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.
