Configure the following SIP message related timers:
• Set the SIP INVITE Timer . This is the time in seconds that NAVAN waits for a response from the called
party after ending the INVITE message. This timer starts after sending INVITE message to the called party
and stops on receipt of the provisional response or the final response or when the user disconnects the
call. On expiry of the timer, the call process is terminated by the NAVAN and an error tone is played to the
user. The range of the SIP Invite Timer is 10-180 seconds. Default: 30 seconds.
• Set the SIP Provisional Timer . This is the time in seconds that the NAVAN waits for the final response
after receiving the provisional response from the called party. This timer starts on the receipt of the
provisional response from the called party and stops on receipt of the final response from the called party
or when the user disconnects the call. On expiry of the timer, NAVAN terminates the call process and plays
error tone to the user. The range of SIP provisional Timer is 10-180 seconds. Default: 60 seconds.
• Set the General Request Timer to the desired duration. This is the time in seconds for which NAVAN
