Bell Megalink PRI Is Being Destandardized: What Businesses Need to Know

If your business still uses Bell Megalink PRI, now is the right time to start planning for what comes next.

In July 2026, the Canadian Radio-television and Telecommunications Commission (CRTC) approved Bell Canada’s request to destandardize Megalink Service, Bell’s legacy ISDN PRI offering.

This does not mean that every existing Bell PRI service will be disconnected immediately. Existing Megalink customers can continue using the service. However, Megalink is no longer available to new customers, and maintaining the aging technology is becoming increasingly difficult.

For Canadian businesses that still rely on PRI, this is an important opportunity to review their options and plan a transition before the existing infrastructure becomes more difficult or costly to support.

What Is Happening to Bell Megalink PRI?

Bell Canada requested approval to destandardize its Megalink Service because the technology has become increasingly difficult to maintain.

According to the CRTC, the network equipment supporting Bell Megalink is more than 30 years old and is no longer supported. Bell also reported that the manufacturer has discontinued the equipment, making replacement parts increasingly difficult and expensive to obtain.

The CRTC approved Bell’s application through Telecom Order CRTC 2026-194 on July 31, 2026.

What Does Destandardization Mean?

Destandardization does not mean that the service disappears immediately.

For existing Bell Megalink customers:

• Existing service can continue.
• Existing customers can still submit requests for moves, additions, and changes.
• Megalink is no longer available to new customers.
• Certain longer-term contract provisions have been changed.
• Businesses should begin evaluating suitable alternatives as part of their long-term telecommunications planning.

In other words, businesses still using Bell PRI have time to plan, but they should not assume that PRI will remain a long-term technology option.

Why Businesses Should Start Planning Now

Many businesses continue to rely on PRI because their existing phone systems still work.

A company may have an established PBX, dedicated telephone numbers, paging systems, door phones, fax services, or other equipment connected to its PRI infrastructure.

Replacing the entire phone system simply because the carrier is moving away from PRI may not be necessary.

Instead, businesses can evaluate whether the PRI connection can be replaced while keeping the existing PBX.

This can make the transition more manageable and reduce the need for a large, immediate technology replacement.

You May Not Need to Replace Your Existing PBX

One of the most important considerations for businesses is that moving away from Bell Megalink does not necessarily mean replacing the entire phone system.

iTeraTEL can replace the carrier PRI service with SIP Trunking and, where required, provide a gateway that presents a PRI interface to the existing PBX.

From the PBX’s perspective, the connection can continue to operate through the PRI interface it was designed to use.

The underlying telephone service, however, is delivered through iTeraTEL’s SIP network.

This approach can allow a business to modernize its carrier connection without immediately replacing its existing phone system.

Bell PRI to SIP Trunking: A Practical Migration Path

For many businesses, moving from PRI to SIP Trunking can provide a gradual path toward a modern IP-based communications environment.

Instead of replacing the carrier connection and phone system at the same time, a business can:

1. Keep its existing PBX.
2. Replace the Bell PRI connection with SIP Trunking.
3. Use a PRI gateway where required.
4. Continue operating the existing phone system.
5. Plan the eventual PBX replacement separately.

This staged approach can help businesses manage costs, minimize disruption, and avoid replacing functioning equipment before it is necessary.

What Can You Move to After Bell Megalink?

The right replacement depends on the business’s existing phone system, number of channels, calling requirements, network environment, and long-term communications strategy.

Potential options include:

SIP Trunking

SIP Trunking can connect an existing PBX to a modern IP-based telephone network.

For businesses that want to keep their current PBX while replacing Bell PRI, this can provide a practical transition path.

Hosted PBX

Businesses that are ready to move away from traditional on-premises phone systems can consider a Hosted PBX solution.

Hosted phone systems can provide modern calling features while reducing reliance on aging PRI infrastructure.

Microsoft Teams Calling

Organizations already using Microsoft Teams may also evaluate Microsoft Teams Calling as part of a broader communications strategy.

IP PBX

Businesses that want greater control over their telecommunications environment can consider moving to an IP-based PBX.

The appropriate option depends on the organization’s existing infrastructure and business requirements.

What Should Bell PRI Customers Do Next?

If your business still uses Bell Megalink PRI, you do not necessarily need to replace your entire phone system today.

However, this is a good time to understand your current infrastructure and identify a practical migration strategy.

Start by reviewing:

• Your existing PBX and PRI equipment
• Number of PRI channels
• Telephone numbers and DIDs
• Calling requirements
• Paging, fax, door phone, and other connected equipment
• Current contract terms
• Internet connectivity
• Future phone system requirements

Understanding these factors can help determine whether SIP Trunking with a PRI interface, Hosted PBX, Microsoft Teams Calling, or another solution is appropriate.
