VoIP Phones - Gigaset 900

Back up to the VoIP Configuring page
From AAISP Support Site

Gigaset 700 and 900 Series



These phones do support single-stack IPv6 as well as single-stack IPv4. We have tested both, and with the IPv6 version there was lag when making calls, e.g., dial a number and there is noticeable lag before it starts talking SIP to set the call up.

IPv6 On Gigaset Phones

The firmware tested supports IPv6!


They are only single stack, but they do work. The firmware tested is laggy though, as in dialing a number takes a few seconds before it starts talking SIP to initiate the call.
