8x8 alternatives for UK businesses.

The savings.

Annual cost on 8x8 X2 (the typical UK SME tier) versus managed 3CX at three sizes. X4 customers (£32/user) save more.

8x8 X2 UK list (£22/user/mo). 3CX figures include licence + UK hosting + SIP + support. Ex-VAT. See honest pricing.

What stays the same.

• Voice calling to UK landlines and mobiles. 3CX via UK Gamma SIP supports all UK numbers. Outbound rates per minute are typically lower per minute than 8x8 includes in their unlimited bundle, but you pay for what you use. For typical SME usage (~30 mins/user/day) variable cost is trivial.
• Video conferencing. 3CX PRO has integrated video; AI tier supports up to 250 participants. Comparable to 8x8 Work video.
• Team chat and messaging. 3CX has built-in chat. Most firms run team chat in Teams or Slack regardless, so the 8x8 chat module sometimes goes unused — worth checking what your team actually uses before treating it as a switching cost.
• Call recording. 3CX PRO includes recording with retention controls.
• Mobile apps. 3CX iOS and Android apps cover the same use cases as 8x8 Work mobile.

What changes.

• Per-user-for-life economics replaced by per-system. The biggest structural change. Growth doesn't add £22/user every time you hire.
• UK partner relationship instead of US-based queue. You get one UK contact across licence, hosting, SIP, handsets, training, and support.
• UK-hosted recordings. If you've been on 8x8's EU regions, your recordings move to UK hosting.
• SIP usage shows as a separate line item. Some firms prefer the bundled "unlimited" feel of 8x8. We're transparent about SIP usage; we'll bundle into a flat monthly figure if you prefer.

When to stay on 8x8.

• You're on X6 or X8 for genuine contact-centre operations. 8x8's contact centre is strong. 3CX AI tier is capable but not a peer for 20+ agent inbound queues with skills routing, WFM, and omnichannel.
• You have heavy outbound calling (200+ mins/user/day) and the unlimited bundle is genuinely earning its keep. At very high outbound volume, 8x8's unlimited-UK becomes meaningful. Rare for typical SMEs.
• Under 10 users and the saving is £40–80/month. May not be worth the project.

Switching mechanics — 8x8-specific points.

1. Week 1 — audit. We look at your 8x8 invoice (X-tier, user count, any add-ons), call volumes, current number routing. Quote on the honest-pricing template.
2. Week 2–3 — 3CX provisioning. UK hosting, Gamma SIP, handsets ordered, IVR rebuilt from your current 8x8 setup.
3. Week 3–5 — number porting. 8x8 UK numbers port out cleanly via standard LoA. The carrier behind 8x8 UK numbers varies; some go through Gamma directly (clean), some through other UK carriers (3–4 week port). Plan for the longer timeline.
4. Week 5–6 — training and cut-over. Half-day training. Cut-over weekend, usually Friday evening.
5. Week 7+ — 8x8 contract wind-down. 8x8 contracts typically run 36 months. Time the cut-over to align with renewal; if renewal is months out, calculate whether the early-termination fee is offset by switching savings (usually yes above 40 users).

What about 8x8 Work-specific integrations?

Three common 8x8 integrations and what happens to them:

• HubSpot, Salesforce, Dynamics, Zendesk: 3CX PRO has integrations with all of these. Click-to-call, screen-pop, call logging — parity. Rebuilding the workflow is a few hours of setup time during week 3–5.
• 8x8 Frontdesk / receptionist app: 3CX has its own switchboard / reception console that does the same job. Train reception on the new UI; takes 30 minutes.
• 8x8 Contact Center (X6/X8): if you're using this seriously, it's the case where you don't switch — see "When to stay" above. If you're paying for it but not using it, the audit usually surfaces this; switching saves the X6/X8 tier premium on top of the base savings.

Common questions from 8x8 leavers.

What about international calling?

3CX via Gamma supports calling to 200+ international destinations at competitive per-minute rates. Specific country rates vary; we'll model your specific international usage at audit.

Will my admin team need retraining?

3CX admin is different from 8x8 admin but not harder. We handle the day-to-day changes (add a user, modify a queue, update IVR routing) as part of the managed service. Your admin team is involved on strategic changes only.

What about reporting and analytics?

3CX PRO includes call reporting (call volumes, queue performance, agent activity, wallboards). 3CX AI tier adds advanced analytics. For most SME reporting needs PRO is sufficient; if you actively used 8x8 X4's supervisor analytics, AI tier matches it.

Can my reception staff handle the new switchboard?

Yes. 3CX's switchboard is drag-to-transfer with extension state at a glance — same conceptual model as 8x8 Frontdesk. Half-hour training session is enough.
