What wireless VoIP phones are compatible with the 3Com NBX systems? Are there several? What other companies make wireless phones?
http://www.3com.com/partners/advantage_programs.html is a link to their voice partner program. You can find out who partners with them. Also, doing a search of 3Com NBX phones in a web browser brings up quite a listing. There are several companies that make wireless phones. As with any complementary product purchase ask two questions – Obviously – what make, brand and release are you compatible Second – what features will or will not be available
The second is most important. While they may be compatible and the phone will "work" make sure it is not in a limited capacity. I would suggest working with the 3Com partners as the equipment is already tested with 3Com equipment and will provide you with the heartiest environment.
