Sandipan,

     The error is coming from the telco switch,

     82—the public network near the local user (local telco switch)

     86- Channel unacceptable The service quality of the specified channel is insufficient to                 accept the connection. The call attempt fails because the channel is unusable.                               If you use a PBX, check the configuration of the PBX. For a PRI,                 find out how many channels your telco provides.

     Could you post more of the error debug?

     Which channel are you trying to pass the call out? Try reversing the channel selection order as a test.

     Is this a full 30 channel E1?

     The best advice I can give you is speak to the ISDN provider as this line may not be provisioned ready for use or may not be a full 30 channel E1.

Hope this helps,

Craig
