By using the 900 MHz frequency, there is also no need to worry about the DuraFon-SIP receiving or causing interference to existing 2.4 GHz and 5 GHz Wi-Fi.

The DuraFon-SIP's Handset provides direct handset-to-handset communication without going through the Base Station for quick contact with specific users without group chatter.

DuraFon-SIP offers the favored, "Push-to-Talk" feature through the Handset's Broadcast button, allowing users to create one-way communications for 1-to-All or 1-to-A Handset Group for instant response without the wait.

Support for both SIP and PSTN lines permit the connection of the Base Station to a legacy PBX, IP-PBX or preference service provider and gives users up to four talk paths via four digital calls or three digital calls and one analog line.
