Help with Q931 trace

Hi

Whilst debugging an ISDN / MGCP gateway the following appeared :

Gateway#

Aug 5 13:41:37.108 bst: ISDN Se0/1/0:15 Q931: RX <- FACILITY pd = 8 callref = N/A

Facility i = 0x91A1130202400002010C300A0A01010A0103A0028100

What does the "Protocol Profile = Remote Operations Protocol

0xA1130202400002010C300A0A01010A0103A0028200

Component = Invoke component, Unsupported operation "

Part mean, we are currently having a problem with a small number of incoming calls not connecting.

Thanks

Re: Help with Q931 trace

We need the call being offered since the beginning include calling, called and timestamps.

Thats just part of a call and facility messages not being understood

Re: Help with Q931 trace

Below is the complete trace from one of the gateways, ie their were no existing calls or call setup attempts in progress when the debug started
