Usage

Presence State Publishing

Follow the instructions given in the User Manual.

SIP Package: when you change your presence state to "Lunch", your phone will send the server a SIP package similar to:

PUBLISH sip:431@192.168.10.59 SIP/2.0
Via: SIP/2.0/UDP 10.10.12.136:2051;branch=z9hG4bK-i9mwzvn9bqv7;rport

Contact List

To be able to build a contact list on your snom phone, your server must support Resource Lists as defined in RFC 4662 (http://www.ietf.org/rfc/rfc4662.txt)

Here is an example on how you can build a contact list of 3 contacts.

First we set:

• Contact List to 'on'
• Contact List URI to '100@10.10.12.190'

• Next, the server sends a NOTIFY contaning the contact list and the states for each contact:

Now if you set one of the Sx key to open the Contacts list, the list will look something like this:
