Hi Erik, Hi Tom,
thanks for this question / hint :)
We just tried (not a long term test and not Q/A approved) it with the OCS Edition firmware and the funtionality is still available like in the standard SIP firmware.
In the webinterface you go to Action URL settings
"https://phone-ip-adress/action.htm"
under: "On offhook:" you enter:
"https://phone-ip-adress/command.htm?number=Extension"
Please use the local-host IP (127.0.0.1), if your webinterface is secured (by a user and password, as recommended) so the phones does not need to authenticate to itself. E.g.:
"https://127.0.0.1/command.htm?number=123"
The number will be normalized according to the OCS/Lync dialplan, like you would dial from the keypad.
A hint: After you saved the setting you will find it listed unter the Settings page of the phone:
"https://phone-ip-adress/settings.htm"
Like quite each and every setting on this page can be mass-provisioned, you can provision this settting too.
The "Click here to save..." options on top of the page, allows you to easily creating a kind of "master/template" phone config file, while removing all
indivdual settings from the export.
More details on provision / mass deployment can be found here: http://wiki.snom.com/Category:Auto_Provisioning
and especially for the snom OCS edition you will find the Administrator Guide PDF inside
your personal menu
after your registration
and access granted.
Thanks and greeting from Berlin,
Jan
