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 for the cause value generated by the network.
- Trunk group: Direction: The Communication Manager field 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 is attempting to make an outgoing call over this trunk group, which is an incoming call 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 another D-channel. The outgoing trunk group is CBC but no overwrite the incoming NSF, no service or feature is specified on the outgoing route pattern. 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.
