3 KrispCall Alternatives for Team Calling and AI Agents
Consider Carly when you want an AI agent to handle calls and appointments, JustCall for a staff calling platform, and Aircall for a team evaluating a dedicated business phone system. Keep KrispCall on the shortlist if employees like its calling workflow and its current destination rates fit your traffic.
The important distinction is who takes the call. Software that helps an employee dial, summarize or review a conversation is different from an AI receptionist that speaks with the caller and follows business rules. Both can be valuable, but they should not be priced or evaluated as interchangeable capabilities.
This guide is published by Carly. We checked public plans and original customer feedback on November 9, 2026. We have not measured call quality, uptime or comparative AI accuracy. The trial cases below describe what a buyer should verify.
A KrispCall customer praised calling while noting a learning curve
Akshay N., a small-business director of sales, gave KrispCall 5/5 in an organic G2 review dated September 17, 2026. He praised setup, shared history and his calling experience between India and the US, but wrote: “The dashboard takes a bit of getting used to”.
That is a modest usability criticism from a satisfied customer, not evidence of broadly poor call quality. His experience on a particular route also does not establish quality for your network, country or devices.
Use the review to design a realistic trial. Have an employee who will actually answer calls find a customer, make a call, review the history and continue the conversation the next day. A vendor-led tour will not show how quickly your team becomes comfortable with the interface.
KrispCall pricing: separate seats from traffic
The KrispCall pricing page lists Starter at $15 per user/month monthly or $12 annually, Advance at $40 or $32, and Max at $60 or $48. Starter supports up to five users and Advance up to 50; Max has no user cap. The page lists one US, UK or Canadian number per user.
Starter and Advance use pay-as-you-go calling and SMS. Max includes specified allowances under fair-use terms: 2,000 outgoing and 2,000 incoming minutes per user for eligible routes, plus 1,000 US/Canada SMS segments. Do not describe every plan as having the same usage model.
For three people on monthly Starter, seats total $45 before usage and other applicable charges. The same seat count on monthly Max totals $180. These are calculated subscription examples, not complete bills. The right choice depends on actual destinations, direction and volume.
Ask for rates using the routes your staff calls. A local customer-service line and an international outbound team can have very different costs even with the same number of employees.
AI assistance and an AI voice agent are separate questions
When checked, KrispCall’s site navigation labeled its AI Voice Agent “Coming Soon,” while listing other AI capabilities such as Copilot. That is a dated public-page observation, not a claim that every AI feature is unavailable. Confirm the voice agent’s current availability and terms directly if it is essential to your purchase.
Do not infer autonomous answering from call summaries, suggested replies or other assistance features. Ask to place a call to the proposed agent, give it a realistic request and inspect the outcome. The same standard should apply to Carly and every other vendor.
Three alternatives by who does the work
| Alternative | Best reason to evaluate | Main purchase question |
|---|---|---|
| Carly | AI handles conversations and appointment work | Can it follow your rules, book correctly and escalate? |
| JustCall | Employees need a calling and messaging platform | Which plan covers the required staff workflow and routes? |
| Aircall | A team wants a dedicated phone system | Minimum licenses, calling scope and any separate AI offering |
1. Carly: when the phone should be answered while the team is busy
Carly provides AI agents that can handle phone and messaging work alongside email and calendars. Its strengths include customizable rules, email labeling and sorting, advanced calendar work, phone and SMS. Carly connects to thousands of apps and works inside ChatGPT, Claude, Grok Bot, Meta Muse and Perplexity.
Imagine an owner serving a customer when another person calls about an introductory appointment. The useful assignment is specific: answer from approved business information, collect the necessary details, offer appropriate times and leave context for the owner. An unusual request should reach a person rather than receive an improvised promise.
For the first demonstration, choose one appointment type. Define the service area, hours, duration, calendar and escalation rules. Give the agent examples of what it may say about pricing and what requires approval.
Then test more than the easy call. Interrupt the agent, change the requested date, ask a question outside the approved information and request a person. Inspect the final booking and notes. A pleasant voice is useful, but the business outcome matters more.
Carly costs and limits for a phone-system buyer
Free Zapier-style workflows; AI agents from $35/month. Organization seats are $35 per seat/month. Business calling, SMS and the AI receptionist are separately billed add-ons. Include the appropriate AI usage tier and communications charges in the estimate.
