iPhone connection to FreePBX

Hi

I am trying to configure an Apple iPhone to our FreePBX system.

  1. When I go to SIP Accounts, I select Other SIP Provider. I enter parameters, but I do not know what lines up to the various SIP Extensions in FreePBX.

Can the Domain name be my FreePBX IP address (perhaps followed by :5060) ??

  1. When I save the parameters, it does not seem to save them. Well I do not have another SIP provider added.

Any tips?
