When context id is reused by another termination, initial packet containing $ (=choose one) is not added to context but belongs to context 0xfffffffe(context id value used in wireshark for choose one). This affects context listing in MEGACO packet contents and Telephony->Voip Calls listings for MEGACO. https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=6311 svn path=/trunk/; revision=38910
