3928

A call was denied 

because of a basic 

incompatibility 

between the type of 

call and either the 

facilities selected by 

the routing pattern or 

the called user itself.

This error might be helpful as a clue if the customer 
complains of receiving unexpected intercept tone after 
accessing ISDN trunks or PRI endpoints.

1. Determine the trunk group from the circuit pack and 

port number (in the aux data field)

2. check the BCC fields of the pertinent routing patterns.

3. Also, investigate whether or not the calling and called 

endpoints are compatible (for example, some ISDN 
switches may not allow a voice station to call a data 
extension).
