[OpenSIPS-Users] delay 200 OK in opensips for pre-configured interval

[Bogdan-Andrei Iancu]

Hi Andrew,

There are ways to delay the 200 OK, but it is an ugly approach - simply 
use sleep() function in onreply route, but I strongly recommend not to 
do it as it has a huge penalty in performance.

What I rather suggest is to use the new B2B support in opensips - you 
just have to create your own XML scenario to describe the case you have:
