[OpenSIPS-Users] Avoid waiting in opensips.cfg

[Muhammad Shahzad Shafi]

Its simple, set invite try timer to appropriate value,


http://www.opensips.org/html/docs/modules/1.11.x/tm.html#fr_timeout


then send it to some impossible path, 

sip:$tU at 127.0.0.1:5060 

after
try timer times out, you will get back the original invite in failure
route, where you can send it actual destination to send it again to
"go-around" trip to impossible destination. Of course while this is
happening, you should send fake "180 Ringing" message to caller so s/he
won't suffer from dead-air silence. 

Thank you.
