Problem with SipDroid

[bhuether]

I installed it on my MT3G and have it working with sipdiscount.com (using their server and login info). But I can't get the pbxes.org config to work. I have followed all steps and have triple checked my settings. I have a pbxes username and extension (300). I have a trunk specified and an outbound route. But all that happens is I get a registration failed error - 404 not found. and yes, I am entering the pbxes username with a -300. I really am doing everything right...

Any ideas? This seems to suggest a pbxes issue.

thanks,

brian
