Howdy,

Maybe the clipping of your SIP packet is occurring on another provider's
(faulty) node somewhere in between your dualing pcaps at the endpoints ?</pre>

As for what you can control, first, you might try reducing the
expiration from 3600 to 999, or maybe something in the 30-60 range is
better for you. If that works, then raise it from there, but I think an
hour is more than enough.</pre>
