As enterprises continue to evolve their communications infrastructures into a pure SIP/VoIP environment, they often discover that there is still the need to connect older non-VoIP equipment to their VoIP infrastructure or directly to the PSTN. Many of these older, but necessary endpoints (i.e. fax machines, postage machines, alarm systems) simply will not function reliably over a VoIP network.
There may also be instances where it is more cost effective to use a “Plain Old Telephone” as an endpoint on a VoIP network, rather than an expensive VoIP phone.
