[Asterisk-Users] registration at Voipbuster times out

[Remko Muis]

Hi Francesco,
No, I'm using the DNS servers of my ISP (Wanadoo). Here is the output of 
traceroute:

[root at marnix asterisk]# traceroute sip.voipbuster.com
traceroute: Warning: sip.voipbuster.com has multiple addresses; using 
194.120.0.203

Tja....
And remember: connecting to voipbuster is only a problem for Asterisk, not 
with direct connections between softphones and voipbuster!

Best,
Remko

Remko,

What IP's do you get returned for sip.voipbuster.com?
Do you use UU-net's DNS servers? If so, you might try using different
servers, as I have had some weird experiences with their DNS servers in
the past.

Have you tried trace-routing to the server to see where it breaks?

I am using voipbuster as well, and am usually able to connect just fine...

Good luck!
