Has anyone integrated CVP with Avaya? Customer is going to transfer call from Avaya pbx to a T1 line coming into ingress gateway and CVP 9. ICM will send call to Studio app and then, if necessary, call will be transferred back to Avaya using a translation route.

How does/should Avaya pass its call-id to CVP? And then where is it stored in ICM (so I can pass it to the Studio app)?
Thanks! Janine
