<p class="MsoNormal"><span style="color:black">I have an integration between CIC and CUCM. All works fine, but when calls are made from CIC to a Cisco IP Phone, the IP phone rings. When answered, there is nothing. You end the call and the IP Phone rings again.
Again there is no RTP. Only on the 3<sup>rd</sup> time this happens is the call successful. I have 3 sites configured like this and it is working correctly only on one and according to me the configuration is identical on all 3.<o:p></o:p></span></p>
