Hi there!

I found an issue when upgrading my DIR-825 to latest trunk. Asterisk failed to register to my voip provider, and no other UDP SIP phone would register with it. Also, asterisk cpu utilization went to 100%.
My sip.conf looked like this:

[general]
...
register => user:pass@voip-provider.com/number

[phone1]
type=friend
host=dynamic
...
[voip_provider]                                            
type=peer                                                       
host=voip-provider.com
...

With strace I saw this repeating all the time:

1837  open("/etc/resolv.conf", O_RDONLY) = 11
1837  ioctl(11, SNDCTL_TMR_TIMEBASE or TCGETS, 0xb72180b4) = -1 ENOTTY (Inappropriate ioctl for device)
1837  read(11, "search lan\nnameserver 127.0.0.1\n", 4096) = 32
1837  read(11, "", 4096)                = 0
1837  close(11)                         = 0

Changing the register line to:

egister => user:pass@ipaddress/number

worked around the issue.
Interestingly, the peer connected without problems even with the dns name in the 'host=' line, the problem is only with the 'register =>" line.

The discussion might have continued from here.
