Acumen Consulting is a high quality VOIP Phone System installer in the St Louis region.

Modern phone systems provide a significant cost saving over legacy PBX systems.  Voice over IP allow office phones to connect over Ethernet cable instead of dedicated phone wires.  These systems also provide advanced features for phone systems such as rapid extension changes, automated attendants, call groups, and special forwarding rules.

With SIP-based Internet voice services, you can reduce your phone bill by over 50%.  Monthly service saving can pay for a new VoIP phone system within 12 months.  Ask us to show you how you can save.

We can help with complex configurations and sound issues, VLAN configuration, QoS configuration (Quality of Service), and Power over Ethernet (PoE).

We can help with ring groups, auto attendant / digital receptionist configuration, mobility concerns, and call center management.

There are a number of VOIP for business phone services available.
