Looking back through the list archives, I spied this thread which refers 
to the same model of home router as in this case:

http://www.mail-archive.com/ekiga-list gnome org/msg08142.html

It also describes a similar symptom ("The various test SIP addresses 
that are supposed to playback sounds also don't work for me"). I'll have 
a closer look at this and report back to the list if I find a 
configuration that works.

Cheers,
Dave
