Need help to setup with ippi.fr

[athwds]

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.
