Freeswitch is so much better than my customers deserve.

I have the DialPlan set up nicely so they can dial *72 to forward all DID calls to their answering service and *73 to turn it off.  Today she Dialed *72 to turn it off 4 different times, and since that is the code to turn it on --- it did NOT turn off.  She was livid and sent me hate mail about how “terrible IP phones are and they never work …”

I even consoled her saying how *72 and *73 have no inherent indicators to show which means on and off.   I have offered the obvious solutions of SPEED DIAL buttons that are labeled “Enable” and “Disable”.

Now my question.  Anyone have any ideas how to use a line button, or possibly MWI to indicate that lines are forwarded (a db value).  MWI is clearly in use so line button is my preference, but if MWI had a flash function, etc????  I have unused line buttons – How can I make them show busy (like shared call appearance) from the switch?  Maybe a dummy user/extension I do something clever with?

If it matters the phones are Cisco 504G (4 line).

Thanks in advance,

Sean
