The BT Diverse 7100 is an additional handset and charger that can be used to expand upon an existing Diverse system. Adding extra BT Diverse 7100 handsets is a very easy way to get a phone into locations that don’t normally have one. The BT Diverse 7100 additional handset and charger is the extra cordless phone for the BT Diverse 7110 and the BT Diverse 7150. In total both of these phones can have up to 5 handsets working at once so up to 4 more Diverse 7100 phones can be added. When purchased the BT Diverse 7100 cordless phone is also supplied with its own drop in charger. This not only charges up the phone but also gives it a handy stand to sit in when not in use. As the BT Diverse 7100 handset is designed to work with the 7110 and 7150 phones it has the same features. For example built in is a 100 name and number directory to store contacts that can be copied from the original phones. Once set up each of the BT Diverse 7100 cordless phones has the ability to answer a call and transfer over to other handsets. It is even possible to make an internal call between the phones and also name them differently as well. It is possible to wall mount the charger and both the Diverse 7100 handset and charger are finished in a black colour.
