I have to troubleshooting a problem of congestion on ISDN line. I see from my CCM that I have a lots of 41(Temporary failure), 44(Requested circuit/channel not available), 102(Recovery on timer expires) occurs.
Someone can drive me where to find detailed informations about of this codes?
I have already googling in web and search in cisco site, I find some information, but I would find a detailed description of this codes. If someone can also give me a book title could be great.
Thank you really much.
Best regards Antonello.
