Asterisk#
Use Asterisk with DIDWW SIP Trunking to build a self-managed IP PBX that routes inbound and outbound calls through Asterisk.
Route incoming calls from DIDWW numbers to Asterisk.
Deliver calls to internal SIP endpoints through the Asterisk dialplan.
Use DIDWW numbers with Static Endpoint or Dynamic Registration trunks.
Place outbound calls through DIDWW Outbound Trunks.
Configure SIP signaling and media with Asterisk PJSIP.
Use existing DIDWW phone numbers for inbound and outbound calling.
Note
Choose the guide that matches the SIP channel driver used by the Asterisk installation. Use Asterisk PJSIP Configuration (v20–23) for Asterisk 21 and later. For Asterisk 20, use the PJSIP configuration unless the installation is explicitly configured with
chan_sipandsip.conf.Asterisk deprecated
chan_sipin version 17, stopped including it in default builds in version 19, and removed it entirely in version 21.
Configure inbound and outbound calling for Asterisk v20-23 using chan_pjsip and pjsip.conf.
Use the preserved configuration for Asterisk v20 or earlier only when
the installation still uses chan_sip and sip.conf.
