asterisk users - Apr 2018 - Explain PJSIP user matching within inbound SIP trunks

Hello,

I'm setting an Asterisk 13.14.1 box (Debian Stretch with packaged
Asterisk)  to implement SIP trunking services ie to both trunk with carrier
trunks and IPBX trunks from various brands.

For various reasons, I was inclined to implement this services with
pjsip_wizard.conf and I'm realizing I still have some remaining questions.

For the moment, letting registration questions aside, which of the
following sentences is correct for Asterisk's PJSIP stack:

1. it would identify an incoming call only looking at From header ignoring
IP settings (both IP address and port),
2. it would identify an incoming call only looking both at From header and
IP settings (both IP address and port),
3. it would identify an incoming call only looking both at IP settings,
ignoring From header for identification but using it for other things
(setting CallerID, ...).

Best regards

May I add the following to my previous question:

- When I wrote "only looking at From header", I meant looking at
domain
part of From header, leaving user part of From header for other purposes.

- With a From header such as From: "John Doe" <sip:123456789 at
foobar>, it
would match foobar with a [foobar] endpoint, and then set CALLERID(name) to
John Doe and CLAARID(num) to 123456789

It depends on configuration, but ultimately it can only be identified using a
single endpoint identifier - so not in combination, thus by From OR IP.
