We are wanting to configure a pair of Cisco SPA303s to support hot line functionality. I.E. When the phone goes offhook, it immediately dials a particular number without the user having to press any buttons. We are using SIP as the signalling protocol.
According to the datasheet, this is possible (perhaps only for SCCP though?):
However, I can't figure out how to do it. I have scoured the phone and web interface options and can't find anything. I have also checked the XML configuration template for the SPA30X and 50X phones. I can't figure out which option allows me to do this.
Has anyone else done this before? Would they mind sharing how they did it?
I have tried searching these forums and Google to no avail. If I've missed something, please point me in the right direction.
