It's not my goal this time, but good question. When a global timeout is
reached and jumps to the T extension, can I change the timeout
(Set(TIMEOUT(absolute) again) and go back somehow?
When we dialing this isn't a problem use L option.
# 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.
The following special variables are optional for limit calls: (pasted
* LIMIT_PLAYAUDIO_CALLER - yes|no (default yes) - Play sounds to
* 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").
