Business VoIP

Voice over your internet connection, planned properly.

Move analog lines, a PRI or another VoIP provider onto SIP service sized for how many calls you actually run at once — with your numbers coming with you.

  • SIP trunks for an existing PBX
  • Bandwidth and quality review
  • Port your current numbers

3CTel Business VoIP carries business calls over your internet connection instead of copper lines or a PRI circuit. Calls are handled by a hosted phone system with routing, voicemail to email, desktop and mobile apps, and Canadian local and toll-free numbers. It can also feed SIP trunks to a PBX you already own. Your network is reviewed before cutover, and 911 is configured with your registered service address.

What changes for your business.

Calls stop breaking up mid-sentence

We size concurrent calls against your actual upload speed and set voice priority on the network, instead of hoping the connection holds.

Your existing PBX keeps earning its keep

If you already run a 3CX system or another IP PBX, SIP trunks connect it to the outside world without replacing the hardware and training you paid for.

Nobody has to learn a new number

Existing numbers port across. The current line keeps working until the port completes, so there is no window where customers hear nothing.

One voice service across every site

Branches, a warehouse and a home office share the same trunk group, extension range and dial plan rather than separate accounts per address.

Core capabilities.

SIP trunking for an existing PBX

Registration or IP-authenticated trunks with the channel count, codecs and caller ID your PBX expects — including a 3CX system you already own.

Bandwidth and readiness review

We check upload capacity, jitter and the router before cutover, and flag anything that will degrade voice under load.

QoS and network guidance

Voice traffic tagged and prioritised on your LAN, with VLAN and firewall recommendations your IT provider can apply.

Number porting and DID ranges

Port single lines, hunt groups or a full DID block, and add new local or toll-free numbers alongside them.

Failover routing

If a site loses internet, inbound calls follow a preset path — mobiles, another location or voicemail — instead of failing at the door.

Cloud PBX when you want out of hardware

Prefer to retire the box entirely? The same numbers land on a hosted cloud PBX in Canada with menus, queues and apps included.

Call detail records

Every call logged with number, direction, duration and disposition, exportable for costing and dispute checks.

SIP devices and ATAs

Desk phones, cordless handsets, conference units and analog adapters for the fax machine, alarm panel or door phone still on a copper pair.

Common use cases.

Business leaving analog lines or a PRI

A multi-line key system on copper moves to SIP with the same published number and a lower fixed line cost structure.

Company that already owns a 3CX system

Keep the PBX and its licences; swap the trunks. Configuration is supplied and tested with your administrator before cutover.

Switching from another VoIP provider

Numbers port over, devices are reprovisioned, and the old account stays live until the new service is proven.

Multi-site operation with uneven internet

Sites with weaker connections get lower codec settings and failover rules so a busy afternoon does not take voice down.

AI conversation intelligence on every VoIP call

Because calls run on the cloud platform, conversation intelligence can summarize each one, produce a transcript and flag keywords or sentiment for review, and an AI workflow then logs the summary against the contact in your CRM.

Setup and migration.

A VoIP migration is mostly preparation. The order below keeps your current line in service while the new one is built and tested.

  1. Assess the connection and current setup

    We document line counts, peak concurrent calls, the existing PBX or key system, and what your internet can carry today.

  2. Provision trunks or extensions

    Trunks are built with the right channel count and credentials, or cloud extensions are created if you are moving off hardware entirely.

  3. Configure and test in parallel

    Your PBX or devices are configured against a temporary number so calls, transfers and caller ID are verified before anything changes.

  4. Port and cut over

    Numbers transfer on the date the carriers confirm. Your old service stays up until then, and we monitor the first days of live traffic.

AI in this product

AI on your VoIP service

The AI layer sits on the same cloud platform as your VoIP lines, so it works on every call without extra hardware.

Quality hot spots by site and time

Jitter, packet loss and latency are tracked per call and correlated with office, device and hour, so a recurring problem is traced to its network path rather than guessed at.

Spam and robocall pattern flags

Inbound patterns that look like robocalls or spam across your numbers are flagged with proposed screening or blocking rules, and nothing is applied until you approve each rule.

Transcripts and summaries on any line

Where recording is enabled and announced to callers, calls on any VoIP line are transcribed and summarized in English or French, giving staff searchable notes instead of audio files.

Common questions, answered directly.

What is the difference between VoIP and a traditional phone line?

A traditional line delivers one call over a dedicated copper pair or a channel on a PRI circuit. VoIP converts the call to data and sends it over your internet connection, so capacity is a matter of bandwidth rather than physical lines. Features such as routing, voicemail to email and apps live in the hosted system, and users can work from any location with a connection.

Does VoIP need a special internet connection?

No, but it needs a stable one. Voice uses a small amount of bandwidth per call; what matters more is consistent upload speed and low jitter. During planning the connection and router are reviewed, voice traffic is prioritised on the local network where possible, and a failover path for inbound calls is set in case the connection drops.

How does 911 work on a VoIP phone?

Canadian VoIP providers must provide 9-1-1 service and warn customers of its limitations. Because a VoIP call can come from any location, a registered service address is confirmed with you for each site and each user’s device at setup. You are responsible for updating that address when staff or devices move so responders receive the right location.
