    I am using the latest build of 3CX and have 10 Polycom 501 phones. All calls ring to extention 110. If no answer there, ring to Digital Receptionist.
    when calls answered at 110, or any other phone, are transferred, the following log entries show up.

    11:47:57.703 StratInOut::eek:nHangUp [CM104007] Call(793): Call from Ext.110 to 113 has been terminated by Ext.110; cause: CANCEL; from IP:

    All Lines from VOIP Provider have PBX delivers audio checked, and all extentions have Bind to Media server checked.

    Phones have latest version of SIP files installed (2.1.2)

    Any Ideas?

    Fixed it

    Changed SIP ID in Other options in extension management to extension number, Uncheck support Re-invite and support 'replace'header boxes.

    blind and attended transfers now work.
