CUCM 9.1 Integration with Siemens HiPath 4000 Release 5.0

Dear All ,

 My customer has old IP PBX Siemens HiPath 4000 Release 5.0, and in the DR he planned to use Cisco CUCM .

We used the attached document for the integration but there is no RTP between CUCM and the PBX , any advice please ?

As in the Document , We made the MRG and made the MTP on the Voice GW but did not work .


Thanks ,

Ahmed Ellboudy  , CCIE voice 30079


Probably need more

Probably need more information. It would be great to get some debugs from the router. Basically debug ccsip messages to begin with. 

Please rate useful posts.

And also the call flow in DR

And also the call flow in DR case.

Hi there,i was making some

Hi there,

i was making some google search for some labs of my own and i found this....I see it's from 3 months ago, but maybe i can help you...I work with Siemens Hipath4000 for the last 10 years, i've seen you PDF document but it's missing "CGWB" and the "GKREG" configuration....maybe if you could provide me the "REGEN" from Hipath4000 i can lookup and see what's missing.


My best regards

Always put a CUBE between

Always put a CUBE between environments when possible unless you want to mess with making SIP Normalization scripts.  You didn't provide any CallManager traces or debugs for the call flow.


Troubleshoot like a CCIE Voice should.
