We have integrated via an intercluster trunk (Non-Gatekeeper Controlled) our CCM [4.1(3)sr2] with a CME, but we have one problem, when I make a call from CCM there is not the dial tone (even if the remote phone is ringing).
If a phone registrated on CME call a phone registrated on CCM there is not this problem.
When the two phone are conneted there are no problem of comunication.
I had the exact issue, but since both the CME router and the CCM server belonged to the same company I decided to reconfigure the CME as a SRST and the now CCM-registered phones did not have this signalling issue.
