The two products in one sentence
Auto Attendant: one business number, a spoken menu of up to seven options, and forwarding to existing mobiles for $29/month for the company. It handles incoming calls, including a closed message after hours and voicemail by email, but does not place outgoing calls, send texts, record conversations or provide desk phones or apps.
Vonage Business: Vonage Business provides a managed business calling identity on apps or desk phones, with more administration than an incoming menu.
What the vendor publishes
Menu-plan price: Mobile: $19.99/line/month; standard rate for 1–4 lines, monthly plan.1
Is an installed app required to take calls? Not if you use a desk phone on Premium.1
Vonage calls its menu a Virtual Receptionist and documents menus with schedules, recorded or text-to-speech greetings and after-hours routing.2
Vonage prices Mobile per line in bands: $19.99 standard or $13.99 promotional for 1–4 lines, $17.99 or $12.59 for 5–19, and $14.99 or $10.49 for 20–99; above 99 it asks you to contact sales. Taxes and fees are extra.1
The 30% promotion applies to annual contracts only: Vonage requires a minimum 1-year contract for new annual accounts, with early termination fees of up to the total contract price, and states the offer is valid through 30 December 2026. Its monthly plan is charged at the standard rate with no early termination fee.1
The plan comparison ticks the Virtual Receptionist on Mobile, Premium and Advanced; desk phones start at Premium and Call Groups (simultaneous ringing) are on Advanced only.1
Vonage lists mobile and desktop apps, unlimited domestic calling and an Admin Portal on every plan.1
What one, three, five and seven people cost
The menu-capable plan used here is Mobile: $19.99 per line per month, standard rate for 1–4 lines, monthly plan.1 These are subscription examples in USD, before any applicable taxes, fees or separately charged usage. Our $29 is billed monthly; an annual-billing figure is a monthly equivalent of a longer commitment.
| People receiving calls | Vonage Business monthly equivalent | Auto Attendant monthly |
|---|---|---|
| 1 | $19.99 (1 × $19.99) | $29 |
| 3 | $59.97 (3 × $19.99) | $29 |
At 2 people, this published plan first exceeds $29/month on the stated billing basis. This is a price crossover, not a claim that the products provide the same functions.
Auto Attendant has no per-person charge: its up to seven menu options each ring up to three phones in turn, so the same $29 covers every person who answers.
The figures use the $19.99 standard rate for 1–4 lines; from five lines the rate falls to $17.99, so larger teams are not shown. On a one-year contract the promotional rate is $13.99 per line for 1–4 lines while the offer lasts.
How a call reaches your team: Vonage Business and Auto Attendant
The practical difference is where the work happens. With Auto Attendant, a caller dials one business number, hears a spoken menu, presses a key and the call rings the chosen person's own mobile (or up to three phones in turn) as an ordinary incoming call showing the business number; nobody installs an app, and the team keeps its existing mobile plans. How it works shows the whole path, and the auto attendant and IVR glossary entries separate a simple keypad menu from a full interactive voice response system.
- Who answers: on whether Vonage Business needs an installed app to take calls, the cited source says: not if you use a desk phone on Premium.1 Auto Attendant rings the phones people already carry.
- How it is billed: Vonage Business prices the cited plan per line, so the monthly bill grows with every person who needs to receive calls.1 Auto Attendant is one $29 monthly charge for the company.
- What the menu can do: compare the routing options in the facts above with the call routing Auto Attendant offers; Vonage Business's tools may be broader, and the question is whether you will configure and pay for the extra breadth.
- What Auto Attendant leaves out: it handles incoming calls only, so it does not place outgoing calls, send or receive texts, record conversations, ring several phones at once or provide queues; those belong to full platforms such as Vonage Business, compared in general on auto attendant vs VoIP platforms.
Questions to ask Vonage Business before you buy
Plan names and entitlements change often, so treat the page you read as a snapshot and put these questions to Vonage Business before you sign. The answers decide whether the comparison on this page still holds.
- Which plan includes the phone menu, and is the quote for that plan? The figures use the $19.99 standard rate for 1–4 lines; from five lines the rate falls to $17.99, so larger teams are not shown. On a one-year contract the promotional rate is $13.99 per line for 1–4 lines while the offer lasts.
- Does every person who answers a call need a paid seat? The cited plan is priced per line; ask whether occasional call recipients can share a seat or must be licensed.
- What is the billing basis? The figure used here is standard rate for 1–4 lines, monthly plan; ask what the monthly-billing price is and whether the term auto-renews. Taxes, regulatory fees and any usage charges are normally extra.
- What happens when nobody answers? Test the fallback: a menu option that rings a mobile in a no-signal area should fall through to voicemail, not to a busy tone. The no-answer timeout and overflow entries define the terms, and the call queue and ring group guide shows an all-busy test.
- How is the existing number moved? Ask for the porting steps, the information you must supply and the expected interval; the rules below set the minimum for ordinary numbers.5 Our porting guide lists what to collect first.
- How is each user's emergency address set? See the checks below and our emergency calling page before putting any phone service in front of staff.
Emergency calling and number porting checks
Two federal rules apply to any phone service you buy, so ask Vonage Business how it meets them. First, emergency calls. Kari's Law requires a multi-line telephone system to be configured so that a user can dial 911 directly, without a prefix such as the digit 9, and to provide on-site notification of the call where the system can be configured to do so.3 The FCC's definition of a multi-line telephone system covers network and premises-based systems, including Centrex, VoIP and PBX, and defines a dispatchable location as the validated street address of the calling party plus the suite or similar detail needed to identify where they are.4 A hosted phone with several users is therefore a system to check for these points, whichever vendor it comes from. See the E911, MLTS and dispatchable location glossary entries.
Second, porting. Carriers required to port numbers must complete a simple wireline-to-wireline or intermodal port within one business day, and a non-simple port within four business days, unless the new provider or the customer asks for longer; ports involving interconnected VoIP service count as intermodal.5 That is a ceiling on carrier delay for ordinary numbers, not a promise about Vonage Business's own onboarding, so ask for the vendor's expected date in writing. Read the local number portability and letter of authorization definitions, and the porting-time article for realistic intervals.
What the flat $29 line gives you
The team’s outbound calls stay on its current mobile plans, and one flat monthly charge with no annual contract covers directing incoming callers. Calls ring as ordinary incoming calls; people use their own mobile plan and dialler, and nobody needs a seat or an app. You pick the number, write the menu in English, French or Spanish (or up to all three) and set business hours online in the app. Voicemails arrive by email with the MP3 attached, and the transcript follows in a second email, in the voicemail's own language. See the complete call path and the $29 plan.
