Decoding QSIG/Q931 Facility Messages

Do any of you know how to interpret the "Facility i = " field in the output

of "debug isdn q931" ? I'm trying to debug some QSIG call transfer and path

replacement stuff and I can't figure out what I'm even looking at.

As an example:

*Nov 10 19:12:56.031: ISDN Se0/0/0:23 Q931: TX -> FACILITY pd = 8 callref =

0x0022

Facility i =

0x9FAA068001008201008B0100A11F02020A0002010C30160A0101A00EA5090A010412043738

32300A01030A0100

How do I figure out which q931 message that actually is? It is most likely a

QSIG call transfer message, but I need to know for sure, and I also need to

figure out which messages in my logs are QSIG path replacement messages.

Any ideas?

Thanks!

John

Hi John,

Please take a look at the following:

ECMA Q.SIG Specifications - 11.3.3 Facility - Table 30
