Connect
Zero vs the JustCall to CRM bundle: keep your 3CX or switch?

If you run an agency CRM platform and you already have 3CX in place,
the choice in front of you is not “JustCall versus 3CX as phone
systems”. The choice is whether you replace 3CX with a JustCall plus CRM
integration bundle, or keep 3CX and add a purpose-built bridge. This
page lays out both options honestly.
TL;DR: The JustCall-to-CRM bundle is the right
answer if you want one vendor for cloud PBX, dialer features and the CRM
integration, and you are willing to retire 3CX. Connect Zero is the
right answer if you already have 3CX deployed and want to keep that
investment intact while still landing every call in your CRM. The
pricing shape is also different: per-user JustCall pricing with a
two-seat minimum versus flat per-location Connect Zero pricing.

Features
The JustCall-to-CRM bundle is a cloud PBX with a strong dialer story.
Power dialer and predictive dialer features live in the higher tiers,
alongside AI call scoring, real-time agent assist and sentiment analysis
at the top of the plan range. Local numbers in over seventy countries
cover most global agency needs. The CRM integration sits as a connector
inside this PBX product and is enabled at the Team tier and above.
Connect Zero is a bridge from 3CX into your CRM. It picks up 3CX call
events, matches the inbound caller against contacts in your CRM,
attaches the call recording to the contact and timeline, and fires
workflow triggers on the call outcome. 3CX continues to handle the PBX
work, including queues, IVR, business hours, voicemail and call
recording.
The shape-of-value question is the same as with any PBX bundle: do
you want the PBX features and the CRM integration in one vendor, or do
you want to keep your 3CX investment and add a bridge. Both are
legitimate answers for different agency profiles.
Pricing
JustCall publishes its rate card. The Team plan is USD 29 per user
per month with a two-seat minimum, so the entry point is USD 58 per
month before any add-ons. Importantly, the CRM integration is only
available from the Team plan upwards, which is sometimes not flagged on
the integration page itself. The Pro plan at USD 49 per user per month
unlocks the power dialer. The Pro Plus plan at USD 89 per user per month
adds AI call scoring and real-time agent assist.
Connect Zero publishes USD 39 per location per month flat. The number
does not change with team size and there is no per-seat fee. Call sync
is metered at USD 0.02 per inbound message synced and workflow triggers
at USD 0.01 per trigger fired.
Total cost consideration: At two seats on JustCall
Team, monthly cost is USD 58 plus any number rental and add-ons. At ten
seats it is USD 290. At twenty seats it is USD 580. Connect Zero stays
at USD 39 plus the per-call and per-trigger meter at every team size.
For agencies adding seats, the Connect Zero shape is materially cheaper
from two users upward.
Setup and onboarding
Standing up the JustCall bundle means signing up, picking your plan,
porting numbers, training agents on the JustCall soft-phone, configuring
the dialer if you use one, and enabling the CRM integration once you are
on Team plan or higher. The cutover is a project and the dialer
configuration in particular usually deserves dedicated time.
Adopting Connect Zero from the CRM marketplace takes about two
minutes. You install the app, paste in the 3CX webhook URL, finish the
OAuth handshake to the CRM, and the bridge is live. Your existing 3CX
queues, IVR and recordings continue to work because nothing about 3CX
changes.
Support
JustCall provides global support with multilingual coverage and a
documented response framework. The G2, Capterra and Trustpilot listings
give you a public read on customer sentiment.
Connect Zero provides Australian-hours support directly from the
Adelaide team. Smaller team, shorter chain, with the engineers who built
the bridge handling escalations. The trade-off is timezone coverage: if
your agency is North American and needs 9am US-Eastern support, the
JustCall bundle has wider hours.
Integrations
JustCall publishes a long integration list across CRMs, helpdesks and
other tools. The CRM integration sits inside this catalogue and is
enabled at the Team tier.
Connect Zero is purpose-built for the 3CX-to-CRM pair. It is not a
generic PBX-to-anything platform. If you need a broad cross-tool
integration catalogue, JustCall’s breadth is the right answer. If you
need 3CX into your CRM, Connect Zero is the focused answer.
Who the JustCall bundle
suits
The JustCall-to-CRM bundle is the right choice for agencies that:
- Are starting fresh with no incumbent phone system
- Want a strong dialer story with power or predictive dialing baked
in - Need AI call scoring or sentiment analysis at the top tier
- Are comfortable with the Team plan or higher to enable the CRM
integration - Have global teams that benefit from JustCall’s seventy-plus-country
local-number footprint
The ideal JustCall-bundle customer is a growth-stage sales agency
that wants the dialer features alongside the CRM integration and is
choosing a cloud PBX for the first time.
Who Connect Zero suits
Connect Zero is built for agencies that:
- Already run 3CX and have numbers, extensions, queues, IVR and
recordings configured - Do not want to retire the phone system to land the CRM
integration - Want flat per-location pricing rather than per-seat pricing
- Want every plan to include the full CRM integration, not just the
higher tiers - Prefer cancel-by-uninstall over annual contracts
- Are cost-sensitive from two users upward
The ideal Connect Zero customer is an agency already on 3CX with two
or more users and a CRM in place, looking to land every call on a
contact record without changing phones.
Bottom line
If you want a dialer-heavy cloud PBX with the CRM integration bundled
in, and you are happy on the Team plan or higher, the JustCall bundle is
a coherent choice. If you already have 3CX in place, Connect Zero keeps
the phone system, adds the CRM bridge in two minutes, and runs at a flat
per-location rate that does not scale with team size.

