3906 Protocol detail; may offer a
clue if customer is having
ISDN calls denied with an
unexpected intercept tone. 1. If customer is complaining of unexpected
intercept tones when accessing ISDN
trunks or PRI endpoints and no other
cause can be found, escalate to the
problem and provide the next tier with this
Error Log information.
3909 A request to use a network
service has been made, but
the network has rejected
the request because the
requested service is not
implemented. 1. Follow the recommendations listed above
for Error Type 3890.
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).
