[asterisk-dev] IAX Hardphone (again)

[Bill Shaw]

Thanks for the response Kevin.  The capture was done on my development 
system ( Win/XP ),  but all the devices are on the same Ethernet segment 
so it should (in theory) be the same.  Nothing shows on the Asterisk 
console for this 'new' command,  it's just ignored.

The unknown IE is a call token.  Wireshark doesn't know about call 
tokens. Wireshark apparently doesn't display 0 length IEs properly,  but 
it does pick up parsing IEs ok after so it's just a display issue.

I have calls working in the other direction(outgoing) so I really do 
think I'm close to the end on this project.  Once I get through the 
incoming call setup I should be there.

Best,

Bill
