UCaaS Buyers Guide: Features That Actually Matter for Enterprise Communications

Different users need different things, and a single feature checklist hides that. Group your users before you evaluate anything.

• Office staff who make and take calls, join meetings and use messaging.
• Reception and front-desk users who need to see and transfer calls quickly.
• Remote and hybrid staff who rely on a softphone or mobile app.
• Frontline and shared-device users with basic calling needs.
• Customer service or sales teams that handle high call volumes and need queues, reporting and CRM links.

Also note your sites, the number of users in each, and the equipment you want to keep, such as analog devices, door phones and fax lines.

Voice remains the core of most deployments.

• Call quality. Ask which codecs are supported. Wideband codecs deliver clearer speech than narrowband ones, and the platform should negotiate the best one available. Quality in practice depends on your network, so test with a pilot group.
• Call routing. Look for an auto attendant, ring groups, call queues, time-of-day rules, holiday schedules and call forwarding that can be changed without a support ticket.
• Voicemail. Voicemail to email and transcription save time, and shared mailboxes help teams.
• Mobility. A desk phone, softphone and mobile app should all work with one number and one set of call settings, and calls should move between them.
• Reception tools. Presence, busy lamp fields and fast transfers for staff who handle many calls.
• Emergency calling. Confirm how emergency calls work for every user type, how locations are registered for staff who move or work remotely, and who is responsible for keeping addresses current.

• Video meetings. Check participant limits, screen sharing, recording, transcripts, breakout rooms and a way to run larger sessions. Test on typical laptops and in your meeting rooms.
• Team messaging. Channels, direct messages, file sharing, search and the ability to include external guests.
• Presence. Status that follows calendar and call activity.
• Meeting room support. Room systems that work with the platform, so rooms and remote participants share the same experience.

Many organizations already use a separate meeting or messaging tool. Decide whether you want to consolidate or run alongside, and check how the tools interoperate. The guide to remote work communications covers how to set norms across tools.

A platform that fits into your daily tools saves more time than a handful of extra features. Check these:

• Your customer relationship system, so calls are logged and records open when a customer rings.
• Your email and calendar platform, for presence and meeting scheduling.
• Your identity provider, for single sign-on and automatic creation and removal of users.
• Your help desk or line-of-business tools, if call data matters there.
• An open programming interface, in case you need a custom integration.

Ask to see each integration working. A listing on a marketplace page does not tell you how deep it goes.

• A clear admin portal where a non-specialist can add users, change routing and assign numbers.
• Role-based admin rights, so a receptionist can change a greeting without access to billing.
• Call detail records and reports on call volume, missed calls and queue times.
• Call quality reporting that identifies which users and sites have problems.
• Bulk tools for adding many users, which matter during rollout.

• Encryption of signalling and media in transit, with TLS for signalling and SRTP for voice media.
• Multi-factor authentication and single sign-on for users and administrators.
• Audit logs for administrative changes.
• Controls on call recording, including where recordings are stored, how long they are kept and who can listen.
• Data location. Ask where call data, recordings, voicemail and messages are stored, and whether a Canadian region is available.
• Notice to callers when calls are recorded, and retention that matches your privacy obligations and sector rules.
• The provider’s independent assurance, such as SOC 2 reports or ISO/IEC 27001 certificates, and the scope each one covers.

Two layers matter. The first is the provider’s service, including its data centres, redundancy and the service level it commits to. The second is your own connectivity, which the provider does not control. Ask how the service is spread across locations, how failover works, and what the credit is when it falls short. The SLA guide explains how to read the numbers. Plan what happens when a site loses its internet connection. Options include automatic forwarding to mobile numbers, a backup circuit or a cellular failover.

Most UCaaS problems trace to the network, not the platform. Before rollout, check that the sites have:

• Enough bandwidth for the number of simultaneous calls and meetings. The bandwidth requirements guide explains how to size it.
• Low delay, low jitter and low packet loss, which matter more for voice than raw speed.
• Traffic prioritization for voice and video on the local network and at the edge of the site.
• A resilient internet connection. A dedicated circuit with service commitments, described in the dedicated internet access guide, suits sites where voice is critical.
• Good Wi-Fi coverage if staff use softphones on mobile devices.
• Power over Ethernet switches if you will use desk phones.

• Porting. Moving existing numbers to the new platform takes planning. Ask who coordinates the port, what information is needed, and how the cutover avoids a gap in service.
• Number types. Check availability of local numbers in the area codes you need, toll-free numbers, and the ability to keep a number when staff move offices.
• Analog devices. Fax machines, door phones, alarm lines and elevator phones often need adapters or a different arrangement. List them early, since they cause late surprises.

Also check term length, rights to add and remove users, price changes at renewal, early termination terms, and what happens to your numbers and data if you leave.

• Selecting on a feature count instead of on the needs of each user group.
• Skipping a pilot, so call quality problems appear only after full rollout.
• Underestimating network work at sites.
• Forgetting analog devices and emergency calling arrangements.
• Leaving number porting to the end of the project.
• Paying for premium tiers that most users will never use.
• Accepting an uptime promise without understanding what is excluded.

• Where are our data, recordings and voicemail stored, and is a Canadian location available?
• How is emergency calling handled for remote and mobile users?
• Who manages number porting, and what is the process for a site with many numbers?
• Which integrations are included, and can you show them working with our tools?
• What service level applies to the platform, and what is excluded?
• What happens to our service if our internet connection fails at a site?
• What are the full recurring costs, including add-ons and usage charges?
• What are the exit terms, and how do we keep our numbers?

What is the difference between UCaaS and VoIP?

VoIP is the technology that carries voice over an IP network. UCaaS is a service that combines voice with meetings, messaging, presence and other tools, delivered from the cloud.

What is the difference between UCaaS and a contact centre platform?

UCaaS serves general business communication. A contact centre platform adds features for handling high customer volumes, such as advanced queuing, agent supervision and detailed performance reporting. Some UCaaS products include basic versions of these.

How long does deployment take?

It depends on the size of the organization, the state of the network and the number of numbers to port. Number porting and network upgrades are usually the longest parts, so start them early.

Can we keep our existing phone numbers?

Usually yes, through number porting. Confirm eligibility early, gather the account information the porting process requires, and agree a cutover plan that avoids a gap in service.
