Foundational guides to communications infrastructure — what CPaaS, voice AI, and RCS Business Messaging are, how they work, and how to build with them on Orbit by Devotel.
A small business choosing contact center infrastructure in 2026 should screen alternatives on five things — one contact record, a native AI agent, owner-operated termination, pay-as-you-go pricing, and self-serve onboarding — before quoting a seat licence.
A buyer's guide matching the two alternative shapes a small business chooses between for voice in 2026 — an API-only self-serve platform or a carrier-of-record omnichannel platform — with the five decision points that settle which one fits a lean team.
A buyer's guide for a small business evaluating alternatives for voice and messaging in 2026 — seat-licensed phone licences, API-only self-serve platforms, and the carrier-of-record omnichannel alternative with native AI agents — plus a six-step decision framework.
An omnichannel communications platform connects voice, SMS, WhatsApp, RCS, email, video, and chat on one stack, so every conversation shares the same routing, contact record, and history. Definitions, FAQs, and how Orbit runs all nine pillars under one account.
A buyer's guide for businesses that need integrated voice, messaging, and AI agent capabilities — not one channel with an AI add-on. What the alternatives actually are in 2026, and how to evaluate them on criteria that hold up in production.
A feature checklist tells you what a vendor supports. It doesn't tell you who owns the termination path in each country, who carries the compliance risk, or whether your contact record actually stays unified across channels. Here's the evaluation framework that does.
The two alternative categories a small business actually compares in 2026 — seat-licensed phone systems and pay-as-you-go communications platforms (CPaaS) — and the criteria that settle the choice: billing model, one contact record across channels, outbound termination ownership, and whether AI agents are native or bolted on.
The concrete criteria worth scoring a carrier of record or omnichannel communications platform on in 2026 — network ownership, termination paths, per-market compliance, one unified contact record, unit-of-work pricing, and the proofs a demo can survive.
The regulatory topics every CPaaS buyer asks about in procurement — the TCPA dialing window and consent rules, US 10DLC brand and campaign registration, STIR/SHAKEN attestation levels, and opt-out handling — explained in one place, with pointers to the controls each topic maps to.
A wallet pass is not a message — it is a document that lives in the phone's wallet app. This guide explains where passes fit next to SMS and RCS in an omnichannel engagement strategy, and how Orbit issues, updates, and delivers Apple and Google Wallet passes anywhere a link can travel.
A buyer's guide to the platforms worth shortlisting in 2026 when a company wants AI agents that work across channels — not a standalone voice-bot or chatbot. What the alternatives actually are, and how to compare them on criteria that show up in production.
SMS deliverability is the share of sent messages carriers actually accept and hand to the handset — a different number from raw throughput. This playbook covers the pre-flight checklist (10DLC brand and campaign registration, sender pool hygiene, throughput vs reply ratio), how to read delivered/failed per pool, and a worked weekly report you can run in the Orbit dashboard.
A CPaaS lets developers add voice, SMS, WhatsApp, RCS, email, and video to their apps through a single API — no carrier contracts, no telecom infrastructure. Here is how CPaaS works, what it is used for, and how Orbit unifies all nine communication pillars on one platform.
The WhatsApp Business API is Meta's programmatic messaging platform for sending and receiving WhatsApp messages at scale — but on its own it is one channel, not an omnichannel strategy. Here is what it is, what it is not, and how it fits alongside SMS, voice, and email in a unified customer conversation.
Stitching together a dialer, an SMS gateway, an email sender, and a WhatsApp BSP looks cheaper line by line. Here's what that comparison misses once you count integration upkeep, support ownership, and the cost of a contact record split across four systems — and where a single-vendor stack has its own trade-offs.
Beyond the demo, where do AI voice agents actually get used? This guide walks through the practical, real-world applications teams are running today — customer support, sales, appointments, order status, collections, and more — and what makes each one a good fit.
A "delivered" text or a call that connects on the first try depends on layers most teams never see — signaling protocols, carrier interconnects, failover routing, and delivery receipts that reflect the network, not just the API. Here is how SMS and voice infrastructure is actually built, where it commonly breaks, and how Orbit's own softswitch and messaging stack are put together.
A WhatsApp AI voice agent answers or places phone calls inside WhatsApp itself, using WhatsApp's Business Calling API plus a real-time speech-to-text, language-model, and text-to-speech pipeline. Here is exactly how that call flow works, which countries support it, real use cases, and how to launch one.
The WhatsApp Business API is not the free WhatsApp Business app — it is a programmatic messaging platform built on a WABA, message templates, and a 24-hour session window, accessed through Meta's Cloud API or a Business Solution Provider. Here is how each piece works and how they fit together.
Separate point solutions for SMS, WhatsApp, voice, and AI agents each carry their own contract, markup, and integration cost that a per-channel price sheet never shows. Here is a component-by-component cost breakdown and a framework for modeling the ROI before you commit budget.
A traditional IVR routes callers through a fixed "press 1 for sales" menu tree; an AI voice agent understands free speech and reasons over live data instead. Here is a technical, operational comparison of the two approaches, and how to modernize an existing IVR without a rip-and-replace.
Most CPaaS vendors claim a "direct carrier network," but the ownership models behind that claim differ enormously — from an FCC-licensed carrier to a privately-owned IP backbone to a large aggregator built by acquisition. Here is a neutral, sourced framework for telling them apart, plus what each major vendor states about its own network.
A voice AI vendor's headline per-minute rate almost never includes the LLM, speech-to-text, text-to-speech, and telephony costs stacked on top of it. Here is what independent testing finds the real all-in cost actually is, plus an interactive calculator to estimate your own stack.
Most "WhatsApp API pricing" guides quote Meta's own per-message rate and stop there, without saying whether your BSP is adding a markup on top of it. Here is how Meta's conversation/message pricing works, how BSP markup is typically structured, and what a genuine zero-markup, bring-your-own-account model looks like.
Artificially Inflated Traffic (AIT) — fraudulent A2P SMS traffic generated to earn termination revenue further down the delivery path — cost brands an estimated $2.4 billion between 2022 and 2024. Here is how AIT actually works, what it costs, and the concrete controls that stop it.
Voice biometrics verifies who is speaking; anti-spoofing detects whether the voice is even real. As AI voice cloning gets cheaper, CPaaS platforms embedding both — not just speaker verification alone — are the ones actually defending against synthetic-voice fraud. Here is how the underlying models work.
RCS and WhatsApp are both rich, branded messaging channels for reaching customers beyond plain SMS, but they run over different networks with different reach and setup. Here is how RCS and WhatsApp compare, and how to decide which one — or both — fits your business.
Voice AI lets software understand and speak natural language on a phone call, so an AI voice agent can answer, qualify, and resolve calls without a human. Here is how voice AI works, where it meets messaging, and how Orbit runs AI agents across voice and every channel.
RCS Business Messaging upgrades SMS into a rich, branded, interactive channel — verified sender names, images and carousels, suggested replies, and read receipts, delivered over the carrier network. Here is how RCS works, how it compares to SMS, and how Orbit offers RCS as one of its messaging channels.
