Recommendation
If customer is complaining of unexpected intercept tones
when accessing ISDN trunks or PRI endpoints and no other
cause can be found, escalate the problem and provide the
next tier with this Error Log information.
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.
Follow the previous recommendation for Error Type 3890.
This error might be helpful as a clue if the customer
complains of receiving unexpected intercept tone after
accessing ISDN trunks or PRI endpoints. Determine the
trunk group from the circuit pack and port number (in the
aux data field) and then check the BCC fields of the
pertinent routing patterns. 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).
