Summary: Asterisk hangup calls if two identical invites are
received
Description:
Context:
Asterisk server receiving incoming SIP calls from a PortaSIP softswitch
Problem:
Sometimes the softswitch sends two identical INVITES in a row as if the
first OK from Asterisk was lost. When this happens Asterisk keeps resending
the 200 OK message although it in fact receives the PortaSIP ACKs and the
debug shows that it supposedly stopped retransmitting the 200 OK packet.
Then, after 6 retransmissions of the OK packet (all of them ACK'd by the
remote party) Asterisk hangs up a perfectly valid and working call.
The call works fine if there is no retransmission of the first INVITE
packet.
Debug:
I'll attach two log files with verbose and debug enabled. Also SIP debug
was active. One of them shows a valid call and the other shows the problem
I described above.
