I have noticed some strange behaviour when using messenger as a sip client. Messenger appears to stop transmitting RTP like some sort of voice activity detection, and some applications on asterisk also respond by ceasing/not starting RTP transmission until they get something from messenger. Milliwatt and ringback tone are examples of applications that stop sending. Voicemail appears to keep transmitting regardless of what messenger is doing. Tried using different codecs but the problem was consistent. This is my first look at messenger as a sip client, so can anyone confirm what I am seeing here is normal? Using CVS from 12/08/03 and messenger 4.7.2009. Both asterisk and messenger are in the same subnet. cheers, darren
