[SIPForum-discussion] What is Session timer ?

[Stephen James]

Session timer is used as a mechanism to determine if both ends still have the 
same session state. 

Without session timer, there is no per call audit/keep alive to determine if the 
call is still up .

This is the maximum call duration without getting an acknowledgment from the far 
end. If you don't get a 200OK on the re-invite you drop the call. Otherwise you 
end up with calls not being billed properly. But first read the rfc 4028
