Without more information on what you mean by little success it's not easy
to say yes or no. These specific changes that are up for review though probably
would not help. They just improve how we handle the incoming reinvite and the subsequent
triggering of the reinvite on the other side.

If you file an issue report though I can take a look. Full sip debug of both sides would
be needed along with a udptl debug. Knowing the the firmware version and IOS version
would also be useful. The support seems to really vary between different versions...
