Q: Are the DuraFon Pro handsets compatible with the DuraFon-SIP system?

A: No, they are not. Similarly, a DuraFon-SIP handset will not work on a DuraFon Pro system.

Q: Is the DuraFon-SIP a multi-base system?

A: Not by design. Each DuraFon-SIP base station can support up to 10 handsets. Handsets registered to other DuraFon-SIP base stations can be called using internal PBX extension-to-extension calls, but the 2-Way Intercom and "Push-to-Talk" features do not work between handsets registered to different base units. You will also need to ensure that base stations will need to be at least 30 feet apart to avoid interference.

Q: Does the DuraFon-SIP support TAP and text messaging?

A: No, it does not.

Q: Can a DuraFon-SIP handset receive a phone call during a 2-Way Intercom call conversation?
