In the world of telecommunications, businesses and individuals are constantly seeking ways to reduce costs while maintaining reliable communication services. One such solution is Carrier Pre Select (CPS), a service that allows users to automatically route calls through a preferred provider without changing their existing phone line.
Carrier Pre Select CPS is particularly beneficial for organizations that make a high volume of calls, as it can significantly reduce expenses without requiring additional infrastructure. This article explores what CPS is, how it works, its advantages, potential drawbacks, and why it remains a crucial option in modern telecom strategies.
What Is Carrier Pre Select (CPS)?
Carrier Pre Select (CPS) is a telecommunication feature that enables customers to select an alternative service provider for outgoing calls while retaining their original landline connection. Unlike traditional methods that require dialing a prefix (such as 1280 or 123), CPS automatically directs calls through the chosen carrier at pre-negotiated rates.
Key Features of CPS:
- No need to change phone numbers – The existing line remains active.
- Automatic call routing – No manual prefix dialing required.
- Cost-effective – Often cheaper than standard provider rates.
- Flexibility – Users can switch carriers without altering their primary line.
This service is widely used in the UK, Europe, and other regions where telecom deregulation allows multiple providers to compete for call routing services.
How Does Carrier Pre Select Work?
CPS operates through a simple yet efficient mechanism:
- User Makes a Call: When a customer dials a number, the call is initially sent to the local exchange (the default telecom provider).
- Automatic Carrier Selection: Instead of routing the call through the default provider, the exchange recognizes the CPS agreement and redirects the call to the pre-selected carrier.
- Call Completion: The chosen carrier processes the call at its designated rates, and the recipient receives it normally.
Types of Calls Supported by CPS:
- Local calls
- National (long-distance) calls
- International calls
- Mobile calls (in some cases)
Since CPS works at the exchange level, users do not need any special equipment or software—just an agreement with a CPS provider.
Benefits of Using Carrier Pre Select
1. Significant Cost Savings
One of the biggest advantages of CPS is reduced call charges. Businesses that make frequent long-distance or international calls can save substantially by routing calls through a cheaper provider.
2. No Need to Change Phone Numbers
Unlike switching providers entirely, CPS allows users to keep their existing phone numbers while still benefiting from competitive call rates.
3. No Additional Hardware or Setup
Since CPS operates through the telecom exchange, there’s no need for new phones, adapters, or complex installations.
4. Flexibility to Switch Providers
If a better deal becomes available, users can easily switch CPS providers without disrupting their primary phone service.
5. Improved Call Management
Some CPS providers offer enhanced call analytics, fraud prevention, and customized routing options, which can be valuable for businesses.
CPS vs. Other Call Routing Methods
To understand why CPS is advantageous, it’s important to compare it with alternative call routing solutions:
| Feature | Carrier Pre Select (CPS) | Indirect Access (IA) | Full Provider Switch |
| Prefix Required? | No | Yes (e.g., 1280) | No |
| Keep an Existing Number? | Yes | Yes | Sometimes |
| Call Routing | Automatic | Manual prefix needed | Fully switched |
| Setup Complexity | Simple (exchange-level) | Simple | May require new line |
| Cost Efficiency | High | Moderate | Depends on new provider |
Why Choose CPS Over Alternatives?
- More convenient than Indirect Access (no need to dial prefixes).
- Less disruptive than a full provider switch (no number porting or line changes).
- Better long-term savings compared to standard rates.
Potential Drawbacks of CPS
While CPS offers many benefits, there are some limitations:
1. Dependency on the Existing Line
If the primary phone line fails, CPS will not work, as it relies on the default provider’s infrastructure.
2. Limited Availability in Some Areas
Not all telecom providers support CPS, and availability may vary by region.
3. Possible Setup Fees
Some CPS providers charge an activation fee or require a minimum contract term.
4. Not Always the Cheapest for All Call Types
While CPS is generally cost-effective, some providers may offer better rates for specific call types (e.g., VoIP for international calls).
Is Carrier Pre Select Still Relevant Today?
With the rise of VoIP (Voice over IP), mobile calling, and digital telephony, some may wonder if CPS is becoming obsolete. However, it remains relevant for several reasons:
1. Landline Reliability
Many businesses still rely on PSTN (Public Switched Telephone Network) lines for stability, making CPS a viable option.
2. Regulatory Support
In countries with telecom deregulation, CPS promotes competition, keeping call rates low.
3. Cost-Effective for Certain Users
Companies with high call volumes (e.g., call centers, customer service teams) can still benefit from CPS pricing models.
That said, as more businesses transition to cloud-based phone systems, the long-term demand for CPS may decline.
Conclusion
Carrier Pre Select (CPS) is a powerful telecommunication solution that helps businesses and individuals reduce call costs without changing their primary phone line. By automatically routing calls through a preferred provider, CPS offers convenience, flexibility, and significant savings.
While newer technologies like VoIP are gaining traction, CPS remains a valuable option for landline users, especially in regions with competitive telecom markets. Businesses looking to optimize communication expenses should consider whether CPS aligns with their needs.
Final Recommendations:
✔ Compare CPS providers to find the best rates.
✔ Check availability in your region before committing.
✔ Monitor call usage to ensure CPS is cost-effective for your needs.
✔ Consider future-proofing with VoIP if long-term flexibility is a priority.
By understanding how Carrier Pre Select works and its role in telecom strategies, organizations can make informed decisions to enhance their communication efficiency while keeping costs under control.
