[Blink] Newbie: How do I setup ICE?

[Etienne M. Gagnon]

Hi there,

I'm new to blink. I've got it to work nicely at home. But, at work, it 
seems that we have a pretty restrictive firewall. Blink doesn't connect 
to the sip2sip server.

In the logs, I can read:

ACTIVITY
...
2010-12-09 15:13:56   Account('xxxxxxx at sip2sip.info') failed to 
register: DNS lookup failed: Timeout in lookup for routes for SIP URI 
sip:sip2sip.info (retrying in 42.64 seconds)
2010-12-09 15:13:56   Error: The account xxxxxxx at sip2sip.info failed to 
register(DNS lookup failed: Timeout in lookup for routes for SIP URI 
sip:sip2sip.info)

SIP
...
2010-12-09 15:15:14.394054: DNS lookup SRV _stun._udp.sip2sip.info 
failed: no response received, the query has timed out
2010-12-09 15:15:15.176399: DNS lookup NAPTR sip2sip.info failed: no 
response received, the query has timed out

I read, on the help page, that ICE should help. But, I can't figure out 
how to set it up.

Thanks for any help you can provide!
