Cannot Complete Conference (ICT non-gatekeeper)

Hi All

We got two branches:

Site A is registered to CUCM 8.0.2 on HQ and have HW-CFB on site.

Site B is registered to CUCM 7.1.2 onsite and have HW-CFB as well.

We have an ICT (Non-Gatekeeper Controlled) between CUCMs.

When phone 1-A calls to phone 2-A with codec G.711u then press "confrn"

dial to Phone 1-B successfully but when press "confrn" softkey to join the calls

the phone shows "Cannot Complete Conference"

This happen only with phones on the site B reached through inter-cluster trunk

Any input will be appreciated!

Thanks both of you for your answers.

The fact is that the one branch is connected by DMVPN, and the another one is connected by MPLS.

So it was a routing problem.

When I press the conference softkey the DSP resource can't reach the IP phone.
