Hi again 

     In a previous mail I had asked about obtaining the contents/format
of a certain configuration file that the Cisco call manager sends to the
Cisco IP phone. Thank you for the replies. A key phrase in the replies
seemed to be 'adding protocol decoders', so I looked up the mail archives
for all the information I could find about this. I found that these
protocol decoders were actually C files (and I almost passed out when I
saw the contents of one of the C files). It looked really really
difficult. Now c'mon all of you'll had a 'first time' with these protocol
decoders, so could anyone, (anyone !), please explain if :
1. There is an easier way of going about getting the contents of the file
I need.
2. How do I go about getting the information needed to write a protocol
decoder (yes, I did take a look at the mini-tutorial gilbert wrote in the 
archives)

 The main protocols that are used by the Cisco phone are bootp, dhcp,rtp,
voip protocol (most of which are documented in the ethereal manpage). I
also noticed that the CIsco discovery protocol and the Cisco Interior
Gateway Routing Protocol have been documented in the ethereal man
page. Would the code for that help, and if so, how could I get the
protocol decoders for the other cisco products.

I would really appreciate any help anyone can give me. I would be happy to
share all the information I am able to get from these experiments and
others I have carried out.

Thanks again (and please .... please help a first timer!)
