SIP Trunk between CUCM 7.x and CCCM 5.x

[abraham23482]

Hi

Is it possible to create a SIP Trunk ( Not ICT) between 2 Call manager servers present in 2 different networks with routing enabled between them. If Yes,

could someone help with its configuration.

Thanks in Advance

Hello,

Yes. Here you can find General Deployment Considerations for SIP Trunks:

Here you can find information for configuration:

Why you want to use SIP?. ICT H.323 is the simplest way to communicate CM clusters.

Hope it helps, if it does please rate.

Kind regards,

- Adrian.

I agree with Adrian, while it's technically possible to create a SIP trunk between 2 CUCMs, the highest level of compatibility and features is achieved by using an ICT non-GK controlled

Any particular reason to do SIP over an ICT?

Hi Abrahm

I recommend you that use the ICT (non-gatekeepr), for this conecction between this CM,

go to Gateway/Trunk/ICT,
