Frequently Asked Questions

What business phone systems does RevSA install?

RevSA deploys cloud PBX and hosted VoIP, 3CX unified communications, and on-premise IP telephony. Systems include IVR auto-attendants, call routing, voicemail-to-email, and mobile/softphone extensions so staff stay reachable in the office or remotely.

Is VoIP reliable for South African businesses given loadshedding and connectivity?

Yes, when designed correctly. RevSA pairs VoIP with resilient connectivity (fibre plus LTE/SD-WAN failover) and power-continuity planning so calls survive outages. Call quality is protected with QoS on the network and SIP trunks sized to your concurrent-call needs.

Can RevSA move our existing numbers to a new VoIP system?

Yes. Existing geographic and ported numbers can be migrated to the new platform so you keep your published numbers. RevSA manages porting, trunk provisioning and cutover to minimise downtime during the switch.

Does RevSA support remote and hybrid teams on voice?

Yes. Softphone and mobile apps extend the same extension, IVR and call-routing experience to remote staff. Hybrid teams get one unified system regardless of location — no separate personal numbers required.
