You seriously over-estimate the computing power that gets thrown at
telephony.  Motorola's (Well, DSC made the hardware) cell switch was driven
by Z-80s until just a few years ago, when the upgrade was made to PPC chips.
Of course, the RP-1 ran the Z80 code in emulation mode.  Base stations have
less computing power than that, but it tends to purpose built hardware.  
(Linux is unlikely -- (at least) two ofhte bigger infrastructure suppliers
are UNIX source licensees.)
