    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...

    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?
