Bring Your Own Carrier (BYOC) & Upgrade Calls

Bring Your Own Carrier (BYOC) lets you use your existing telecom carrier with CloudTalk instead of CloudTalk’s bundled calling providers. Your carrier continues to handle call delivery, while CloudTalk runs the call center layer (routing, agents, analytics, AI, integrations, and much more).

With CloudTalk BYOC:

• Your SIP carrier connects through a guided setup
• Calls are routed automatically in the background
• Your team works in CloudTalk as usual

In short, the bring your own phone carrier setup is designed for teams that want flexibility without rebuilding their entire telecom setup.

BYOC is a good fit if you already work with a carrier you want or need to keep. This often applies to growing SMBs, mid-market, and enterprise teams with existing contracts, regional requirements, or complex setups.

BYOC may be right for your business if you:

• Have negotiated carrier rates you want to keep
• Operate in regulated or country-specific markets
• Want to avoid large-scale number porting
• Need CloudTalk’s call center features on top of your carrier

If you don’t have a carrier yet, BYOC isn’t your best choice. Instead, you should choose CloudTalk’s bundled calling network. The platform works with trusted carrier partners and supports calling in 160+ countries, so teams can get coverage and call quality without managing telco carriers.

Businesses use BYOC to gain flexibility through a bring-your-own-carrier cloud model, without disrupting their telecom foundation. It allows teams to modernize their call center while keeping existing carrier relationships intact.

Common business reasons for BYOC include:

• Keeping long-term contracts and pricing
• Meeting regulatory or local carrier requirements
• Avoiding the risk and downtime of number porting
• Preserving reliable call quality
• Supporting multi-country or hybrid setups

SIP trunking is the technical method of connecting voice traffic over the Internet. BYOC is the business model that lets you bring your own SIP-based carrier into a virtual call center platform like CloudTalk.

In simple terms:

• SIP trunking is the technology
• BYOC is how you use that technology with a call center provider

Hosted PBX replaces your entire phone system and carrier with a single provider. BYOC keeps your carrier but upgrades how calls are managed.

Choose BYOC if:

• You already have a carrier you want to keep
• You need virtual call center features on top

Choose a hosted PBX-style setup if:

• You’re starting from scratch
• You want everything bundled into one provider, including virtual numbers

CloudTalk supports both approaches, depending on your needs.

In 2026, more and more teams are operating across regions, regulations, and time zones. BYOC gives them the flexibility to adapt without rebuilding their telecom stack.

Businesses are switching to BYOC because:

• Compliance requirements are increasing
• Carrier contracts are more complex
• Their call centers need better, more modern tools, not new carriers
• Hybrid and gradual migrations are more common

With BYOC, call rates stay with your carrier. CloudTalk pricing covers the call center platform, features, and call handling.

In practice, CloudTalk BYOC pricing works like this:

• Your carrier bills call usage (minutes, destinations, rates)
• CloudTalk bills your call center subscription and any selected add-ons (like AI agents or Conversation Intelligence, shall you opt for them)

This keeps billing clear as your telecom costs stay with your carrier, while CloudTalk covers the software layer your team works in.

Note: outbound calls routed via BYOC may also include a CloudTalk usage fee, which is confirmed before go-live (or contact CloudTalk beforehand for more info).

Yes. That’s one of the main reasons teams choose BYOC. You keep your existing carrier contracts, call rates, and phone numbers without forced porting. A BYOC solution like CloudTalk connects to your carrier so you can upgrade your call center without changing what already works.

Yes. BYOC does not limit CloudTalk functionality. You get the same call routing, analytics, AI features, CRM integrations, and workflows as with CloudTalk’s bundled calling network.

In other words, your carrier handles call delivery. CloudTalk handles everything around it.

Most BYOC setups take days, not months. The exact timeline depends on your carrier and setup complexity.

Here’s how setup usually works:

• Share carrier details with CloudTalk
• Compatibility is validated
• The connection is configured and tested
• You go live once everything is confirmed

CloudTalk guides the process to ensure a smooth launch.

CloudTalk BYOC works with most SIP-based carriers. If your carrier supports SIP trunking, there’s a good chance it can be connected.

To keep things smooth, we confirm compatibility during onboarding and help you set it up the right way before you go live.

If your carrier has an outage, calls routed through that carrier can be impacted. CloudTalk still runs as your call center platform, so your call flows, users, and setup stay in place.

If you’re using this hybrid BYOC setup, you can also reduce risk by:

• Routing some calls through CloudTalk’s global calling network
• Adjusting call flows to keep teams reachable
