I am using Obi with Vestalink and I ported my phone number. If I am on the phone I want the next person who calls my number to get a busy signal is it possible for it to do that? I don't want to use call waiting or voice mail.
If I turn Call Waiting and Voicemail off in Vestalink I get a message that says "Nobody is available to take your call at the moments...."
Thanks
