Hi all, Just wondering if anyone else has had issues with calls to Brazil? I've two 3cx phone systems one in the UK & U.S. But I can't get calls to Brazil to be reliable. I've tried a few different things, using our ISDN30 line sin the UK, using a VOIP line we have in the UK & also routing calls from our UK system to US system and out of their VOIP lines. Sometimes the calls connect, sometimes they ring and ring when the call isn't actually going through to the other end. EG: it sounds like it is ringing but the phone on the receiving end doesn't ring. Other times the calls cut in and out. I'm aware that Brazil has a rather ropey phone setup and call quality is usually an issue, but is there anything else I can do to improve this situation?
