[HELP] Programming buttons on Polycom SoundPoint IP 601

Everything I have read indicates that the buttons on the Polycom SoundPoint IP series can be reprogrammed. Unfortunately I have yet to see anything explaining exactly how this works. Right now I have an intercom system setup where you can dial 6X where X is the 1 digit intercom extension of the phone. What I’d like to do is use the bottom line button for an intercom button. Ideally I’d like the following:

  • Label the button with “Intercom”
  • When the button is pressed give a dial tone and display somewhere on the phone “Enter Intercom Extension”
  • After the user enters the single intercom number (ie 1, not 61) send 6X to Asterisk where X is the number entered

Is this even remotely possible?
