Trellus is an embedded power and parallel dialer that runs as a Chrome extension inside the CRM or sales platform you already use, with public individual pricing and live AI coaching. If you want more lines per rep, a real reply to AI call screeners instead of a recorded clip, and numbers checked with the carrier before you dial, here are the strongest Trellus alternatives for outbound teams in 2026, starting with our pick.
TwinsAI dials up to 8 lines at once, validates every number with the carrier before the dial, and uses ScreenPass to reply to AI call screeners with the caller's real name and reason. Once a human answers, your rep is on the line in under 450ms. It works with HubSpot, Salesforce, Close, Attio, Outreach, Zoho, HighLevel, and there is no seat minimum.

Parallel dialing plus AI screener handling means your reps drop into live conversations only, with more live conversations per hour than industry-standard single-line dialing.
Most dialers: Industry connect rates sit around 3 to 5%, and most pickups die in the bridge or on an AI screener before a human says hello.
When an AI call screener answers, ScreenPass replies to its question with the caller's real name and reason for calling, on iPhone and Android, and patches the prospect to your rep once a human is detected.
Most dialers: Hang up on the screener, or play the same pre-recorded introduction to every screener and wait.
From the moment our detector confirms a human voice, your rep is bridged in under 450ms, well inside the ~700ms hang-up threshold, so the prospect never hears the seam.
Most dialers: Parallel dialing's 1 to 3 second connect pause is the robocall tell, and it lands above the ~700ms hang-up threshold.
TwinsAI validates each phone number with the telecom carrier before dialing, so your parallel lines are not spent on dead or disconnected numbers.
Most dialers: Dial whatever is in the list and let the rep find out which numbers are dead.
Trellus and TwinsAI both dial in parallel and both work with the CRMs most outbound teams run on. Trellus leads with an in-CRM Chrome extension, public pricing, and a wide integration list. TwinsAI leads with more lines per rep, a real reply to AI call screeners, carrier-checked numbers, and a fast human handoff.
We tried to be fair. Trellus details come from trellus.ai (pricing, integrations, dialer, and HubSpot pages) as checked on October 22, 2026. Trellus says line counts and features vary by plan and platform. Got something wrong? Tell us, we'll fix it.
Both tools get reps dialing more numbers. These are the three places a call block plays out differently, with the Trellus side described in Trellus's own terms.
More mobile calls now hit an AI call screener first: about 28% of mobile calls are now answered by an AI call screener, based on TwinsAI's own call data (2026), and the share is rising. Trellus lets a rep pick a recorded introduction that plays when a supported screener asks, on parallel calls with a Trellus number, and its dialer FAQ notes the recording does not hold a conversation. ScreenPass replies to the screener's actual question with the caller's real name and reason, set by a prompt you control, and patches the prospect to your rep once a human is on the line.
Parallel dialing works by stacking attempts so a rep spends less time listening to rings. Trellus lists up to five simultaneous lines on eligible plans. TwinsAI runs up to 8 lines per rep on Enterprise and up to 4 on Scale, so a rep on the top plan works more of the list in every round of dials.
Trellus focuses on your side of the call: it ranks likely pickups with Hot Numbers (a beta feature), picks a caller ID, and flags numbers with spam signals. TwinsAI checks the other side: every prospect number is validated with the telecom carrier before it is dialed, so lines are not spent on dead or disconnected numbers. Many teams will want both jobs done, so ask each vendor how it handles the other.
Bring a real list. We'll dial it in parallel, show ScreenPass replying to an AI call screener, and patch a live human to your rep.
