[asterisk-users] Is STP wire decent for analog phones?

[Steve Prior]

I've got a run of Shielded Twisted Pair (4 conductors) which used to be 
a Token Ring Network drop and I'm not using it anymore.  Would it be 
decent to replace the ends with normal analog phone connectors and use 
it for a phone extension, or is STP unsuitable for that?

Thanks
Steve
