Asterisk support natively the Call Path Optimization if using IAX2 protocol.
In this way Asterisk allows two endpoint to exchange their signalling/media directly.
I would like to make the same thing in SIP, but I found no way to do it via sip.conf or extensions.conf .
Is there a way to do it?
If it is not allowed Asterisk developpers should think to implement it.
Any opinion about this matter would be appreciated,
thank you very much in advance for your attention,
