[cisco-voip] UCCX Call Redirect and Called Address Reset

[Bill Talley]

Anthony,

So I just tested this scenario as you've laid out and was able to replicate
your results.  That said, I encountered different results testing with
internal calls and external inbound calls.

With internal calls like an internal user calling the help desk queue, the
redirected call acted in the manner Anthony described when the Redirecting
Calling Search Space on the CTI Ports was set to anything but Redirecting
Party.  If the RCSS was set to Calling Party or DN Calling Search Space, I
encountered the results you've described in which the called party is
transformed via the transform masking on the route pattern, then delivered
to CUC.  When RCSS is set to Redirecting Party, the call was routed
normally with an untransformed called party.

With external inbound calls, the call was treated the way we would expect
in that the called number is not transformed and was routed to CUC with the
correct called party destination.

The results were the same regardless of whether the route pattern was
visible by the CSS of the CTI port or not.

Hope this helps.
