ekiga gets stuck on standby

[electhor]

Binary package hint: ekiga

I have gone to considerable difficulty getting ekiga to a point where it connects to the ekiga '500' address and I can successfully do the audio test where I can hear what I have said return through the earphones during the druid setup phase. My account is recognized as being registered, but it won't connect to another ekiga user. It is stuck in 'standby' mode and does nothing, other than immediately disconnect. Previously I could connect to another ekiga user via an IM connection, but had no audio, due to having a 'symmetric' router issue. Now all the settings seem to be right, ie the 'sip:<email address hidden>' connects, I have a registered account and I have what I believe is a correct static IP address (sorry not great at network stuff) going to a STUN server - I get no IM any longer, and still have no audio to another ekiga account - The problem seems to be no connection, but if all the settings are working as attested to by the setup wizard/druid, what is the issue? Does the setup wizard work correctly or is it in error? I am happy to supply logs and anything requested.
The computer has a gigabyte ma770-ds3 motherboard, 4800+ amd dual core cpu, 2gb of 800mhz ram, nvidia 8600 gpu. Headphones are logitech and plug straight into the sound card.
Thank you.
