FAQs

1. What is SIP Trunking?

SIP trunking, or Session Initiation Protocol trunking, allows businesses to replace traditional phone lines with an internet connection for both toll free and local numbers.

Here's The Bottom Line:

SIP trunking, or Session Initiation Protocol trunking, allows businesses to replace traditional phone lines with an internet connection for both toll free and local numbers.

2. What Are the Benefits of SIP Trunking?

Switching to SIP trunking offers three key benefits that make it an easy choice for businesses.

Here’s why:
  • Save Money with Cheap SIP Trunking Services: SIP trunking can reduce your phone costs by 60-80% compared to ISDN phone lines. Why? Because calls—local, mobile, long-distance, and even international—are routed over the internet, making them much cheaper.
  • Easily Scale Your Business: SIP trunking services are hosted virtually, so there’s no bulky hardware or maintenance required. Need a new number or to handle more calls? Add or update numbers instantly, regardless of location, without extra equipment.
  • Improve Phone Service Reliability: SIP trunking relies on cloud technology, offering built-in redundancy. In case of an outage, your service can automatically reroute to backup data lines or mobile devices, ensuring your business stays connected.

3. Which SIP Pricing Plan is Cheaper: Unlimited Minutes or Carrier-Grade?

Carrier-grade SIP pricing (what Unitel Voice SIP offers) is almost always more affordable than unlimited SIP trunking plans.

Here’s why:
  • Unlimited Plans Are Not Truly Unlimited: Many “unlimited” SIP plans include hidden Fair Use Policies, which limit the minutes you can actually use. Exceeding these limits can disrupt your service, putting your business at risk.
  • Unlimited Plans Restrict Concurrent Calls: Unlimited plans cap the number of channels (or simultaneous calls) you can handle. To accommodate peak demand, you might have to pay for channels you rarely use.
  • Why Carrier-Grade Pricing Wins: With carrier-grade SIP trunking, you only pay for the minutes you use—no hidden limits, no wasted spending, and no unnecessary risk. You get unlimited channels and true flexibility, making it a cost-effective option for small businesses and large call centers alike.
