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

Can you please provide "core show locks" output for this issue?

Build Asterisk with DEBUG_THREADS enabled.  Then, when it locks up, grab
the output of the "core show locks" CLI command.  That should tell us where
it has locked up.
