Introduction

IPv6 is supported in all stable frimware beginning release 8.7.5, with some exceptions (snom300/320/360/370/710, PA1, Meetingpoint). For more information, please read the Release Notes for new firmware releases. Current Release (Nov. 2015): FW 8.7.5.35 Release Notes and Download Links.

snom3xx, PA1 and Meetingpoint are not supported due to technical limitations.

Please find below an overview of how to set up IPv6 on your phone.

Using IPv6

Note: Before 8.7.5.35 Release, it was only supported in the BETA version 8.7.5.8

In order to use the IPv6 mode, you need to go to the advanced settings and click on More Controls next IPv6.

Now you need to choose between autoconfiguration or on.
- Autoconfiguration means: Only SLAAC (Stateless Address AutoConfiguration is enabled)
- On means: DHCPv6 and SLAAC is enabled

Now you need to save the changes and reboot your phone:

During bootup you should notice that the phone also acquired an IPv6 address:

Now you can open the phone’s webinterface via IPv6:

Under the tab Identity you can enter your credentials and an IPv6 enabled SIP-server:

IPv6 on the PC port

Even if your phone is using an IPv4 address, you can connect a IPv6 host on the PC port. The phone acts only as a switch from PC to NET port. This means that if the host sends IPv6 packets to the phone on the PC port, the packets are sent further through the NET port of the phone, with no change to the IP headers.
