Bria 4 computer to Voipo configuration

[wbrisett]

I'm wondering if anybody who has Voipo use Bria 4 on their computer for calls. Ironically, this use to work, but now when I call the local dial-in number for the conference call system we have at work, I immediately get at fastbusy signal. Our area uses an area code in front of local numbers, and I've tried with and with a +1 in front of that, but neither made any difference.

I currently have bria 4 configured like this:

UserID: <my username according to the vpanel>
Doman: sip.voipwelcome.com
Password: <my password>
Display Name: <my first name>, but I don't think that matters

Under Domain Proxy:
Register with domain and receive calls: Enabled
Send outbound via: Domain --- I also had Proxy enabled for a time with sip.voipwelcome.com:5078 as the proxy ... however never of these seemed to make a difference

Dial Plan: #1\a\a.T;match=1;prestrip=2; --- I believe this is the default.

Under Topology I have Auto Detect enabled (default)
Presence: (default) Peer-to-Peer
Transport: Signaling transport (Automatic) enabled. I have also played with setting this to UDP and TCP, but nothing seemed to make a difference, so I put it at automatic.
IPv6: Not enabled

Advanced is left to default. But I'm wondering if I need to enable Outbound

Anybody have any ideas on why this configuration isn't working with Voipo??

I've gone and setup another account with a different voip provider and it works straightaway without changing any settings in Bria4 other than the basic account information.
