poe issue

Guys

if i take my 7945 ip phone to switch room and connect it . its
getting poe and registering fine .

but when i go out to cubicle where user is sitting and connect it over
to same port . (cable patched by patch pannel ) .. their is no poe.

when i connect 7912 .. smaller ip phone ..it get poe from the cubicle
. This is strange .

both phones has different poe needs ? it is depondent on cable cat 5, 6
etc ?

is their any way to boost up poe from the switchport ?

i tried some options

power inline auto ....
shut no shut
reload switch ...
