PBXware

Bicom Systems

White-label and built for service providers, offers partners a fully omnichannel contact center they can bring to market under their own brand (or lighter CC capabilities under a different plan). Agents work from a single workspace across voice, SMS, email, live chat, WhatsApp, and Facebook Messenger, which matters because customers expect continuity regardless of channel. Supervisors get wallboards, live queue visibility, and 40 plus reports, so decisions are based on what is actually happening, not what happened an hour ago. With v8, Voice Agents extend coverage to hours when agents are not available, and multi-CRM support ensures every interaction is automatically logged to the right record without manual entry. Four outbound dialer strategies let providers match the tool to the campaign type.
