MeetMe: "That is not a valid conference number."

Ensure your meetme.conf file uses "," commas and not "|" pipes.


conf => 1995,1234

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 =>
;noload =>

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:

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

Unable to connect to remote asterisk (does /var/run/asterisk.ctl exist?)

Check to ensure that the user you are attempting to connect as has full rights to /var/run/asterisk.

Change /etc/asterisk.conf:

astrundir => /var/run


astrundir => /var/run/asterisk
