TL;DR What does VoIP stand for? Voice over Internet Protocol. Your voice travels as data across a broadband connection instead of down a telephone wire. How does a VoIP call actually work? Your voice is digitized, split into packets, routed across an IP network, and reassembled at the other end, usually in well under a fifth of a second. What is a VoIP number? A phone number that belongs to a software account rather than to a physical line at a physical address. That is why it follows you between devices, and why some services refuse it for SMS verification. Should I answer a call labeled "VoIP Caller"? The label identifies the carrier type, not the caller's intent. A legitimate small business and a spam operation can produce the same one, so on its own it tells you very little. What types of VoIP are there? The distinction that carries legal weight is interconnected versus non-interconnected VoIP, not the "fixed versus non-fixed" framing sold by number marketplaces. What do businesses actually use VoIP for? Consolidation, above all. Among 5,700+ G2 reviewers who described the problem they were solving, 28.4% mention putting calls, texts, and video in one place, the most common theme by a wide margin. Who buys VoIP? Mostly small businesses. 63% of reviewers on G2's Fall 2026 Grid Report come from companies of 50 employees or fewer, and top executives write a notably higher share of VoIP reviews than they do across G2 as a whole. How quickly does it pay off? Typical deployments go live in about 1.2 months and pay back in about 12.6 months, down from 14.8 months three years ago. You almost certainly used VoIP today. If you took a WhatsApp call, answered on FaceTime Audio, dialed into a Teams meeting, or called a company whose phone system rang someone's laptop, that call traveled over the internet rather than a telephone line. In this guide, I'll cover what VoIP is, how a call actually gets from your mouth to someone's ear, what a VoIP number is and why some websites reject it, and what more than six thousand businesses on G2 told me they use it for.

TL;DR What is enterprise legal management (ELM)? ELM is the system an in-house legal team uses to track the legal work it owns and control what that work costs, holding matter records and outside counsel spend in one platform. What do ELM platforms include? The category floor is matter management, spend management, and e-billing. Most platforms add intake and workflow, vendor management, reporting, contract management, and legal hold. How does ELM work? It works by structuring data. Law firms submit invoices in the LEDES format using UTBMS billing codes, which is what lets the software test every line against a department's billing guidelines automatically. Is ELM the same as CLM? No. ELM covers all legal work and the money spent on it, while CLM covers contracts from drafting through renewal. Many departments run both. What are the main advantages of ELM? Reviewers report a single system of record, spend visibility on demand, matter status without asking anyone, automated invoice checking, structured intake, and leverage in rate negotiations. What are the main limitations of ELM? Interface complexity, missing features, and rigid custom reporting are the most common complaints, which is notable because reporting is also one of the strongest reasons teams buy. How long does ELM take to implement, and what's the ROI? Products average 2.8 months to go live against a 13-month average payback period, and the category is used across enterprise, mid-market, and small businesses alike. A law firm invoice arrives three months after the work is finished. It runs to dozens of lines. Somewhere in it is an hour billed for a meeting the firm held with itself, which your billing guidelines say you do not pay for. Finding it means reading every line. Multiply that by a few hundred invoices a year, and you have the problem enterprise legal management was built to solve. Legal departments have always known what they spend in total. What they have struggled to say is what they spent it on, which firms were worth the money, and what next quarter is likely to cost. I analyzed more than 100 verified G2 reviews from the past two years and pulled the Fall 2026 Grid Report to work out what ELM actually covers, how it works, and where it falls short.

If your company bought Salesforce Sales Cloud in 2023, look it up on G2 today. It is called Agentforce Sales now. The AI SDRs category sitting next to it didn’t even exist when you signed the contract, and it already lists 400 products.
