Hi Guys,
any hints on how to change the remote SIP port for PJSIP?
My Asterisk is listening on TCP port 6533 and it seems that PJSIP is having trouble to work with it in some cases.
I can't use UDP - because of the iOS App, which requires TCP in order to run in background.
Details are below.
If you could help - it will be greatly appreciated!
Thanks,
Filip
