You want more first meetings booked without hiring another sales development rep, and every AI SDR site says it can do that. The tools differ on four things: whether the agent talks to prospects on the phone or only sends email, who sets it up and keeps it running, how much volume the price includes, and what happens when you go past it.
We make Odyssey AI, so it is first on this list. Every other price and feature below is taken from the vendor's own pages on October 20, 2026. Odyssey AI is not affiliated with any other company named here.

How we compared them
Channel: phone calls, email, or both.
Who runs it: your team builds and maintains the agent in the vendor's software, or the vendor sets it up or runs it for you.
Price: the published starting price, and what it includes.
Volume: the minutes or leads included each month, and what happens when you use them up.
1. Odyssey AI: an AI SDR built and run for you
What it does: it places outbound calls from your list and holds a two-way conversation with whoever answers. It responds in under a second, and when a prospect cuts in, it stops and answers the question instead of finishing its sentence. It asks your qualifying questions, books the meeting on your calendar while the prospect is still on the phone, and sends the invite before the call ends. When a prospect wants a person, it transfers the live call to a rep; if no rep picks up, it comes back to the prospect and books a time. It follows up by email when your rules say to.
What it writes to your CRM: every call writes the same records, whether it ended in a meeting or at a disconnected number:
- the call, matched to the contact it dialed, with an outcome from your own list
- the answers to your qualifying questions, in their own fields, so you can filter and count them
- a summary note, the recording and the transcript
- the next step: the booked meeting, a callback task for a rep, or the follow-up email
- any do-not-call request, so nobody dials that number again
Who runs it: we build it around your call list, your qualifying questions, your calendar and your CRM. The rules are written in plain language: who to call, the opening, what earns a meeting, calling hours, and what the agent will not discuss. After launch we run it: monitoring, fixes and the changes you ask for. When a prospect asks whether they are talking to an AI, it says yes.
Where it has worked: since December 2025 it has placed more than 30,000 outbound calls, most of them for an oil and gas company, qualifying prospects and setting meetings.
How long a build takes: a simple build can be ready in a few days. A complicated one can take 90 days to design, build and test.
Price: a build fee from $5,000, then from $500 a month, including 500 connected minutes of talk time and the activities it logs to your CRM. The monthly fee covers AI model usage, the phone line and call minutes, monitoring and fixes, and the changes you ask for. A campaign that goes past its contracted volume can be billed by the minute. More systems to connect, more volume and more complex rules raise a quote.
Fits: a sales team, an operations team or an owner who wants calls made and meetings booked without running the software.
2. ColdCalls.ai
What it does: an AI caller that dials your list, qualifies prospects, books meetings with a calendar invite and syncs each call to your CRM. Every call is transcribed, and recording is an option on each seat. Its pages do not describe transferring a live call to a person.
Who runs it: its pricing page says its team sets up each campaign and reviews it for compliance before the first dial.
Price: Starter is $499 a month per seat, or $249.50 a month billed yearly, for 250 connected minutes, with a limit of 25 connected minutes a day. Growth is $1,490 a month for three seats and 800 minutes. Scale is $3,900 a month for 10 seats and 2,000 minutes. The minutes reset each billing period. Billing is monthly, you can cancel at any time, and there is no free plan.
Fits: a team that wants a phone SDR set up for it and has a steady, modest number of conversations each day.
3. Autocalls.ai
What it does: a self-serve AI phone agent with outbound call campaigns, appointment booking, transfer to a person, and retries when a call reaches voicemail. It can also send email and text messages, and it connects to a CRM through automations.
Who runs it: you do. You build the agent in its no-code editor.
Price: Starter shows $27 a month next to a struck-through $34, for 120 minutes, one campaign and three calls at a time. Pro shows $103 next to $129, for 700 minutes, five campaigns and 10 calls at a time. Extra minutes cost $0.20 on Starter and $0.16 on Pro. There is no setup fee, every plan can be cancelled monthly, and there is no free trial.
Fits: a small team or an agency that wants to build its own calling agent at a low monthly cost.
4. Famulor
What it does: an AI phone agent platform with outbound call campaigns, appointment booking, and transfer to a person, cold or warm. It also sends email, text and WhatsApp messages.
Who runs it: you do, in its no-code flow builder. Its pricing page lists no onboarding costs.
Price: pay as you go is €0.15 a minute, with nothing to pay up front. Plus is €27 a month billed yearly for 100 minutes, with extra minutes at €0.13. Pro is €103 a month for 667 minutes. Plans run one to five calls at a time, and syncing calls to a CRM is an add-on below the Agency plan. Prices are in euros.
