All the features of the SMS Only package + 5 Agent Seat Virtual Call Center. Though one number can support multiple SMS Campaigns with the use of KEYWORDS, a Click2WebChat Virtual Call Center requires a dedicated PSTN number per campaign. This package enables you to operate a traditional call center that can handle inbound voice, video or SMS (TEXT) routing to the next available logged in agent; or you can link it to a website by embedding provide code and enable visitors to open video, or keyboard chat sessions with Agents. You can buy additional PSTN numbers at any time.
