IP address

By default the base unit picks up an IP address using DHCP. You can find the IP address from the Handset: Press OK – Select the ‘i’ icon (Status), select ‘Base’ - the IP will be shown.

Yealink and Voiceless

On the web interface, go to:

Settings -> Telephony -> Edit 1, Show Advanced Settings

Gigaset Yealink Settings
Setting	Value
Connection Name or Number	AAISP (Or whatever you like)
Authentication Name	Your Number (+44...)
Authentication Password	Your Password
Username	Your Number (+44...)
Domain	voiceless.aa.net.uk
Proxy Server Address	blank
Registration server	voiceless.aa.net.uk
Registration refresh time	180

Then you'll need to assign this account to a handset for incoming calls, this is set under

Settings -> Telephony -> Number Assignment

Don't forget to secure the base station with a new PIN:

Settings -> Management -> Miscellaneous -> New Pin

Audio settings

In menu:

Settings -> Telephony -> Audio" select "Voice Quality -> Own Codec preference".

For "IP1" (Or whatever you call the AAISP account) remove all codecs except "G.711 a law". This setting will generally give the best audio quality.

Other settings

If there are problems with recognition of DTMF tones by other systems consider setting "RFC2833" and avoid using "Audio". in the setting:

Settings -> Telephony -> Advanced Settings -> RFC2833

Check that the Number Plan/Assignment is set to use the VoIP rather than the fixed (pstn) line:

Settings - Number Assignment Set the VoIP for outgoing, and set the others to suit...

It may not say the above and Automatic negotiation of DTMF transmission will need to be Yes

Set the Tone Pattern to be UK:

Settings -> Management -> Local Settings -> Tone Pattern=United Kingdom

You may want to remove, or edit, the 'Info Services' - this is the information such as weather and so in that can be displayed on the screen:

Settings - Info Services

Quirks

We have seen odd things with a S685IP (Firmware version: 022270000000 / 043.00) where it would register, but not pass calls. A reboot of the base station fixed this.

Firewall & Security

You will also want to set up firewall rules, as per the VoIP Firewall page.
Also see the VoIP Security page for information about securing your VoIP service.
