[asterisk-bugs] Please Re-Open ASTERISK-16912

[Karsten Wemheuer]

Hi,

I hope this is the right way to contact a bug marshal.

The issue ASTERISK-16912 has been closed in JIRA, but I am thinking, it
is still a bug and should be reopened.

I contacted vendor Aastra a few days ago, and they told me, that the
phone behaves correctly. They found out, that asterisk is sending two
re-invites in a short time frame and without waiting for an response of
the phone. According to RFCs the phone can respond with "500" and a
"Retry Later"-Header. 

So I think, asterisk should wait with the second re-invite or should act
upon the 500 with "retry later" in a way, that not terminates the call.

If You take a look at attachment "issue-18254_directmedia.txt", You'll
see in line 4364 the first INVITE sent to 192.168.10.202.
In line 4456 there is the second INVITE sent to the same phone. There
are no responses from the phone in between.
In line 4935 the 500 Error is received by asterisk.

Thanks,

Karsten
