With the help of dialing timeout, you can limit the time between two digits while
users are typing the digits of a number through an extension. If the timeout
expires, the gateway will consider the dialing has finished and will try to send
message to SIP server. Default value is 4 seconds.
This parameter determines how long the caller party will wait for answer when
making outgoing calls through a phone.
This parameter determines how long the phone rings when there are incoming
calls

maximum time. If a phone's hook flash is pressed for a time period greater than
the set minimum time but less than the maximum time, the action is considered
as a 'hook flash' operation. If a phone's hook flash is pressed for more the set
maximum time, the action is considered as 'hang up the phone'.
