STAC VIP Control Surface

STAC VIP utilizes the familiar STAC Control Surface which provides clear indication of phone line and caller status. Super bright colored LEDs and an ergonomically friendly button layout give a concise overview and control of all callers at a glance.

VoIP

At the core of STAC VIP is a sophisticated engine that can process various types of incoming calls. For years, VoIP telephony has provided consumers with low cost, high quality communications and now STAC VIP can deliver those same benefits to broadcasters. STAC VIP can process up to 6* incoming VoIP calls on a single DSL line utilizing telephone grade G.729 audio compression. By employing a single DSL versus multiple POTS or ISDN phone lines, huge cost savings are easily realized.

Legacy POTS/ISDN

While many STAC VIP users might consider going entirely VoIP, some customers still rely on traditional POTS and ISDN phone lines. STAC VIP can easily accommodate these by use of VoIP Gateway devices which are commercially available from several manufacturers. This allows for existing POTS/PSTN, ISDN and T1/E1 telephone lines to be converted to a SIP compatible VoIP trunk for connection to the STAC VIP Mainframe.

IP PBX

Numerous broadcast facilities depend on IP-based PBX systems to deliver telephone calls throughout their offices. STAC VIP simplifies the process by allowing for easy extension sharing and integration with SIP-based PBX systems.

Wideband "HD Voice"

STAC VIP provides the ability to accept incoming wideband voice calls from these new VoIP telephones as well as wideband voice capable Smartphones and soft codecs. Now your callers can sound like in-studio guests!
