Hi, I'm encountering new problems on my side while answering a call from call queue. The caller still hears the on-hold music even if I answered the call from my extension. So I hear nothing, but the caller still hear music. I have this problem only with all queue. Extensions and direct number are perfectly working. Here's a part of server log : Code: 0.873 Call::RouteFailed [CM503015]: Call(2980): Attempt to reach "+33243230582"[sip:33243230582@XXX.191.94.20:5060?Replaces=OTMwMDA3ZTY0NDc0MjMyN2MxZWQ4ODFjMTliNmNmYmQ.%3Bto-tag%3Dcb0a2931%3Bfrom-tag%3D832e4c18];tag=cb0a2931 failed.
