The EnGenius Durafon1x system allows you to add additional bases. Therefore, more than one line.
To add additional base unit:
Register all handsets to the primary base originally used in the system. (Click here)
Get an administrator handset (ID 11, or 12) and the additional base unit you plan to add.
Power-up the base.
Press and hold down the register (labelled REG) button on the base until all four green LED lights illuminate.
Press menu on the handset followed by 6 (Registration) 3 (set base), and then choose 20 (for base #2).
(Note additional bases 3, and 4 can be done the exact same way, however their base numbers would be 30, and 40 accordingly.)
The second base in the example (base 20) can accept 9 more handsets (ID 21-29) etc.
Total of 36 handsets can be used with 4 base stations with the 1x system.
Base 10 = ID11-19 (9 handsets)
Base 20 = ID21-29 (9 handsets)
Base 30 = ID31-39 (9 handsets)
Base 40 = ID41-49 (9 handsets)
NOTE: Bases should be separated from each other, and from external antenna(s) by at least 10 metres (33 feet).
Each base should be connected to a different external line. DO NOT connect 2 Bases to the same line.
The DuraFon 1X does not have Call Waiting feature for a second line provided by a second Base. If you are talking on Base 1/Line 1, and a call comes in on Base 2/Line 2, you will not be alerted to the second call, and you can’t put the first call on hold to answer the second incoming call. The caller on Line 2 will simply not get answered, but could leave a message (if supported by the phone service provider).
