Let's pick some terms to agree upon.
Your Internet Service Provider (ISP) provides you with an Internet 
connection.

You have selected dyndns to be a domain name provider. It joins your 
dyndns domain name to your ISP ip address.

All ekiga wants is a Voice Over IP (VOIP) provider which you use in 
ekiga Account registar and Name fields.

When you fire up ekiga, it calls your VOIP provider's server, gives your 
id/pw and your VOIP's servers now knows your ip address provided by your 
ISP.

It then sends any calls back to that IP, which happens to be your 
router's Internet WAN address.

As you can see, dyndns was nowhere in the loop. For ekiga software to 
receive a call, someone calls your VOIP id, the VOIP server looks up 
your id, gets the ip address where your id/pw showed up on, and sends a 
udp packet to that IP on port 5060. Your router should forward that WAN 
packet to your LAN ip node where the ekiga application would accept the 
incoming call.

In my setup, I have three nodes on my LAN. I have to tell the router to 
forward the ekiga/sip ports to the WAN ip address where I have the ekiga 
application running in order to originate or receive any calls.

You either hard code the LAN ip address to forward your SIP traffic, or 
you have to configure your router to dynamically configure the required 
ports to the LAN ip address which opens port 3478 or 3479, if possible.

I am pretty sure you will not get dyndns to provide your LAN ip address 
unless your router is in a bridge mode where the LAN ip address is the 
WAN ip address.

If you are running linux, "hostname --ip-address" would return your LAN ip,
