Configure p2p in sip calling

Asterisk Asterisk Support

Hello,

To call on any number through sip calling I have written this line in extensions.conf

I don’t know much about asterisk and I think if I go with this way then it is not peer to peer calling. How to configure peer to peer calling for any mobile number ?

What does Macro-sipanswer do?

What do you mean by peer to peer calling?

Guessing, you may want the transfer application. This is somewhat fragile and may not be supported by any ITSP involved.
