Roughly, Here’s How We Got To Today…
Arranged in chronological order, the table below showcases the introduction of key telephony features across analog, digital, VoIP, and Cloud technologies, emphasizing the unique capabilities brought forth by VoIP and Cloud technology. This structured timeline provides a comprehensive historical perspective on when these features first emerged, highlighting the swift evolution of VoIP technologies.

The Unreal Capabilities of E-MetroTel’s UCX Software
Voice over IP (VoIP) telephone systems are replacing traditional systems at an unprecedented pace because they offer such a cost-effective, technically sound and feature-rich way to connect people and businesses, all powered by the magic of IP!
While traditional analog and digital phone systems served their purpose for decades, they pale in comparison to the technical prowess of contemporary VoIP telephone devices especially those of E-MetroTel with its patented XSTIM Smart Signaling technology.
Here are some key differentiators that elevate their unique technology to the pinnacle of effective business communications:
XSTIM Smart Signaling
The brains are in the server
E-MetroTel patented XSTIM protocol allows their phone servers to dictate everything that happens on the endpoints. This allows sophisticated, complex features to be deployed centrally.
XSTIM accounts for every key press, every button lit and everything displayed on the device screen. The server maintains control of every user interface for complete system-wide consistency. And call-setup is managed directly by the server, lowering the overall signaling bandwidth utilization.
XSTIM doesn’t rely on STUN servers or complex ALG algorithms to manage NAT Traversal thus simplifying remote device deployment – That’s a huge advantage!