This is not a $35 all-inclusive phone service. Request a complete quote for expected call minutes, messages, numbers, users and agent work. Confirm the availability of your required numbers and destinations rather than assuming that one country’s setup applies everywhere.
Carly is also not a blanket replacement for every staffed phone-system requirement. If supervisors need a particular queue, dialer, monitoring feature or report, have it demonstrated explicitly. A business may keep its staff calling platform and use an assistant for a bounded task, provided the proposed routing and handoff are verified.
The phone and email overview explains Carly’s broader communications setup. For this purchase, keep the trial centered on the call and the work that follows it.
2. JustCall: when employees are still making most calls
JustCall pricing lists annual-billed Team at $29 per user/month, Pro at $49 and Pro Plus at $89. Its AI Voice Agent is separate from the staff plan. Check the calling destinations, allowances and messaging terms for the configuration you need.
JustCall is a candidate when the day-to-day work is employees calling customers, following up and recording outcomes. The right demonstration should use the employee’s actual process, not only a sample call placed from an empty account.
Ask a representative to work through several customer records, make an unanswered call, receive a callback and send the next message. Then have a colleague continue the conversation. Inspect what history and ownership information is available at each step.
If management requires coaching or supervision capabilities, name the exact feature and verify its plan. If the company wants an AI to answer calls independently, evaluate the separate voice offering with the same exception cases used for Carly.
This avoids a common comparison error: choosing the cheapest human-seat price for one vendor and the complete AI setup price for another. Our JustCall alternatives guide separates those buying paths in more detail.
3. Aircall: when a dedicated team phone system is the requirement
Aircall’s pricing lists Essentials at $30 per license/month annually and Professional at $50, with a three-license minimum. The minimum Essentials seat purchase therefore illustrates $90/month before other charges. Its separate AI offering has its own pricing and should not be assumed included in that seat total.
Aircall deserves evaluation when the business is buying a phone system for a team rather than a single personal line. Confirm the required routing, integrations, staff controls and reporting on the proposed plan.
Use an incoming call that needs a transfer. The first employee should capture context, the second should understand why the person is calling, and the final record should make the outcome clear. Add an unavailable employee and an after-hours call to expose the fallback behavior.
The license minimum is particularly relevant to a solo business or a two-person team. A product can be a good operational fit while its minimum purchase exceeds your needs. Larger teams should focus on the complete configuration rather than treating the minimum as the decisive factor.
The Aircall alternatives comparison covers the distinction between team telephony and delegated AI conversations. If KrispCall’s staff workflow already works well, require a concrete reason to rebuild it.
Test the routes and devices you actually use
Call quality depends on more than a vendor’s feature page. During your own trial, use the locations, networks, headsets and destination countries your staff relies on. Include incoming and outgoing calls, not just one successful internal test.
Record what happened without turning a tiny sample into a reliability ranking. Note dropped audio, confusing transfers, missed notifications and the steps required to recover. Ask the vendor to investigate reproducible issues before deciding they are inherent to the platform.
For AI calls, add business accuracy to the record. Did the agent use approved information? Did it choose an available appointment? Did it stop and escalate when the caller requested something outside its instructions? These checks evaluate a different risk from audio quality.
Plan the number move and fallback before cutover
Confirm the receiving vendor can support the existing number and its required calling and messaging capabilities. Agree on the transfer sequence and keep the old account active until the move is confirmed. A contact import does not mean the telephone number has moved.
Document the fallback route for calls during the transition. Staff should know where missed calls and voicemail will appear, who checks them and how customers are contacted back. Preserve required history and review scheduled follow-up messages so they do not fire twice.
For an AI receptionist, begin with a bounded appointment workflow and inspect real outcomes before expanding its responsibilities. Bring one ordinary call and one exception to a Carly setup call, and ask to see the booking, notes and human handoff at the end.
Test an AI receptionist on a real business call
Bring your approved answers, calendar and escalation rules, then inspect the complete outcome.
Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.
# Connect Carly Teams to an AI app
> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.
MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)
## Setup
Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.
1. Add Carly Teams:
- ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
- Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
- Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
- Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
- Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
- Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
Sign in with the Carly account that belongs to the organization.
2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.
3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.
4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.
## Email, calendars and workflows
Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.Want Carly answering your phones?