Frequently asked questions
Do I need
to retire 3CX to integrate it with my CRM?
No. Connect Zero is purpose-built so that you keep 3CX and bridge it
to your CRM alongside. Nothing about your 3CX configuration changes. The
bridge picks up call events, matches the caller, attaches the recording
and fires CRM triggers.
Is
the CRM integration available on every Connect Zero plan?
Yes. Connect Zero has one standard plan at USD 39 per location per
month and the full integration is on it. There is no Team-tier gate, no
Pro-tier gate and no add-on price for the CRM connector itself. Only the
per-call and per-workflow-trigger meter is variable.
What does
Connect Zero cost compared to JustCall?
Connect Zero is USD 39 per location per month flat plus the per-call
and per-trigger meter. JustCall Team is USD 29 per user per month with a
two-seat minimum, so JustCall starts at USD 58 per month and scales
linearly with seats. From two users upward, Connect Zero is materially
cheaper.
Will my call
recordings show up in the CRM?
Yes. 3CX recordings are attached to the matching contact record in
the CRM and appear on the contact timeline with a clickable link. The
recording attachment is included in the standard plan and there is no
separate storage charge.
Will workflow
triggers fire on inbound calls?
Yes. Connect Zero fires CRM workflow triggers based on call outcome,
so you can route missed calls into a follow-up sequence, tag new
contacts on first call, or kick off automations when a known contact
calls in.
How long does setup take?
About two minutes to install the app, paste in the 3CX webhook URL
and complete the CRM OAuth handshake. No number porting, no team
retraining, no dialer rebuild.
Is there a free trial?
Yes. The trial runs on your existing 3CX setup with no credit card
required to start. The trial window gives you enough time to see live
call events landing on contacts in the CRM.
What happens if I cancel?
You uninstall the app from the CRM marketplace. New calls stop
flowing into the CRM. Historical call events and recording links that
already landed in the CRM remain in the CRM. There is no written notice,
no minimum term and no exit fee.
Will
Connect Zero work for agencies with multi-tenant CRM setups?
Yes. Each CRM sub-account or location counts as one location in the
Connect Zero pricing model. The bridge supports multi-tenant
configurations where each client has their own sub-account.
Does Connect Zero
support 3CX from any host?
Yes. Connect Zero works with self-hosted 3CX, 3CX in the 3CX cloud,
and 3CX hosted by Australian or global partners. The webhook
configuration is the same regardless of host.
Is the
JustCall CRM integration really tier-gated?
The JustCall integration page for the agency CRM platform does not
always flag this clearly, but the integration is enabled from the Team
plan upward. If you are on a lower JustCall tier and you need the CRM
connector, you will need to upgrade. Connect Zero has no such gating
because the full bridge is included in the standard plan.
