Summary:                    Maximum retries for seqno 102 when re-inviting.
Description: 
We have a provider with two softswitches. Number one which contacts us, and
number two which goes via number one to us.

If a call comes through from the first softswitch (directly from number
one to us), a call gets setup properly and we have a proper working RTP
stream.

If a call comes through from the second softswitch (going through the
first one, and then to us), the call gets setup, we hear one second of the
RTP stream and then the call drops out.

I will attach a file with the output of "sip debug"

- softswitch-two.txt (not working)

At line 366, you see a re-invite with CSeq 102. And then retransmits of
them in a fast tempo till asterisk gives up.

I personally think that it shouldn't be 102 because 103 has already been
shown.

This seems similar to issue http://bugs.digium.com/view.php?id=10274, except
there's no T.38 involved here.
In that issue, there were two Asterisk boxes in between two ATA's and they
exhibited the same behavior on re-invites.

Are both Asterisk boxes running 1.4 with an SVN checkout later than
revision 77824? If softswitch-one is not, then it is not sending the 100
Trying message it should be sending to softswitch-two which is why it
continues retransmitting the re-invites.
