As discussed here:

http://www.dclug.org.uk/archive/2004/02/msg00034.html
you can use a network cable for telephones 

Telephone cable has 6 wires (3 pairs), cat5 has eight (4 pairs).

Regular ethernet uses 2 pairs one for TX and one for RX. Typically the
orange and green pairs. The other pairs will not be connected to
anything, in some cases the connectors for them are absent in the sockets.
