Hi Better to use the L Option of the dial command
[code]L(x[:y][:z]): Limit the call to ‘x’ ms, warning when ‘y’ ms are left, repeated every ‘z’ ms) Only ‘x’ is required, ‘y’ and ‘z’ are optional. Numbers must be integers- beware of AGI scripts that may return long integers in scientific notation (esp PHP 5.2.5&6) The following special variables are optional for limit calls: (pasted from app_dial.c)
LIMIT_PLAYAUDIO_CALLER - yes|no (default yes) - Play sounds to the caller.
LIMIT_PLAYAUDIO_CALLEE - yes|no - Play sounds to the callee.
LIMIT_TIMEOUT_FILE - File to play when time is up.
LIMIT_CONNECT_FILE - File to play when call begins.
LIMIT_WARNING_FILE - File to play as warning if 'y' is defined. If LIMIT_WARNING_FILE is not defined, then the default behaviour is to announce ("You have [XX minutes] YY seconds").[/code]
