Introduction

Asterisk is an open source PBX system then runs on the Linux operating system.

I support Asterisk because of its price benefits and ease of expansion.

Some key features of Asterisk are listed below.

  • Voicemail to eMail
  • Softphone (Computer Based Phone) support
  • Analog Phone Support (PSTN)
  • ISDN PRI support for DID based routing

FAQs

How do I use "Console commands" (transfer, dial, answer, hangup) from the cli?

You'll need chan_oss for that. Chan_oss connects the sound card to the outgoing line. By default it is disabled to include the module chan_oss, you will need to edit a section of the modules.conf file to match the sample below:

; 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

I configured a new IVR and clicked the check box that states "Enable Directory". When I call in and type # I get "I'm sorry, that's not a valid extension." What did I do wrong?

You must install Information Services, It provides a number of applications accessible by feature codes:

  • Company directory
  • Call Trace (last call information)
  • Echo Test
  • Speaking Clock
  • Speak Current Extension Number

How do I enable Attended Transfer?

Update your features.conf file to reflect the settings below:

[featuremap]
blindxfer => #                  ; Blind Transfer
disconnect => *9                ; Disconnect Call
automon => *0                   ; One Touch Record
atxfer => *                     ; Attended Xfer
