The cost is $49.95 USD per month per phone line and includes 1000 free minutes (16.6 hours) each month, and then $0.04 cents per minute to any in-country phone number.

The Durafon solution may have 1, 2, 3 or 4 phone lines. A phone number may be dedicated to 1 handset (up to 4 handsets having their own number)…. OR, phones may be “party” configured to share 1 to 4 phone lines, where these numbers will ring all phones at once. A calling handset phone will pick up the first available unused phone line. You may have both “dedicated line” and “party” configurations on a single base station. Here is more information on VoIP Phone Service Over Satellite offered by Ground Control.

Connect Up To 2 Miles From Base

These phones are the highest powered cordless phones available in North America, extending range up to 2 miles from the base station. The connection penetrates 12 walls or 12 floors (stories), so the base station can be outside while you work inside. Each phone includes an additional 9″ whip antenna that helps extend existing range. Antennas are easily swapped with a quick-twist. The optional $250 high-gain base-station antenna extends the range up to 5 miles.

Highly Secure

The DuraFon Pro handset phones utilize Digital Spread Spectrum (DSS) with Frequency Hopping of 100 channels per second over 128 channels to maintain clarity and privacy. In addition, the base unit provides individual handset with one of over 65,000 random security codes to ensure that another system’s handset is unable to link to another (non-related) base unit.

Long-Range Distances

The Durafons are the longest range cordless phones available for North America. While range may be slightly affected by environmental conditions, below are some advertised guidelines:

  • 12 floors of building penetration
  • 250,000 sq. ft. in a warehouse or retail store
  • 3,000 acres on a farm or ranch.

TurnKey – Commissioned – Configured – Tested and Working
