Stacey,
It sounds like you didn't forward the UDP ports. Alternatively, you could have used the DMZ. This is covered in my checklist.
I don't understand what you mean by "set up both RRC's to point to the unique DDNS address". You only put that in the control
RRC's SIP Contact field.
I would have gotten this going in 10 minutes for you this afternoon, but I guess you wanted to do it yourself. Just follow my checklist
and you will get it working.

What I meant about pointing both to the DDNS address is I have the DDNS address in the "SIP Contact" on the control RRC. I put a unique SIP password on both the control and radio RRC's.
On the local router and remote router, using port range forwarding, ports 13000 (SIP port), 13001 (UDP audio port) and, 13002 (UDP cmd port) are forwarded, each using UDP.
Didn't have Teamspeak. Installed it.
