Summary:                    No hold event is generated for a second call on a
SIP channel
Description: 
The problem is easily reproducible. SIP Phone A calls SIP phone B. B
answers the call. SIP Phone C calls phone B. B puts call A on hold (event
generated) and answers C. Now phone B puts C on hold: NO hold event is
generated (hold works ok though). B can unhold/hold C as many times without
any event generated.

---------------------------------------------------------------------- 
I have uploaded a trace of the events on our system (FreePBX): Phone 305
calls phone 304, 304 holds/unholds (which can be seen in the trace), then
phone 4999 calls 304, 304 holds 305 and answers 4999, that's the last seen
event in the trace file even if 305 holds and unholds repeatedly (I have
ommited the final trace).
