call_timer application
|
||||
----------------------
|
||||
|
||||
call_timer is a simple back-to-back user agent application
|
||||
that ends the call after a call timer expired.
|
||||
|
||||
If use_app_param is configured to "yes", then the call timer value
|
||||
is taken from App-Param "t" or "Timer" value. If it is set to "no"
|
||||
or that is not present, the configured default value is used.
|
||||
|
||||
The default value is configured with default_call_time config option.
|
||||
If that is not present, 1200 seconds are used.
|
||||
|
||||
Examples (ser script):
|
||||
remove_hf("P-App-Param");
|
||||
append_hf("P-App-Param: t=120\r\n");
|
||||
t_relay_to_udp("10.0.0.3","5070");
|
||||
|
||||
remove_hf("P-App-Param");
|
||||
append_hf("P-App-Param: Timer=120\r\n");
|
||||
t_relay_to_udp("10.0.0.3","5070");
