Set the default Session Border Controller (SBC) behaviour. A Session Border Controller is a SIP provider account which takes over the PBX functionality of the Mediagateway. The 'DDIMode' of the used SIP provider account has to be anything but 'off'. All internal and external activities are controlled by the SBC. If the SBC is disabled ('-1') or the SBC is not available the Mediagateway uses the internal PBX functionality. Auto mode ('0') means that a separate SIP account is used for each existing extension entry (so in this case it is not possible to set one global SBC). In auto mode each voipExtensionTable entry needs a matching voipProviderTable/voipSipProviderTable entry. So in auto mode Mediagateway pairs SIP provider accounts and their matching extensions. Possible values: -1 -> SBC is disabled; 0 -> Auto mode; 1...999 -> Index of a voipSipProviderTable entry (has to be a SIP trunk provider). |
