How to adjust timings for Callback extensions ​

WARNING

Applies to VoipNow 3 and higher!

In order to adjust timings for callback extensions you need to set three global variables in the dialplan. This articles explains how to do that.

Step-by-step guide ​

  • STEP 1: Connect to your VoipNow  server as root using a SSH client (e.g. Putty).

  • STEP 2: Open the /etc/asterisk/extensions.conf file in an editor and add the statements below at the beginning of the file, in the [globals] section:

    • CCBPASSTIMEOUT= <CCBPASSTIMEOUT_value> | Set the number of seconds the extension will wait after the final digit when typing a password. The default value is 6.
    • CCBNUMBERTIMEOUT= <CCBNUMBERTIMEOUT_value> | Set the number of seconds the extension will wait after the final digit when typing a number. The default value is 6.
    • CCBDIGITFIRSTTIMEOUT=<CCBDIGITFIRSTTIMEOUT_value> | Set the number of seconds the extension will wait before entering the first digit. The default value is 6.
