can't see it making any difference.

Could you please clear my doubts on this?

Dear Ajith,If it has been

Dear Ajith,

If it has been said that this setup is not tested, that alone should indicate that the setup won't be supported by TAC. TAC will only support setup that has been documented. Beyond the documentation, the setup may/may not work, but you won't be able to avail support on it.
