Hi,
I would use a softphone for example,
supposing that I have a +212 xxx xxx number for receive calls, I register the proxy 1 with them, and who call me at that number find me.
Now, for make calls I would use another voip plan, so if in the proxy2 I select another provider and I make a call, what happen if somebody call me to the +212 ? The softphone will ring or not becouse I'm in the second proxy plan?
do you understand? how to do it?
thanks
