The time period you define should be less than the binding timer of the router.
33. Set the following Timers to the desired value, where required:
• SIP INVITE Timer (sec): This is the time in seconds that the phone waits for a response from the 
called party after ending 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 phone terminates the call process and gives an error 
tone to the user. The range of the SIP INVITE TIMER is 10-180 seconds. Default: 30 seconds. 
• SIP Provisional Timer (sec): This is the time in seconds that the phone waits for 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, the IP phone terminates the call 
process and gives error tone to the user. The range of SIP Provisional Timer is 10-180 seconds. 
Default: 60 seconds.
• General Request Timer (sec): This is the time in seconds for which the phone waits for response of a 
transaction request. This timer starts on initiating a transaction. This timer stops on receipt of a 
response for the request. On expiry of the timer, the phone clears the transaction. This timer is used for 
Registration request, etc. The range of the General Request Timer is 10-60 seconds. Default: 20 
seconds. 
34. To debug using Syslog Client supported by the phone, configure Debug parameters: 
•Set Enable Debug? to Yes. Default: No.
When the Debug flag is enabled, the phone will send the debug messages to the Syslog Server IP 
address. Debug report can be viewed on the Syslog Server or any other application which can capture 
the Syslog messages/debug sent by the phone. 
• Enter the IP Address of the remote Syslog Server as Syslog Server Address. 
• Enter the Server Port, i.e. the address of the Listening Port of the Syslog Server from 1024-65535. 
Default: 514. 
Syslog uses the UDP as transport protocol and listens on the port 514 (the default listening port). 
• Select Debug Levels from these options, by selecting the respective check box:
•SIP
• System
• Hardware
•Call
• Menu
• User Interface
The phone supports multiple debug levels. You may select any or all of these debug levels. The Syslog 
Client will send only the debug messages for the selected level to the remote server on the IP network. 
For example, if the debug log of 'Call's is required, you can select this option, and disable all others.
