Existing Handsets
Changing and upgrading mobile phones can be a major cost to a business and many business voice mobility offerings, such as dual GSM VoIP and DECT solutions, mean that specialised phone sets are required.
Private Mobile eXchange (PMX) supports any 2G or 3G device over GSM and any PBX, either TDM or IP based. Standard GSM mobile phones will work because PMN adheres to GSM standards for call control. This includes all telephones produced since 2000 by all the major manufacturers. Tri band mobiles have been successfully tested.
