I hate to be the one asking dumb questions, but I was given only 3 weeks to have asterisk ready to replace our current system, I got all working from extensions, voicemail, send and receive faxes etc…, then I read chan\_sip will be fading away and replaced by pjsip. But I cant find much documentation about pjsip. and the examples from asterisk use extensions to register phones, while the asterisk guide said to use mac addressses, I guess its really not relevant what we use…but im curious

Tks and this community is amazing

The Wiki is the place to go for information about PJSIP

[https://wiki.asterisk.org/wiki/display/AST/Configuring+res\_pjsip](https://wiki.asterisk.org/wiki/display/AST/Configuring+res_pjsip)

Especially the Migrating from SIP to PJSIP page

[https://wiki.asterisk.org/wiki/display/AST/Migrating+from+chan\_sip+to+res\_pjsip](https://wiki.asterisk.org/wiki/display/AST/Migrating+from+chan_sip+to+res_pjsip)

Endpoint names can be anything you like, It’s best practice to not have them be the same as your extensions to make it harder to brute force them.
