Hi,
Kamailio doesn't delay sending of 100 trying after calling t_relay(). 
You probably have something blocking in your script: a SQL operation, a Http query or some long operation. Check your routing script for the presence of such operations.

Hi All,

 

 

 

When we are using the kamailio to handle around 70 INVITE's per second, kamailio is sending 100 Trying with the delay of around 3-4sec for few INVITE's.

 

 

 

How can I reduce the delay in 100 Trying?

 

 

 

Also, I tried increasing the number of threads for SIP routing processes. This doesnt seem to help.

 

 

 

Also tried "modparam("tm", "auto_inv_100", 0)" . This is not working.

 

 

 

Please help.

 

 

 

Thank you,

 

Vivek.
