I’m connecting to Telepacket (the SIP provider) from Asterisk. When I use it to make local calls to the US, like my cell phone or wife’s work etc, there is no problem at all. However, when I try to place an international call, I don’t hear any sound. I don’t hear a ringing, or them answer. They also do not hear anything. And it doesn’t appear that key tones are sent either (I called another Asterisk PBX that I manage in England).
Considering that local calls, and toll-free US numbers are working, why are International calls not working? I’ve tried calling the UK and the Netherlands and I’m getting the same problem. It DOES call them, and they DO pick up, but neither side can hear anything.
