; AstroCom SIP Bridge — PJSIP Configuration (chan_pjsip)
; /etc/asterisk/pjsip.conf
;
; Downstream PBXes REGISTER to this server.
; Each bridge requires three stanzas sharing the same base name:
;
;   [bridgeN-pbx]       type=endpoint  — codecs, context, links to auth/aor
;   [bridgeN-pbx]       type=aor       — stores the registered contact URI
;   [bridgeN-pbx-auth]  type=auth      — username / password the PBX uses
;
; The PBX must be configured to register with:
;   Registrar : sip:<this server's IP>:5060
;   Username  : bridgeN-pbx  (must match auth.username below)
;   Password  : the 'password' value in [bridgeN-pbx-auth]
;
; Outbound calls to this PBX from the dialplan:
;   Dial(PJSIP/${EXTEN}@bridgeN-pbx)
;   Asterisk substitutes the registered contact URI automatically.
;
; Disable/remove sip.conf (or set chan_sip bindport=0) so both
; modules do not compete for port 5060.
