Any SIP compatible piece of hardware should be compatible with the Gizmo5 service. However, we do not provide support for those other than those that we have sold in the past.

To configure a device you need the following information:

• SIP Proxy: proxy01.sipphone.com:5060
• STUN server: stun01.sipphone.com:3478
• Username: Your SIP number, found by dialing ** in Gizmo5 Password:
• Your password Codecs: iLBC, GSM, g711a, and g711u (Gizmo5 uses other codecs as well, but you won't find them in your hardware settings)

Note: If your device includes setup fields for an "Outbound Proxy" leave all of those fields blank.

Gizmo5 does not provide an outbound proxy service and your device won't be able to connect to our network if you put anything into those fields. Due to the wide variety of SIP-compatible hardware devices on the market, we cannot offer more specific instructions for them. Gizmo5's parent company previously sold the Grandstream HT-286 and HT-486 adapters, so you can get setup information for those devices at the links in this sentence.
