Unlike systems in which a dedicated base station and extension handsets are packaged and sold separately (such as Brother's CTS-400 cordless phone system), the IBM 4900 is geared to function more as a stand-alone cordless phone, and it does indeed work well as a single unit. The IBM 4900 also interfaces with phone systems that have up to 12 extensions. The emphasis on single-unit design has, however, resulted in reduced range and less line-of- sight coverage compared to systems with a dedicated base station and multiple extension handsets. Nevertheless, in our tests, we found the coverage adequate for most office environments.
The IBM 4900 features a 24-number speed dial memory, as well as a caller ID display. Such features as 12 one-touch intercom buttons and call privacy will please small-business employees. Our only complaint was with the absence of a fast-charging feature, as the ni-cad battery requires more than three hours to charge.
With its digital spread spectrum technology, caller ID, and support for larger phone systems, the IBM 4900 four- line cordless phone should satisfy the general telephone needs of your home or small but growing office. --John Frederick Moore

- Good overall performance as a stand-alone unit
- One-touch intercom buttons

You can combine the IBM four-line 900 MHz digital spread spectrum cordless phone with caller ID, IBM four-line telephone, and IBM four-line telephone with caller ID to form a four-line, 12-unit, non-KSU telephone system. This phone comes with a one-year warranty.

It is a little complicated to set up (impossible) if you lose the instruction book. Codes must be entered to number each extension, shut off the ringer, etc. These work best if you have more than one of them. If so, you can transfer calls from one extension to the other. Otherwise, if you use this phone to answer a call and put it on hold, then pick up the held call with another (non-IBM) phone, the IBM phone think's it still has a call on hold, even though you have hung up with the non-IBM phone. The IBM phone will continue to ring every 30 seconds to warm you that you have a call on hold until you pick up the "dead" line and hang up. Individual lines can have their ringers shut off. There is a station-to-station intercom, and an all-stations paging.There is also a "do not disturb" button to shut off all the ringers on that extension. The hook up is with 2 standard household phone jacks.

But when I walk around the house, the party I'm talking to always hears some sort of noise due to the phone or headset chord rubbing agains this or that. Maybe I had a bum headset or phone. But the clincher for me was this phone is not compatible with other mfgrs. I have some phones mfgrd by VTech & daily heard random ringings & beeps from the IBM phone. I called the mfgr (TT Systems or something like that is the mfgr, IBM is just the name on the phone), TT said this 4-line phone can not be mixed and matched with other mfgrs. Well, I don't want to toss out my existing V-Tech phones. So I'm getting (2) additional V-Tech phones for my home office. My situation is I have 2 lines for work & 2 lines for home; and want all 4 lines in my office. By the way if you want a chordless phone with headset I definitely recommend looking at V-Tech, we've had 2 of their phones and their the best chordless I've found. Other than...Read more 6 of 6 people found the following review helpful: Where are the phones designed for 4 line home offices?, By A Customer This review is from: IBM 4900 4-Line 900 MHz Digital Spread Spectrum Cordless Phone with Caller ID (Office Product) I've read all five reviews. I've been looking for a well designed, affordable and reliable 4 line phone for over a year! I think I'm going to pass on the IBM 900 MHz Cordless, not only because of the problems identified but also because I, like some other reviewers, already have one four line phone (purchased as a make do strategy until I could find a phone more to my liking). I'm struck by the lack of variety and the extremely small number of manufacturers that offer 4 line cordless phones. I also find it amazing that features I've come to take for granted on l and 2 line phones (lighted displays, blinking lines, etc., seem to be lacking on the few 4 line cordless I've reviewed. If anyone knows of other brands, please let us know. |
