Hi all, We are having an issue with Random Disconnects wit our PRI
connection. We are going into a T100P card from a Cisco IAD. Below is a copy of our PRI Debug. We will be talking on the phone and all the sudden the line
will go dead. It acts as if the remote party hungup. However, the remote party
is not hanging up. Can anyone give me some hints on where to look for the cause
of this? -- Zap/25-1 is ringing > Protocol Discriminator: Q.931 (8) len=9 > Call Ref: len= 2 (reference 44/0x2C) (Terminator) > Message type: ALERTING (1) > [1e 02 81 88] > Progress Indicator (len= 4) [ Ext: 1 Coding: CCITT
