[cisco-voip] No Busy to PSTN

[Reto Gassmann]

Hello Group

We have a CUCM 7.1(3a) Cluster and some PRI to the PSTN via 3745 Router.

If we call from a internal extension to a busy other internal extension we
get a busy signal and on the display it shows "Busy".
If we call the busy extension from an ISDN line we get the busy signal and
the ISDN phone shows "Line Busy".

If we call the same busy extension via PSTN we get the busy signal but on
the display it shows "Call Proceed".
If we call from an internal extension to a busy external extension on the
PSTN we get the busy signal and on the  display it shows "Call Proceed".

Why don't we get "Busy" on the display if we call via PSTN?

Has anyone an idea

Thanks Reto
