The SIP Trunking Advantage

SIP Trunking vs. Traditional (Analog) Phone Lines

The SIP Trunking Advantage

“Analog” may be the traditional means of voice communication, but it is not the most practical use of technology in this day and age.

Traditional (or analog) style phone lines and systems consist of a series of copper wires running from a phone company to the service location. This is called the PTSN (Public Switched Telephone Network) which uses telephone poles, telephone wires and phone jacks to carry your voice.

By having a traditional analog phone system, you are physically limited to the amount of existing lines that run to your location. If you have 8 analog phone lines and all 8 are in use, then incoming phone calls from clients will be answered with a busy signal. Nobody wants to continually call your business like they’re trying to win a prize package from the local radio station.

Did you know that most businesses relying on a traditional analog phone system pay for up to 50% more lines than they need – just to be safe?

The Pros of Traditional Phone Lines

  • Has been the primary means of voice communication throughout the years.
  • Reputation of being reliable and of good quality.

The Cons of Traditional Phone Lines

  • High cost per trunk.
  • Can only handle one conversion at a time.
  • Most companies experience “oversubscription” to phone lines (unused trunks billed monthly).
  • If phone lines are unavailable (or busy) all in bound and out bound calls are lost.
  • Moving locations with multiple phone lines comes with heavy installation costs per-line.

The SIP Trunking Advantage

What is SIP Trunking?

SIP stands for Session Initiation Protocol and is a telephony product that uses the internet to create a replicated (or virtual) phone line.

Call-One® centralizes your telephone network to one location with a virtual phone system that runs over your IP, creating substantial savings for businesses on their phone bills.


SIP Trunking vs. Analog Phone

With SIP Trunking there are no physical phone lines coming in to the building, giving you the ability add and remove voice channels with ease; without the installation of traditional phone lines.

This makes your phone system fully scalable and can be adjusted based on the number of locations you have (or even by your call history and usage). For example, you have 8 lines and they are all in use, every missed phone call is a missed opportunity.

SIP Trunking simplifies this situation by giving you flexibility. If your call volume is higher than your set voice channels, your service can “burst” for the next 24 hours to include up to twice the amount of your committed channels.

The Pros of SIP Trunking

  • SIP Trunking is transmitted over the internet.
  • By-passes traditional analog charges and limitations.
  • Typically 50% less than traditional rates.
  • Additional voice channels are available daily and on demand through “bursting”.
  • Pay for voice channels when you need them instead of committing to an oversubscription.
  • Adding or changing services can generally* be done for free and on the same day as part of the monthly service charge.
  • No additional costs to relocate when moving office locations.
  • Integrate off-site extensions and national numbers reducing long distance costs between locations.
  • Can be combined with analog lines for redundancy with the addition of a gateway.
  • With advanced features, phone calls can be received anytime and automatically forwarded if and when your internet becomes unavailable so no calls are lost.

The Cons of SIP Trunking

  • With careful planning, there aren’t any significant drawbacks to SIP Trunking. You will need to manage your network traffic to optimize voice communications, and ensure your internet connection stable.

    Bundle your SIP Trunk with a Call-One internet plan for peace of mind.
