x710 Phone Contacts Won't Dial?

[pmyers]

When I try to dial using the contacts I often just get a fast busy signal.

At first I thought it would dial local and not long distance but both seem to give me busy signals (most) or operator 42 messages. Once in a while it dials and goes thru.

 

If I pick up the phone and dial from the phone it goes thru and the x710 will connect to the phone so I can talk over the hands free.

 

Anyone had and solved this problem?

 

Thanks
