    Hello friends

    I have a Pbx elastix on US with remote acess.

    and in Brazil I have some extensions SIP that communicates with the Pbx on US

    so the problem is that when I call to extensions they ring but when I answer the phone there is no voice.

    I think i need to set endpoint configuration but I dont know how to do it because the pbx is on US and ext are on Brazil.

    may someone helps me with this issue?



    thank you.

    Are you going through any router/firewall on any of both sides?
    Are you port forwarding RTP ports (10000-20000)?

    Hi all.

    At first, try to verify the rtp port (Like eNoisy said, 10000 to 20000 RTP on udp).
    Second, try to put every nat informations using Freepbx, or using sip_nat.conf file.
    Next, you must put nat=yes on each remote extensions. (Like into your config trunk)
    Select the best choice about your codec.

    Regards
