Based on the specifications for Ethernet/Fast Ethernet over twisted pair, the commonly accepted maximum distance between an Ethernet transmitter and receiver is 100 meters. In my experience I have found that if you go much beyond that, you will have issues. With Fast Ethernet I have seen distances beyond 100 meters but 190 meters would be well outside of what I have seen work.
In your case, you are almost twice that maximum distance. You need to shorten that distance in some way. If you are dropping a single phone then placing a local switch wouldn't make much sense. There is a good thread on this exact topic here:

If you have multiple phones in the location, then you may want to run a single fiber pair and put in a local switch.
HTH.
