So we had no dial tone... our phones were old so I replaced them - the dial tone worked - then, no dial tone again. Reset dpt - dial tone came back - then no dial tone again. Removed battery from dpt - dial tone comes back again - then later no dial tone again. Did nothing - then the dial tone came back anyway, but now it sounds like we have voice mail for the first few seconds. The wiring looks good to me and was set up by a shaw installer a couple years ago.
