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

[Andrew Pogrebennyk]

Hi,

I am looking for the ability to send media backward before a call is 
established, allowing the remote side to send some DTMF before a call is 
established. For that purpose, is it possible to delay 200 OK on 
OpenSIPS for a pre-configured interval?

So far I have considered the b2bua module, embedding the execution of 
Perl function with perl.so and some alternatives like SEMS and its 
ann_b2b application from iptel or sippy b2bua but found nothing that 
allow me do this without extra considerable development effort.

Sure it would be better and more correct to implement this logic on the 
remote side, but for some reason this is not an option. Any ideas?