Fits: a team that is comfortable configuring its own agent and pays in euros.
5. Phonely
What it does: an AI phone agent built first to answer calls, with appointment booking and warm transfer to a person. Its FAQ puts outbound calling on the Pro plan.
Who runs it: you do, on the self-serve plans. Its Enterprise plan includes building the agent for you.
Price: Pro is $150 a month, or $100 a month billed yearly. Its plan card says 650 minutes, and the comparison table on the same page says 750. Extra minutes on Pro cost $0.30. Starter is $50 a month, and a free plan includes 100 minutes.
Fits: a business that mainly needs its calls answered and wants some outbound calling on the same plan.
6. SDRs.ai
What it does: an AI SDR that starts with email. The Pro and Enterprise plans add an AI voice agent that calls your prospects, and every call is recorded and transcribed. It syncs both ways with a CRM. From the Plus plan up, its sequences add LinkedIn and X messages: it writes each one, and you send it from your own account.
Who runs it: you do. Sign-up is self-serve, with no setup fee and no required sales call.
Price: Pro, the first plan with calls, is $499 a month, or $249 a month billed yearly ($2,988 a year). Plans are sized by leads per day, not minutes. When you reach the limit, the AI features pause until the first of the next month.
Fits: a team that already prospects by email and wants to add calls.
7. Salesforge (Agent Frank)
What it does: an AI SDR for email and LinkedIn prospecting. Its pages do not list phone calls.
Who runs it: Agent Frank is available only after a demo with Salesforge's team, and an account manager helps set it up.
Price: $599 a month billed quarterly, or $499 a month billed annually. There is no free trial.
Fits: a team whose prospects answer email and LinkedIn messages, and that does not need calls made.
What 1,000 minutes a month costs
A starting price tells you what the smallest plan costs. Here is what 1,000 minutes of calls a month costs on each phone tool, from the same pricing pages:
- ColdCalls.ai: more than the Growth plan's 800 minutes, so the Scale plan: $3,900 a month, or $1,950 a month billed yearly. Its pricing page does not list a price for extra minutes.
- Autocalls.ai: Pro's 700 minutes plus 300 extra minutes at $0.16, about $151 a month.
- Famulor: €150 a month, pay as you go.
- Phonely: Pro plus extra minutes at $0.30, about $225 to $255 a month, depending on which of its two minute figures applies.
- Odyssey AI: $500 a month includes 500 connected minutes, and a contract for 1,000 minutes is quoted. The build fee is from $5,000.
SDRs.ai and Salesforge price by leads and contacts, not minutes, so they are not in this list.
What the per-minute price leaves out
What counts as a minute: ask whether a plan counts connected minutes, every minute a line is open, or each call rounded up to a whole minute. Most cold calls are short, so the answer changes how far a bundle goes.
Setup and upkeep: with a self-serve tool, your team writes the script, loads the list, connects the calendar and the CRM, and changes the agent when it handles a call badly. That work is a large part of the difference between a $27 plan and an agent someone builds and runs for you.
Transfers: when a prospect is ready to talk, the agent should be able to hand the call to a rep while they are still on the line. Odyssey, Autocalls.ai, Famulor and Phonely list a live transfer. ColdCalls.ai's pages do not mention one.
Where the calls are logged: a booked meeting is only useful if your reps can see what was said. Check whether each call's outcome, answers and notes reach your CRM, and who sets that up.
Questions to ask any AI SDR vendor
- What counts as a minute, and what happens when the month's minutes run out: extra-minute charges, a pause, or an upgrade?
- Who writes the script, and who changes it after a call goes badly?
- Can the agent transfer a live call to one of your reps?
- What does each call write to your CRM, and into which fields?
- How does it handle do-not-call requests and calling hours?
- What does the agent say when a prospect asks whether it is an AI?
- Can you hear calls from a live deployment before you sign?
How to choose
If you prospect mainly by email, SDRs.ai and Salesforge are built for that. If you want to build and run a calling agent yourself and your volume is small, the minute bundles from Autocalls.ai, Famulor and Phonely cost the least to start. ColdCalls.ai sits between the two: a phone SDR its team sets up, priced per seat with a daily minute limit.
If you want the calls made, the meetings booked and the CRM kept up to date without your team running the software, that is what Odyssey builds. You tell us who to call and what a qualified prospect looks like; we build the agent, run it and change it as you learn what works.
Start with your call list
Odyssey builds and runs the AI cold caller from our office in Colleyville, Texas, in the Dallas-Fort Worth area, for businesses across the United States. If you have a call list and a team that cannot get to all of it, book a call and we will go through your list, your qualifying questions and your CRM.
