By Bill Perna,

Phone service has changed over time. Many members are familiar with traditional landline phones, while newer services use the internet to place calls. Here’s a simple explanation of how they compare.
Traditional Telephone Service (POTS)
POTS stands for Plain Old Telephone Service. This is the traditional landline phone system that has been used for decades.
How it works:
- Uses dedicated copper phone lines
- Carries voice as analog signals
- Each call uses its own physical circuit
Key benefits:
- Very reliable
- Works during power outages (powered from the phone company)
- Simple and familiar
Limitations:
- Fewer features
- Aging infrastructure
- Higher monthly cost
Voice over Internet Protocol (VoIP)
VoIP is a modern phone service that uses your internet connection to make and receive calls.
How it works:
- Converts your voice into digital data
- Sends calls over the internet or a private network
- Uses equipment like a modem, router, or IP phone
Key benefits:
- High-quality sound (often HD voice)
- Advanced features (voicemail to email, call forwarding, mobile apps)
- Easy to add or change lines
- Often lower monthly cost
Things to know:
- Requires electricity and an internet connection
- May need battery backup to work during power outages
Side-by-Side Comparison
| Feature | Traditional Phone (POTS) | Internet Phone (VoIP) |
| Connection | Copper phone line | Internet connection |
| Power during outages | Yes | No (without backup) |
| Sound quality | Standard | High definition |
| Features | Basic calling | Advanced calling tools |
| Flexibility | Limited | Very flexible |
| Technology | Legacy | Modern |
Which Is Right for You?
POTS may be a good choice if you:
- Need phone service during power outages
- Use older equipment (alarms, medical devices, elevators)
- Prefer a simple, basic phone
- Don't mind the high price
VoIP may be a good choice if you:
- Have reliable internet service
- Want modern calling features
- Work from home or have multiple devices
- Want a flexible, future-ready solution
Important Note on Reliability
VoIP can be just as reliable as traditional phone service when paired with battery backup or generator power. Many members choose VoIP for its features and flexibility while adding backup power for peace of mind.
