Summary: [patch] chan_iax2 will create multiple sessions when
receiving retransmitted NEW
Description:
When a client initiates a call with a NEW frame, frequently the client will
send a retransmitted NEW frame prior to receiving the ACCEPT frame from
asterisk. This may result in asterisk receiving duplicate NEW frames from
the same client in short succession.
As of at least 1.4.20, asterisk will ACCEPT and create new call sessions
for both of these NEW frames originating from the same client. This results
in much protocol confusion between asterisk and the client and ultimately
leads to asterisk and/or the client terminating the call.
The correct behavior would be for asterisk to recognize second (and third
and fourth) NEW frames from the same source (socket and callno) and ignore
them.
