--
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. Example
part of capture attached.
