Connecting CM 6.0 with Siemens HiPath 4000 Release 3.0 using SIP Trunk

Unanswered Question
Dec 15th, 2007

I want to connect Cisco CM 6.0 to Siemens HiPath 4000 Release 3.0 using a SIP trunk. The Siemens HiPath got a built-in SIP trunk module and authentication is done on IP basis.

There is no problem when we are calling from Cisco to Siemens. But when calling from Siemens to Cisco, the Cisco CallManager gives a http 400 bad-request back. Maybe this is caused due to a misconfiguration on either Cisco or Siemens side.

Did someone configure Cisco CM 6.0 and Siemens HiPath 4000 using SIP trunk module? Any help will be highly appreciated.

Kind regards,


I have this problem too.

You might want to check the following document, which has configuration steps required for "

Siemens HiPath 4000 Release 5.0 using SIP trunk to Cisco Unified Communications Manager 8.5  ". Even though it is for CUCM 8.5, procedure should change a lot.

Whole lot of such documents are listed here at Cisco Interoperability Portal.

Pls rate the post if it helps.

Thanks for the info. I have already configured SIP Trunk bitween Hipath 4000 V5.0 and CUCM V7.0 through CUBE( ISR 3845), But i am not able to call both sides.

If you have any specific supported document for config. pls let me know and also let me know is their any specific CUBE IOS version required to setup this SIP Trunk solution.

Thanks in advance
