Can IVR facility to landline be set up?
My office works from 10 AM to 5.30 PM. I am in need of some instrument/software/accessory, which must work like answering machine, if anybody calls before 10 AM or after 5.30 PM, an automatic voice message is to be played announcing a message like "This telephone works from 10 AM to 5.30 PM only on working days".
