Re: [reSIProcate] other unknown header field
For #1 - You should probably just configure the PJSIP client the use
STUN, then it will send it's public IP in the contact header, when it
registers.
For #2 - It would be easier for you to just use ExtentionHeaders, then
no changes to resip are required at all. BTW: I don't see anything
obvious missing from your steps below (if you are building on Windows
then the gperf steps are manual).
