Starting from a factory reset, the following items need to be set using the web server in the base unit.
= IP address
By default the base unit picks up an IP address using DHCP. This can be over-ridden by connecting to "Settings -> IP Configuration", selecting "Static" and filling in the address details as required. Then click on the "Set" button.
=N300 and Voiceless=
[[File:N300settings.png|thumb|click to view settings]]
On the web interface, go to:
Settings - Telephony - Edit 1, Show Advanced Settings
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
=== Audio settings
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 is set to use the VoIP rather than the fixed (pstn) line
It may not say the above and Automatic negotiation of DTMF transmission will need to be Yes
== 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==
