I have Obi110 with GV on SP1.
I'd like to add ippi.fr to SP2 but cannot authenticate.
What settings must I use? Do I need to configure port forwarding on my router?
OK, I got it.
I didn't realize I had to configure SP2 service to use ITSP B -- it defaulted to ITSB A.
Otherwise the settings are just the basic SIP settings that ippi.fr provided.
