[asterisk-dev] IAX Hardphone (again)

[Bill Shaw]

Did I misunderstand the calltoken usage?  I thought I was to send a 
calltoken with 0 length data in my 'new' to indicate to the PBX that I 
could handle call tokens?  No?

I did a packet capture and uploaded a short Wireshark capture file to:
http://b.shaw.home.comcast.net/new.pcap

Best,

Bill
