Point to Point SIP

Hi Aterisk Community,

I’m just starting out with asterisk but the product is looking great.

Forgive me if this is a silly question but…

I have been issued with a sip provide that is done using point to point the sip provider just authticates against our external IP and the connection only gets activated once we make a call.

I have setup the sip account information and left the username and password blank.

Is this possible to configure?

I have got a sipgate accoutn also and tested with this and ran a sip show registery and this connect fine.

On either accoutn I cannot make external calls and seem to be going round in circles.

Any help/tips greatly appreciated.
