Cause
The call cannot be completed because the called user cannot accept the call delivered in the SETUP message.
This cause value has end-to-end significance. Communication Manager returns this cause value to the user who has originated the call.
Proposed Solution
Procedure
Check Communication Manager administration (network generated the cause value).
- Trunk group: Direction: Communication Manager is set to two-way on a trunk group that the ISDN network has configured as outgoing only, relative to the CO switch, and a user on Communication Manager attempts to make an outgoing call over this trunk group to the CO.
- On tandem calls through Communication Manager from ISDN trunks to ISDN trunks, an NSF for a one-way service, for example, Megacom 800, is sequenced from one D-channel to the other D-channel. The outgoing trunk group is CBC but no service or feature was specified on the outgoing route pattern to overwrite the incoming NSF. Add the correct service or feature to the route pattern or make the outgoing trunk group a static trunk group. For example, public-network or tie.
