8x8 XCaaS platform overview
Verified 2026-09-24 · 54 sources · tier 1–3
Also known as 8x8 Platform for CX, XCaaS.
8x8 describes its 8x8 Platform for CX as combining contact center, business communications, and application programming interfaces 39. 8x8 announced its brand evolution toward a "platform for CX" in a press release dated 21 November 2024, stating that XCaaS was its first platform to combine cloud unified communications and contact center capabilities 4053.
Platform branding and components
WarmTransfer's reading of the sources is that by 2026, 8x8's primary name for its combined UC, contact center, and CPaaS offering is "8x8 Platform for CX", while "XCaaS" persists as the older brand and in developer-portal page titles 54. The November 2024 release states that the platform integrates contact center, unified communications, CPaaS APIs, AI, Microsoft Teams, and 8x8 Technology Partner Ecosystem solutions 38.
The platform encompasses several core offerings:
- 8x8 Work is 8x8's UCaaS product, covering voice, video, chat, and messaging 47. It provides clients for Windows and Mac desktops, iOS, Android, and a browser version that requires no download 46.
- 8x8 Contact Center is 8x8's cloud CCaaS product, covering voice, chat, email, and digital channels 18. It documents integrations with Salesforce, Zendesk, Microsoft Dynamics, NetSuite, HubSpot, Zoho, and ServiceNow 8.
- 8x8 Engage extends digital engagement tools to employees outside the contact center who deal with customers, such as sales, field service, and finance 25.
- 8x8 Communication APIs let businesses embed communications in their own digital experiences 17.
- 8x8 AI Studio is described as a no-code, natural-language interface that contact center teams use to build, test, and deploy voice and digital AI agents 6.
- 8x8 Frontdesk operates as a desktop receptionist application for 8x8 Work users, requiring an X4 or higher license, the Frontdesk capability enabled in the Admin Console, and 8x8 Work for Desktop 7.11 or later 27.
- Microsoft Teams integrations are offered natively to give Teams users global telephony 44.
8x8 delivers its solutions through X Series packages, described in its 10-K as a tiered set of service plans 48. For organizations transitioning from older offerings, the Classic to X Series upgrade takes about 15 minutes, during which the Account Manager admin portal is unavailable, though services keep working and active calls stay connected 14. The upgrade FAQ states that call-flow setup and the 8x8 Work desktop and mobile apps do not change 15.
Operations and licensing
8x8's fiscal year ends on 31 March; its FY2026 Form 10-K covers the year ended 31 March 2026 and sits in an EDGAR directory timestamped 22 May 2026 26. As of 31 March 2026, 8x8 had 1,819 full-time employees, with 70% of them outside the United States 24. Carrier partnerships extend service availability to over 100 countries and territories 42. 8x8 states that it staffs network operations centers in the United States, United Kingdom, Romania, Indonesia, Singapore, and the Philippines 34.
Licenses form part of the subscription and do not expire unless cancelled, allowing an organization to have as many users as it has licenses 32. Admins view licenses in the 8x8 Admin Console under Home > Licenses, where they can filter by country, license ID, and status (assigned, unassigned, or suspended) 31. The Admin Console groups licenses into 4 categories: 8x8 Work licenses, VCC (contact center) licenses, 8x8 Operator Connect licenses, and 8x8 XF Workspace and 8x8 Engage licenses 30. Operator Connect licenses are sold in Metered and Nationwide variants 37.
Calling destinations and usage limits correspond to license tiers:
- An X1 license includes unlimited calling to 1 country (domestic only), subject to fair use 49.
- An X2 license includes unlimited calling to 14 countries, and X3 includes calling to 32 countries, subject to fair use 51.
- The X4, X5, X6, X7, and X8 licenses include calling to 48 countries 52.
- Business users on X1 to X5 licenses receive unlimited calls to standard-tariff landline and mobile numbers in their covered countries under 8x8's fair-use policy 50.
- Contact center users on X6, X7, or X8 licenses receive a pooled fair-use allowance of 4,000 inbound and outbound call minutes per user per month 10.
Network requirements
8x8 plans for symmetric voice bandwidth of 90 kbps per call with G.711, 90 kbps with G.722 (UC calls only), and 35 kbps with G.729 16. 8x8 Contact Center adds about 30 kbps symmetric per call on top of voice codec bandwidth 9. Planning guidance recommends leaving 50% of available bandwidth free to absorb usage spikes 29.
Network performance targets require 0% packet loss, under 20 ms jitter, and under 100 ms latency to 8x8 data centers, though VoIP often still functions at 150-200 ms 33. 8x8 marks real-time voice media DSCP 46 (EF) and SIP signalling DSCP 26 (AF31) 23.
Port and security requirements include:
- SIP signalling uses UDP ports 5199, 5299, 5399, and 5060 43.
- Secure SIP uses TCP ports 5443 and 5401 43.
- RTP media uses UDP port ranges 24000-30999, 38000-44999, and 50000-65535 41.
- 8x8 Meet uses UDP port 10000 41.
- TCP port 443 must remain open 41.
- Security standards mandate TLS 1.2 or better 45. Chrome and Edge are recommended, while Firefox and Safari are listed as validated browsers 45.
Developer portal and APIs
The 8x8 Developer Portal groups APIs into XCaaS Actions & Events, XCaaS Analytics & Content, XCaaS Administration, CPaaS Connect & Communication APIs, Jitsi as a Service (JaaS), and Technical Partners 22. Authentication models vary across these interfaces: Contact Center realtime and historical analytics, Cloud Storage Service, Quality Management & Speech Analytics, and Contact Center Chat use OAuth, whereas Work Analytics, Customer 360, and CHAPI Work Chat require an API key 36. Where OAuth is used, tokens are requested from https://api.8x8.com/oauth/v2/token using the client_credentials grant, and access tokens expire after 1,799 seconds 35.
The 8x8 Administration API operates against the base URL https://api.8x8.com/admin-provisioning and requires an API key in the x-api-key header on every request 2. As of its 16 January 2026 update, the Administration API is version 1.0 in limited-access beta, and API keys cannot yet be generated in the Admin Console 3. It manages users, ring groups, phone numbers, sites, and contacts, employing scroll-based pagination with a default page size of 100 and a maximum limit of 1,000 5. Rate limits allow 100 requests per minute per API key, bursts up to 20 requests in 10 seconds, and 10 concurrent asynchronous operations per organization 4.
Contact Center realtime metrics use version v5 (named as current as of October 2022) and require multitenant customers to pass an X-Tenant-Info header containing their tenant ID 1213. The realtime statistics API routes requests across distinct regional base URLs for the US (api.8x8.com/analytics/cc), Europe (/eu/), Asia-Pacific (/au/), and Canada (/ca/) 11.
8x8 CPaaS (Connect) operates across 4 regional deployments: Asia Pacific (the default, using {product}.8x8.com), Europe ({product}.8x8.uk), North America ({product}.us.8x8.com), and Indonesia ({product}.8x8.id) 20. 8x8 states that targeting the regional CPaaS URL corresponding to an account's region maintains API call data and logs within that region 19. WarmTransfer's reading of the sources is that contact center analytics APIs and CPaaS APIs use different regional URL schemes and region sets, so a CPaaS region choice does not imply the contact center region 7.
