Cut Box circuit help

[M.Williston]

I need help with designing a circuit to help me cutting customers telephones
lines from one central office to another. The basic idea is to be able to
hear the ANI (automated number identification) from the test line on my talk
line. My TALK LINE is a normal phone connection to a facilities tech.. I
want to dial the ANI with my DIALER on the TEST LINE and be able to hear the
number call-out from that line on my talk line.

I have a working circuit I am using now but the volume is very low coming
from the test line. I am using .01 uf caps (200v) as C1 and C2 with a 600ohm
1:1 isolation transformer. You can see my circuit here:

I may be way off track but my reasoning behind this circuit design is to use
the isolation transformer to separate the power sources from two central
offices and the two capacitors to block DC current to NOT take the phones
off hook.

I am not worried about voltage or current protection anywhere in this
circuit as all the end equipment is already protected..

Any help would be appreciated..
Thanks, MarkW
