    Phone Model: iPhone OSv8.4
    Generation: 4G
    Firmware Version: 2.41.00?? (modem firmware)
    Jailbreak: NO
    Cydia Installed: NO

    Issue Info
    Handset: Phone
    Contacts: Local
    Connection: 3G
    Server: external

    Have 3 iPhone users who have no audio (2way) when calling internal xtns. External calls are fine. The external xtn test calls have been to 3CXPhone clients on Windows/iPhone/and Android, all with same result no audio both ways.

    Any suggestions much appreciated.
    We are on a hosted 3CX server (v12), so all are outside LAN.
    - none of the test calls that had no audio were while connected to any Wifi networks.

    Are you using the 3CX SBC locally? If not, what are the extensions behind?

    Other ext to ext calls are all ok?

    Does the 3CX Server log, show any errors, on one of these calls?
