3 Kixie Alternatives for AI Calling and Sales Follow-Up
Carly is our Kixie alternative for businesses that want an AI agent to answer calls, call customers back, text and book appointments. Aircall and JustCall are worth comparing when your priority is a broader communications workspace for a sales or support team.
Kixie offers sales dialing, business SMS, routing and conversation intelligence. Its published multi-line dialer can call up to four leads at once, with AI Human Voice Detection described as an additional option. That is a distinct purchase from an assistant conducting a conversation for you.
Before switching, decide whether you want to increase the capacity of human callers, delegate certain calls to AI, or do both. The best trial will expose that distinction immediately.
This guide is Carly’s editorial comparison of public product information reviewed November 9, 2026. It does not claim measured differences in connection rates or call quality.
What Kixie reviews reveal about setup and support
Brian F.’s July 29, 2026 G2 review described SMS and authentication problems after years with several accounts, including the frustration that “I could not reach a real person.” Kixie’s Radek Lord responded, acknowledged a process breakdown and described outreach from customer success alongside platform and carrier work. That response is relevant context; the review does not establish an ongoing outage.
A different reviewer, Mike R., gave 4.5/5 on October 20, 2026. He praised efficient calling but wrote, “Setting up SMS can also take a bit of effort.” G2 marks that review incentivized through an invitation on the seller’s behalf.
Both accounts point to an evaluation that a demo call misses: activating messaging and getting help when access fails. Ask who owns onboarding, how your staff obtain support and what information an escalation requires. The right comparison is your actual number, destinations and CRM—not an assumption that another vendor cannot encounter carrier or account problems.
Compare dialer costs with agent costs
Kixie’s pricing page presents Professional, single-line and multi-line dialing options, but we could not verify a public dollar quote for the configuration from the page reviewed. The multi-line option reaches up to four leads at once; AI Human Voice Detection is listed as a premium add-on. Ask for the seat count, term and add-ons in writing.
Aircall’s pricing separately presents an AI-agent offer with a $99/month minimum and a calling-seat offer starting at $30 per license/month on the displayed annual option. These are different units of purchase. Confirm seat minimums and usage rather than adding the two headline numbers and treating the result as a quote.
For Carly, Organization seats start at $35 per seat/month, while business SMS, calling and the AI receptionist are separately billed add-ons. A representative making calls, a parallel dialer finding a live person and an AI conducting an appointment conversation each consume different resources. Price the same workload before deciding which is cheaper.
When a Kixie replacement is unnecessary
Keep Kixie if the team values its outbound calling workflow and the real gap is answering inbound inquiries after hours. Changing the whole dialer may disrupt lead queues, local numbers, coaching and CRM logging without addressing that gap more directly. Conversely, adding an AI receptionist does not solve a rep’s need to work a call list faster.
Write down two separate success measures: a rep reaches and records the intended contact; an assistant completes the customer’s requested next step. Then choose the tool for each. If one product handles both adequately, consolidation can help. If it does not, avoid forcing every conversation into one operating model merely to reduce the number of subscriptions.
Compare the caller and the workflow
| Alternative | Reason to evaluate it | Trial priority |
|---|---|---|
| Carly | AI handling of calls, texts and bookings with customer context | A complete customer request, including an exception |
| Aircall | Business communications with voice agents and team features | Routing, staff experience and AI-to-human handoff |
| JustCall | Sales and support calling with messaging and automation | Your team’s calling and follow-up process |
1. Carly: delegate a defined call outcome
Carly can answer and place calls from a business line, exchange texts, work on WhatsApp and book against a connected calendar. Its team CRM keeps records for the customers involved.
Give the agent an outcome that can be checked. For a new service inquiry, that might mean collecting the job details and booking a consultation. For an existing customer, it might mean confirming an appointment and recording a requested change. Define what the agent may explain and when it should ask a person for help.
You can operate Carly from ChatGPT, Claude, Grok Bot, Meta Muse or Perplexity, and it connects to thousands of apps. The advantage is a customizable assistant across the conversation and the administrative work around it.
Do not buy Carly on the assumption that it reproduces a high-volume parallel dialer. Buy it for the customer jobs you can demonstrate it completing. Free Zapier-style workflows; AI agents from $35/month. Organization starts at $35 per seat/month, with usage to evaluate for the intended calling workload.
Carly cost and scope: Business SMS, calling and the AI receptionist are Organization add-ons billed separately from seats. Confirm channel availability and expected AI usage. Evaluate your required reporting, permissions and migration path before replacing an established CRM or phone system.
2. Aircall: a broader business communications workspace
Aircall combines a business phone system with team features and AI voice agents. It belongs on the shortlist when routing, the staff calling experience and inbound coverage matter alongside outbound sales.
The plan comparison shows a three-license minimum for Essentials and Professional. Professional adds features including the Power Dialer and advanced analytics. A solo buyer should therefore compare the minimum commitment, not assume the per-license headline is the total bill. Its separately offered AI Voice Agents are another configuration to price.
For a mixed sales and support team, test a busy period: one person is unavailable, a customer needs a specialist and another caller wants an appointment. Check the information the next staff member sees and whether the eventual outcome is recorded in your CRM.
Tradeoff: buying a phone system and buying an agent to own an appointment conversation are different decisions. Compare both if you need both. Do not assume Kixie’s multi-line dialing has an exact equivalent on an entry Aircall plan. See Aircall alternatives for a wider phone-system comparison.
3. JustCall: calling and messaging for revenue teams
JustCall is another option for a team that alternates between calls and messages. Its product covers a phone system, AI features, coaching and automation, so it is relevant when managers need more than a way to place the next call.
JustCall’s pricing lists Team at $29, Pro at $49 and Pro Plus at $89 per user/month with annual billing. SalesPro has a separate custom quote. Call routes, message segments and AI-agent usage need attention beyond those seat prices; establish which allowances apply to your destinations.
Use one representative’s complete follow-up cycle: call, outcome, text, customer reply and the next task. Have the manager inspect both the communications activity and the CRM. The useful result is a record the next person can act on, not only a well-written transcript.
Tradeoff: a wider communications suite can require more configuration than a narrowly scoped dialer. Ask the people using it daily to perform the trial. A single administrator’s successful test call does not establish the team’s working experience. Our JustCall alternatives guide covers the broader category.
Use the same call scenarios for every finalist
Test a straightforward inquiry, a caller who interrupts, a request outside the service area and a reschedule. Include a human handoff and a customer who prefers text. Review the result in the CRM and calendar, not only in the phone dashboard.
Ask separately about number availability, your destinations, call recording settings and expected usage. Keep those requirements explicit when comparing quotes.
For Carly, start with business phone and messaging setup and give the agent one clear task before expanding its remit.

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?
