When I am talking on my iPhone 4S I can hear another call beeping in, but it will not let me switch over to them, nor tell me who is calling. Sometimes it will say "multiple calls" at the top, but it doesn't give me the option of switching over to the new call like I use to be able to. So I hang up with my first call to try to see who is calling and there isn't any missed calls. Unless the caller leaves me a voicemail, I do not know who is calling. How do I fix this? It just started yesterday (10/3/12)
I went to:
But there is no option for Call Waiting. Should there be?
I cannot figure out how to fix this. Due to my line of work, I have to have this feature working properly. Can anyone help me?
Thanks! :smileyhappy:
