TR-104
                                            The device supports TR-104 for configuration. This support is for the SIP (VoIP) application layer and applies to FXS interfaces (lines) only. TR-104 defines a "data model" template for TR-069 enabled devices. The "data model" that is applicable to your AudioCodes device is defined in the DSL Forum TR-104 – "DSLHome™ Provisioning Parameters for VoIP CPE". 
                                            The hierarchical tree structure of the supported TR-104 objects is shown below:
