Nope. They absolutely must leave me a voicemail. I am deaf, but I do have my own mobile phone and the ability to get voicemail on it. I can't listen to my voicemail myself, so I have to have a relay operator do it for me. It's even specifically stated in my voicemail greeting. Something like "Hey there! You've reached Allison. If you are someone calling me, please text me at the same number you're calling, or leave me a voicemail. If you're a place of business calling me, please leave me a voicemail and I will get back to you ASAP." It works.
