I just read on the Asterisk forum, that with PJSIP channel driver you can use the options “external_signaling_address” independently for each SIP peer configuration.
No does that option override the external IP address defined for pjsip and does that mean I can use “external_signaling_address” to set a different external IP address for each trunk? Set a different IP address which will be put into the SIP messages for each endpoint the trunk is registering to?
