Ring4

Ring4 describes itself as a shared business phone number for teams, with calls, texts and voicemails in one shared inbox. An AI receptionist answers when no one is available, captures leads and creates transcripts, summaries and action items, and commitments made on calls can be assigned to team members.

Website text messaging is included, and daily spam-label checks and remediation are part of the offer, with AT&T, Verizon and T-Mobile named on the homepage. Two business tiers are published per user per month on annual billing, plus a standalone spam monitoring app. The homepage shows no owner, parent company, country or postal address, so the country is not stated by the vendor. It names no app and refers only to business phone on any device.

• Shared business number. One number serves a whole team, with calls, texts and voicemails collected in a shared inbox so nobody works from a personal line.
• AI receptionist. It answers when no one is free, captures leads and writes transcripts, summaries and action items. Business includes 50 answers a month, then $0.60 per call.
• Assigned commitments. Promises made on calls can be assigned to team members, which turns a conversation into a task without retyping notes.
• Website text messaging. Texting from a website is included in the offer. The pages we read do not describe its widget or how conversations arrive.
• Spam label monitoring. Daily spam-label checks and remediation are included, with AT&T, Verizon and T-Mobile named. A standalone spam monitoring app starts from $9.99 a month, with the first check free.
• Call recording as an add-on. Call recording is listed at $5 per number. Extra numbers are $5 each on Business, and extra Personal numbers are $15 a month.
• Business Plus. Business Plus adds custom AI voice agents, phone support, an account manager and volume discounts, and starts at five seats.

• Small teams sharing one line. A shared inbox lets several people answer one number and see the same history, which suits a service business without a reception desk.
• Businesses missing calls out of hours. The AI receptionist answers when nobody is available and logs leads and summaries, with 50 answers a month included on Business.
• Outbound teams worried about spam labels. Daily spam-label checks and remediation target the problem of numbers flagged as spam, a topic the homepage ties to AT&T, Verizon and T-Mobile.

The pricing page lists a 7-day free trial for the Business plan, which costs $19 per user per month billed annually ($228 a year). Create an account, set up the shared number, and invite team members to the shared inbox. The help centre has an article titled How do I create a Ring4 Personal 2nd line account for personal lines, and another on whether Ring4 supports service in India or Bangladesh, so check country coverage first.

Add numbers at $5 each, and call recording at $5 per number if needed. The homepage names no app and refers only to business phone on any device, so confirm which device options exist. The homepage shows $24 per user per month while the pricing page lists $19, so confirm the figure at sign-up.

Ring4 pitches one shared number where a team sees calls, texts and voicemail in a single inbox. Business covers one number; extra numbers and call recording are separate line items, and the AI receptionist includes 50 answers a month before per-call charges.

The homepage price differs from the pricing page, so confirm the figure before buying. Neither page shows an owner, a country or a postal address.

The virtual phone number apps list places Ring4 6 of 13: it follows Onoff and comes before CallHippo. Challengers hold places 1 to 3 where a category has them; the number here is a place in the order, not a mark out of ten.

The vendor states no country of establishment, so Ring4 is left out of the regional count for this list.

In the catalogue: Per user per month on annual billing, two tiers published; 7-day trial; extra numbers and recording priced apart.

The Business plan is $19 per user per month billed annually ($228 a year), with a 7-day free trial. Business Plus is $24 per user per month billed annually ($288 a year), starts at five seats and adds custom AI voice agents, phone support, an account manager and volume discounts. Business includes one number, with additional numbers at $5 each, 50 AI Receptionist answers a month then $0.60 per call, and unlimited AI knowledge base articles. Call recording is $5 per number and extra Personal numbers are $15 a month. The standalone spam monitoring app is from $9.99 a month, with the first check free. The homepage shows $24 per user per month, while the pricing page lists $19 for Business billed annually, so the two pages differ.

Commitments made on calls can be assigned to colleagues.

Daily spam-label checks are included, and the homepage names three US carriers.

The homepage shows no owner, parent company, country or postal address for the company, and support is by email and phone.

• Zadarma (#2 of 13): Cloud telephony with virtual numbers in 110 countries and a built-in CRM. Watch out: the about page lists three office entities and no registered office, so the contracting party is unclear.
• Burner (#3 of 13): Second-number app from Los Angeles with number limits per platform. Watch out: an existing number cannot be moved into the app. (United States)
• MySudo (#4 of 13): Separate digital identities for calls, texts, email and payments. Watch out: minutes and messages are capped on SudoGo and SudoPro, so a busy line runs out.
