Transfer call to IVRS outside Vicidial

[macaruchi]

I have a new requirement from my company and I want to see if anyone here can point me in the right direction to resolve this.
I have developed an IVRS for credit card payments using Asterisk, FastAgi and Java, now they ask me for this IVRS to work together with ViciDial so that when transferring to a specific extension the IVRS answers. I have only configured IVRS from Vicidial itself, never something like this. I'm thinking about creating an extension from Asterisk and adding it directly to extensions.conf, it's the only thing I can think of but I would like more to not have to touch anything other than through Vicidial itself, could there be a way or an idea to avoid doing it? thus?

Maybe this is not a problem but I dont a clear idea yet
Thks In Advance
