[OpenSIPS-Users] Prepaid time remaining announcement?

[Adrian Georgescu]

Hi Chris,

Out of the box call-control will not do such thing. You can of course modify it to do something before call expiration. Finding the relay and making it play something is a pretty ugly hack.

In my experience playing prompts in the middle of an established session can be done reliable only by inserting a fully fledged B2BUA. This is the price you have to pay for adding such feature. Other hacks will fail in one way or another depending on flow scenario, codecs etc...
