Our Unified Comms Platform (3CX) offers some contact centre features for Voice traffic and it has web chat functionality too but it’s not a full blown Contact Centre service.
It is worth noting that many traditional phone system manufacturers add some features like call queuing, reporting and wall boards and then say they have a contact centre solution.
If you need a contact centre solution that brings together all media types and delivers them in a controlled fashion to your agents then you need Puzzel.
Puzzel has all the usual contact centre services like...
Blended media (Voice, Email, Social Media, Web Chat, SMS)
Reporting (historical management info and live wall boards)
Agent management
Queue management
Quality assurance (SLAs)
Survey
Skills based routing
