One outbound provider works, other doesn't

[khabibul35]

Hi, I've just started up and have been receiving calls with Gizmo without a hitch. However, outgoing is a different story. At first, I thought outgoing was working fine as well. Then, I finally got past the 3 minute mark and realized I was calling through Gizmo. When I switched my outgoing to Betamax, suddenly when I called, the other party couldn't hear me, though I could hear them.

Now, usually, I would assume it's the VOIP connection or router, but under this circumstance it seems to me it's gotta be on voxalot's end. Are the any special settings I need to enter under the providers tab? I don't see much of difference in option except that gizmo is registered and that webcalldirect is not but that shouldn't matter for outgoing right?

Any ideas?
