Hi everyone!
The problem has been solved, by following the suggestion from an email sent to me,
from my provider Callwithus.
This is the email;
The problem is not related to the DID (DID has nothing to do with outgoing
calls), but in your equipment. Try to set "
proxy audio" parameter in "
voip
accounts" menu on our web site to "
always"
I want to give recognition to
Sergey-CallWithUs.com, the solver of the problem.
Many thanks to you Sergey.
