VoIP Phones - Asterisk: Difference between revisions

Line 9:

Asterisk has two methods to configure SIP connections. The legacy "sip.conf" (SIP) and the more modern "pjsip.conf" (PJSIP).

Newer installations of Asterisk should be configured to use PJSIP as it will be more supported as Asterisk development continues. It ~~isn~~'t a ~~good~~ ~~idea~~ to ~~have~~ an ~~installation~~ ~~that~~ ~~mixes~~ sip.conf ~~with~~ pjsip.~~conf~~.

Newer installations of Asterisk should be configured to use PJSIP as it will be more supported as Asterisk development continues, '''however''' it's been reported that PJSIP doesn't support in-band DTMF detection properly. You may need to switch back to legacy sip.conf if this affects you. The official recommendation on the [https://trac.pjsip.org/repos/wiki/FAQ#dtmf PJSIP FAQ] seems to be to write your own plugin if you need it. In-band DTMF support seems like an important thing to have, so we suggest raising a bug to report a missing feature in PJSIP if this affects you!

It isn't a good idea to have an installation that mixes sip.conf with pjsip.conf.

When reading the instructions below be aware which are for sip.conf and which are for pjsip.conf. PJSIP examples are below the SIP examples on this page.
