Communicate immediately across channels

- Preconfigured channels: communicate with any combination of endpoints (other Sigma Client users, traditional and MANET radio nets, and telephone/softphone users) in a single voice channel
- Monitor and communicate across multiple channels simultaneously
- UI is optimized for situational awareness. Active members are indicated with a checkmark and channels turn green to show the active speaker.
- The Channels feature is currently available on the Sigma Clients for ATAK and Windows.
Chat optimized for the tactical edge
- Unified chat via both XMPP and IRC protocols means users no longer have to switch between different chat clients
- Operational tempo is enhanced with the ability to send images and attachments directly in chat, reducing the need for email
- Urgent message tags help users visually identify critical messages
- On the Windows client, chat panels can be resized and rearranged to fit the needs of each individual user, and unused panels (such as the dialer or contact details) can be hidden to maximize the space available for chat sessions
- Chat is only available on the Windows and Android clients.
