Trouble registering with Sip?

[fisamo]

I was checking out some settings on my * system, and I saw that it was not registering to sip.voipwelcome.com. Looking at my logs, I just saw timeout, no authentication issues. To no surprise, my vPanel showed no devices registered.

I changed the trunk to register with jupiter.voipwelcome.com, and it registered just fine. I changed back to sip and I'm getting timeouts. It's a rare day to see 'Request Sent' instead of 'Registered' next to the voipo trunk...
