General FAQs

Does a DuraFon 1x support call waiting, and/or 3 way calling?

Yes, provided this is handled by the phone company or phone system it is connected to. You will need to press the flash key to flip between callers.

Does my DuraFon 1X have built in Voice Mail?

No the DuraFon 1X system does not have voice mail or an answer machine.

Does the DuraFon 1X handset have speakerphone on calls?

Yes and No. All phones built after Nov. 2007 with serial number 07A101340 or higher will now include this feature

Will my DuraFon 1X base units interfere with each other or other communication devices?

Yes, Base units and or the high gain antennas should be at least 30' apart from each other, and other electronic equipment for best performance and to reduce interference.

What security does the DuraFon system use?

The DuraFon Systems 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.

Can I answer a second call coming through a secondary base while on a call with an initial base?

No. The DuraFon 1X handset can only utilize one connection at a time. Outside of the Telephone service provider's "Call Waiting" the only way to answer a second inbound call is to be free to connect. If you need this capability, we suggest using our multiline systems (DuraFon PRO).

Can a 1x handset work with a 920, 4x, or PRO base unit?

No. 1x is not compatible with any other system.

Does a DuraFon 1x support call waiting, and/or 3 way calling?

Yes, provided this is handled by the phone company or phone system it is connected to. You will need to press the flash key to flip between callers.

How different is the range using 2 way, or broadcast handset to handset, as compared to base to handset communication?

Two way and broadcast handset to handset are independent of the base unit. Range will be less than a typical incoming call or broadcast from the base unit, typically 25% to 50% less. If the external antenna is used on the base unit, the range difference will be even more noticeable. To maximize 2 way or handset broadcasts, use the long antenna on the handsets

When sharing a line with another non-Engenius phone, I can’t join in, they can’t hear me?

We added this feature to avoid howling or feedback in speakerphone mode when starting a new call. Simply press any digit to turn on the voice path. This feature is now on all Durafon 1x with speakerphone.

Why would EnGenius use 900Mhz, when this is an older technology compared to the newer 2.4 and 5.8Ghz cordless frequencies?

Contrary to common belief, range is actually better at lower frequencies. Lower frequencies are less absorbed by objects and less affected by walls, buildings, trees, and even open air. Additionally, we use 900MHZ to avoid the sharing of WiFi networks, which would not only cause interference, but also reduce range for our system as well. Thirdly, the FCC allows more power to be used at lower frequencies because lower frequencies are safer for human exposure.
