Recently for a large law enforcement project our team built a radio recording integration for Twisted Pair WAVE Communications platform. The integration allows shared Twisted Pair and Verba customers to extend their recording system, and add the capability to record radio communications in their command and control centers.
Twisted Pair – a Motorola Solutions Company
Twisted Pair, now a subsidiary of Motorola, is a UK-based vendor, that provide the defense/military, commercial and the public sector markets with voice, video and data critical communications solutions. Their flagship product, the WAVE platform, is an IP-based real-time communications solution, that connects multiple legacy and IP-based communications platform, into a single, unified system and removes technical barriers, that formerly existed between various solution.
WAVE provides Communicator applications for various platforms, they work especially well in dispatch scenarios. To get a glimpse of their solution, here is a screenshot of their Desktop Communicator console:
Recording police radio with WAVE and Verba
Take the following use case: a police officer on duty in the field uses their radio to communicate with their command center. Their radios use numerous radio channels, defined for various groups and purposes.
In the realm of phone call recording, the Verba solution identifies a caller and a called party, whereas here the Verba system is recording radio channels. When a radio channel is terminated in WAVE, the content is streamed to Verba, channels are identified and properly logged. The streams are coming from dispatch boxes, that are components with the various radio infrastructures, used by our customers.
This is how it works:
the Verba general media recorder listens on UDP ports (either unicast or multicast ports) for streaming media from radio platforms
based on port information, the streams ports are mapped into a radio channel
- radio ports are defined in Verba as regular extensions, therefore all our access control and record sharing policies can be used to provide secure access to radio recordings to the team
the Verba solution creates separate recordings for various burst of radio traffic, so the system is both efficient with storage use and gives you a great timeline of communications, even across multiple channels
since records are appearing as standard media recordings in the Verba Recording System, all our standard features apply: silent monitor, markers, comments, configurable data retention policies, export/import and transcoding capabilities, etc
WAVE provides three options for recording – Verba supports all of them:
Unicast RTP (real-time protocol, industry standard in VOIP) streaming
Multicast RTP streaming
VoIP radio gateway – the Verba dial-in recorder can accept and record VoIP calls sent by VoIP gateways
Supported radio solutions
WAVE integrates with various platforms, and all those can be recorded by Verba if WAVE is also used in the deployed platform:
- APCO P25 – ASTRO 25
- MPT 1327
- PassPort (Trident Micro)
It also supports various radio gateways:
- Bosch Telex IP-223 / NI-223
- By-Light TRICS
- C4i RIU
- Cisco 2800 Series Router E&M
- Dialogic DMG4000
- Raytheon JPS NXU-2 / ACU-1000 / ACU-2000 (shown above)
- Vocality BASICS Radio and Voice IP product lines
- Voice Interop AM-360
