Landlines problem

[Mommomf]

Recently went back to Verizon FIOS but now they have digital phone service and I can't make outgoing calls.  When I was with Verizon before it went digital, I had no problem dialing out.  I had a service rep here and he checked all lines and everything was fine.  He thought it was a compatibility problem with the digital and my phones.  He discovered that I could make outgoing calls if I switched to pulse.  He said I shouldn't have to do this.  So, he had the service rebooted but after a couple successful outgoing calls, I had to put it back to pulse.  Does anyone find they have to buy new digital phones?  The service rep says I shouldn't have to.
