softphone registration failure
I ran a packet sniffer on my computer and tried to use my soft phone on my own computer. Saw registration attempt. I'll attach it as an image here I guess.

The 192. address is the computer with softphone.

Now, please note this is not using DNS SRV. But, on my neighbors' ISP connections it DOES register and work normally. My ATAs are set for DNS SRV and they only are working when I bring them to my neighbors' ISP connections.

Have you sent the contents of those four packets to CC. You know you have an authentication failure. The first two SIP transactions look standard. The problem probably probably lies in third packet. You need to examine it to see what was being sent back to CC to cause it to fail. It would also be interesting to examine the packets when it is successful at your neighbors.
