    Hi,

    I have two LinkSys 941 phones
    Phone 1 Ext1 is 100 3cx extension
    Phone 1 Ext2 is 120 3cx extension

    Phone 2 Ext1 is 101 3cx extension
    Phone 2 Ext2 is 121 3cx extension

    Extensions 120 and 121 registered fine (have green light on Line status page).
    Also 120 and 121 could receive inbound calls.

    I can call from 100 to 101, but not to 121 or 120. Same with phone 2 I can call from 101 to 100, but not to 120 or 121.
    Why so?

    I forgot to mention I cannot call because it is busy.

    Hi,

    If I understand correct, you have a box, with 2 FXS lines on.
    In that case, the need is to use a different port to register to.
    let´s say. Line 1 registers with port 5060, and line2 registers with port 5061

    Can you check this ?
    I have with other FXS systems had similar errors, but the port numbers were not settable.
    These errors were solved, when I changed software versions (controlled).

    Regards,

    Daniel
