UPDATE - I have the gateway 1 ( 1#) getting a dial tone and can dial through to my SIP provider.
Can Gateway 0 (0#) be enabled to dial PSTN.. and good to have a dial tone on the as well as before?. This is the important one will be using frequently.
I love to explore the Dial plans, unfortunately this is locked for obvious security reasons.
I've also noticed the soft boot of the SPA did not pick up the new config, hard boot did the trick.
