I have a trunk-sipb01.owtalk.com- which gets registered but I can't make calls. I can make calls if I use a softphone and register direct with the SIP server. How can I get around the provider "blocking" my calls through pbxes.com?
I have identified the problem. They only support G729. The softphone I use has G729 but pbxes still does not support it. I am still waiting for pbxes to support G729.
