Hi folks, I'm trying to setup a system where i'll have one local number in Brazil to server our office there and here (USA). Here is the scenario: - 3CX PBX Software is installed on a dedicated server (Datacenter on Texas) - The line it has is a VoIP lines provided buy an American company - Since the number (in the VoIP line) is an New Jersey/USA number and we needed a number from Brazil, we got a virtual number (brazilian number) routed to this VoIP line - Our offices are in New Jersey/USA and in Brazil - Some results . From extension to extension (Brazil x USA) using softphone, the quality is great. . From a USA extension (soft phone) to any number in Brazil (PSTN line) it works very well . if somebody in brazil (PSTN line) calls the virtual number (which is routed to the VoIP line) he/she will get the Digital Secretary. If the call is transfered to my extension in US, the quality is still good but... HERE IS THE PROBLEM: If this call is transfered to an extension in Brazil, the quality is terrible: the sound is choppy and cutting off. Anyone has an ideia to help on this?
