- Pre-Call Setup – By supporting low level control of ISDN and ISUP signalling messages, pre-call setup processing can be performed to allow decision logic to be used before accepting or refusing an inbound call and thus shortening the call set-up time.
- Conferencing Management – Full control of voice, video and conferencing resources allows for full-duplex (speak and listen/view), half duplex (listen/view only) multi-party conferences. Conferences can be setup to allow three or more parties to participate in conference calls.
- Service Provisioning – Automatic service selection can be based on multiple parameters including, ANI (caller ID), DNIS (indial number), time of day, day of week, date, channel/port and bearer/span. A default service can be used if no criteria are met.
- Failover & Load Balancing – OASIS’ Call Control engine actively manages failover and load balancing. Multiple instances of the media server can serve the Call Control engine; if any of these instances fail, the Call Control engine will attempt to pass the call to another, working, instance.
- Outbound Calls - Via OASIS Call Control, the platform can trigger outbound calls for applications like an outbound predictive dialer and connect to a VoiceXML session once the call is connected (eg for speech or DTMF based marketing campaigns, surveys, notifications, etc).
- Call Fail-Over with Auto-Transfer – In the event, when User Interactive Applications are not available, CCTSL also has the capability to play audio messages to the caller and automatically transfer the call to an operator to complete the call.
- Transaction Recording – OASIS Call Control can allow any call, two-call or multi-party conference calls to be recorded for auditing and archiving purposes.
