Pega Call does not support integration to Cisco UCM (using Cisco JTAPI). Yes, there is some older code there as you found. However, this may not work with current Pega Call. Also, it would require the Cisco JTAPI JARs to be loaded into PRPC.
Andrei Trusau, what are you attempting to do? Note that Pega Call provides integration to Cisco UCCE. Refer to Pega Call documentation on PDN for details.
Our customer has Cisco CUCM 10.5 and Cisco UCCX 10.5 (not UCCE) and we are trying to find the way to integrate this with PegaCALL. Using Cisco JTAPI CTI Link for this purporse seemed more or less like a solution for us.
As I undersand from your answer this not gonna work, may be you can give us an advise on general aproach to inegrate CTI with PegaCALL?
We don't have an OOTB integration to UCCX at this point. That's on the roadmap (we are considering integration using Finesse).
What functionality are you looking to implement? If you wish to trigger screen pops in PegaCS, you could start with PegaCall services (OFFERING) from either the UCCX script or from another desktop app (e.g. CAD).
