[SIPForum-discussion] min-se and session expires timer

[Chittaranjan Panda]

Karthik,

Min-se is the minimum value of timer , when UAS / UAC needs a session refresher.

For ex:

Let's UAS has configured Min-Se as 200 sec. UAC sends an INVITE with session-expire with Value less than 200 sec (ex 100 sec).

Then UAS sends 422 interval too small with Min-se value 200.

So that UAC will aware of the minimum session refreshment required for UAS.

It needs because UAS should not overload with lots of session refreshment ( Re-INVITES and UPDATES) for a single dialog.

You can increase the min-se value with both party agreement.

hi All,

1. What is the true meaning of min-se and session expires timer?

2. Is it legal to increase the min-se timer or session expires timer higher than the default of 1800 sec?

Thanks
