Forwarding from IPKall to JustVOIP is:
SIP Phone Number: your account with JustVOIP
SIP Proxy: sip.justvoip.com

I've done some testing and it is the Betamax products causing the issue. I can call direct from JustVOIP and it is fine. I can call direct from Gizmo and it is fine. But if I forward to JustVOIP, it does not work.

Gizmoproject is cheap enough...I may just stick with that.

i remember i read in a german voip webboard that justvoip has restrictions on SIP usage. You cant use it with a SIP phone for example. Maybe they also dont allow SIP forwarding with their service.
