How to setup presence?
Presence works best on snom phones, using version 7 of their firmware (http://wiki.snom.com/Firmware/V7/ReleaseLaunch), but we have also tested with the Grandstream GXP2000 and GXP2020.
== Snom Phones
On a Snom, go to the function keys section, and on the P1 -> P7 light options,
1/ select your extension from the drop down menu as the source (e.g. 23455678@newsip.voipadvantage.co.uk)
2/ Choose the “Extension” type
3/ Enter the other extension you wish to monitor. e.g.
Snoms / the system works peer2peer, so you appear to need a matching entry on the other side. You can view the current “subscriptions” each phone has using the “Subscriptions” option.
Shared Line – with this now you can implement a proper “shared line”, and have multiple phones registered on the same extension. If you do it normally, then it should ‘just work’, but if you enable the shared line function on the Snom phones “Identity 1 -> SIP”, then, if you are on the phone on one of the handsets, the extension should appear busy if some one else rings in.
You can also enable “publish presence” under advanced settings “sip”.
Finally, if you are monitoring an extension, Group Call Pickup should be possible, by pushing the relevant button when the other extension is receiving a call.
