Incomming calls dropping Cause=96

[nathanbland]

I have customer who is reporting incomming calls dropping out before completing, Monitor trace shows Cause=96. I have looked up the Etsi cause code for 96 but it is a little unclear whether this a problem from the exchange or on the terminating equipment, just wondering if anyone else has seen this on an IP406 running 3.2 software.

Read this:

Cause No. 96 - mandatory information element is missing.
This cause indicates that the equipment sending this cause has received a message which is missing an information element which must be present in the message before that message can be processed.
What it means:
This is rarely seen in North America but usually means that the number that is being dialed is in the wrong format, (similar to cause 88). Some part of the format being used is not understood by either the remote side equipment or the switching equipment between the source and destination of the call.



Cause No. 88 - incompatible destination.
This cause indicates that the equipment sending this cause has received a request to establish a call which has low layer compatibility. high layer compatibility or other compatibility attributes (e.g., data rate) which cannot be accommodated.
What it means:
1. This usually means that the Number To Dial in the Connection Profile is in the wrong format. You may need to dial a 10 or 11 digit number, or dial a 9 in front of the number if it is a Centrex line.
2. This problem may also give a Cause 111.
3. Dialing at the wrong line speed can also give this Cause.
