มีหลายวิธีที่จะทำ CallBack ได้ อันนี้ก็อีกตัวอย่างหนึ่ง ผมไม่ได้ลองใช้วิธีนี้ดู
เป็นการเล่นกับ outgoing directory ซึ่งผมเคยเขียนถึงใน จะเล่นอะไรกับ /var/spool/asterisk/ ได้บ้าง
อันนี้ไปเจอมาจาก callback.agi modules (http://pastebin.ca/179670) ไม่รู้จะ credit ใคร เพราะไม่รู้ใคร post?
modules.conf
; Asterisk configuration file
;
; Module Loader configuration file
;
[modules]
autoload=yes
;
; If you want, load the GTK console right away.
; Don't load the KDE console since
; it's not as sophisticated right now.
;
noload => pbx_gtkconsole.so
;load => pbx_gtkconsole.so
noload => pbx_kdeconsole.so
;
; Intercom application is obsoleted by
; chan_oss. Don't load it.
;
noload => app_intercom.so
;
; Explicitly load the chan_modem.so early on to be sure
; it loads before any of the chan_modem_* 's afte rit
;
load => chan_modem.so
load => res_musiconhold.so
load => chan_capi.so
;
; Load either OSS or ALSA, not both
; By default, load OSS only (automatically) and do not load ALSA
;
;noload => chan_alsa.so
noload => chan_oss.so
;
; Module names listed in "global" section will have symbols globally
; exported to modules loaded after them.
;
[global]
chan_modem.so=yes
chan_capi.so=yes
callback.agi:
