Calls dropping with disconnect cause 16 (normal clearing)

pax_2111 · ‎04-04-2006

I am faicing a strange problem within my voice network.

I am using both VoIP and SS7. For VoIP I am using IPIPGW and for SS7 PGW.

Some calls connect normally but immdeiately drop with disconnect cause 16, or ISDN cause 8090 (which mean normal clearing) .

I have difficulty on tracing the cause as I don't know where to start from.

Can someone indicate any poosible cause for this problem or where to start looking at.

First specify where is the clearing message come from ? where do you see it

also intitate a debug for isdn q.931 messages to get deep into the cause...

Ethereal trace of ss7 and h323 call legs for the same call would be uefull in this situation.
