Summary:                    1.6.2.0_beta3 locks up in certain SIP scenario
Description: 
Hi!

In this scenario 1.6.2.0-beta3 locks up:

--INVITE-->
<-407------
[ACK is lost]

--INVITE w/credentials-->

As soon as the second INVITE is received, chan_sip does not do anything
anymore. I see SIP packets sent to asterisk but they do not show in in the
log anymore.

If I make a call from dahdi to SIP I see that chan_sip sends out the
INVITE request, but the incoming SIP requests are not processes by
chan_sip.

I tested the above scenario and this beahvior is only in 1.6.2.0-beta3.
Asterisk 1.4.25 and svn-trunk r201907 behave different, see

Thanks for the information.  The problem here is an infinite loop in SDP
parsing which has already been fixed.  Specifically, it was fixed in
revision 202340 in the 1.6.2 branch.

1.6.2.0-beta3 has the bug.  1.6.2.0-beta4 has the fix.
