Configure Call-Forwarding for a station in sip.conf

I have a question which you guys will be able to answer very quick I suppose.

Is it possible to configure an immediate call-forwarding for a station directly with the station context in the sip.conf file?

The collegue who was using the station/extension has left and we need to make sure that those calls are re-directed to a different extension.

Thanks for your help

Not in sip.conf but you can do it very easily in extensions.conf. Just set up an extension for that phone number and have it ring on the sip device you wish to forward.
