T1, T2 and T4 Timers

1. Brekeke Product Name and version:

2.4.8.6/286.3


6. Your problem:

I believe I read Brekeke SIP sets T2 and T4 timers based on T1, but I don't see where I can change T1 value?

How do I change the default value for T1?

Set the "net.sip.timer.t1" in the [Configuration] > [Advanced] page.

For example:
-------------------
net.sip.timer.t1 = 600
-------------------
Its default value is 500 (ms).


What kind of timer do you want to tune actually?

It's the INVITE I need to slow down. Our simulation has quite a bit of transport delay that we need to reproduce, however, Brekeke SIP keeps resending too quicky and often which makes troubleshooting difficult.

I needed a way to change the T1 timer to slow down the retry rates of T1, and subsequently T2 and T4, since T2 and T4 I think are values based off of T1.

I suppose the "net.sip.timer.t1" will meet your requirement.
If you use &net.sip.timer.t1 in the DeployPattern, you can define it in a certain route.
