SIP Connects Scout to Multiple Telephony Technologies

Scout simultaneously supports multiple VoIP telephony systems using SIP. VPGate registers extensions directly with the SIP Proxy Server and the Scout consoles access extensions through VPGate.

When using a SIP server with a Scout console, the console displays pads on the user interface that map to telephony circuits. These can be actual phone lines tied to a gateway or VoIP extensions off an IP PBX. Scout treats telephone circuits similarly to radios. A console can have multiple lines display on the screen and allow multiple phone calls to be active simultaneously.

In simple applications, 8-port SIP telephony gateways can be used to connect to POTS (plain old telephone service), foreign exchange office (FXO) lines, T1 lines, T1 PRI lines, E1 lines, foreign exchange station (FXS) lines, and Ear and Mouth (E&M) lines. For these scenarios, Scout supports connectivity using the following SIP telephony gateways.

Avtec Model Number Supports
GWC-8FXO-SIP Eight FXO Circuits
GWC-T1-SIP One T1 Circuit
GWC-T1PRI-SIP One T1 Circuit
GWC-8FXS-SIP Eight FXS Circuits
GWC-E1-SIP One E1 Circuit
GWC-8E/M-SIP Eight E&M Circuits

In a VoIP PBX-equipped installation, VPGate registers with the IP PBX and functions with the existing gateways (SIP servers) and desk telephones. Scout endpoints appear as extension registrations. Scout supports the following SIP servers for this scenario:

  • Cisco Unified Communications Manager (formerly CallManager) Version 6.1 and higher
  • Avaya IP Office
  • Generic SIP PBXs
