I knew this question was going to lead to trouble!
Okay, here goes.
First thing, if the incoming call digit string will be matched to the
destination-pattern of a VoX dial-peer, there is no prefix or forward
command available. In a VoX dial-peer you are mapping a telephone address
(the destination-pattern) to a Network address (session target with Layer
2 or Layer 3 address). This is your voice routing table! This is the
logical routing plan you created when you designed this voice network.
This is a static routing table you created. Why would you map an address
one way, then try to modify it before you sent it to the ultimate
destination? Dial plans are simply static routing tables. There is no
EIGRP for voice networks, yet.
Digit stripping happens ONLY on POTS dial-peers. Digits described
explicitly (333 in 333) are consumed during the digit analysis. The
prefix command can be used to replace the consumed digits, or the forward
digits command can direct that X number of digits are to be preserved and
sent across the POTS line once it is active.
The EM should do what you want if you want to only send 4 digits to the
other end.
The VoIP dial-peer will send all digits that match the
destination-pattern statement.
This all depends on what you are trying accomplish. This isn't clear
because you are mixing FXOs and EMs which you can't do.
Maybe this will get you aimed in the right direction. Feel free to email
me with what you are trying to do. the configuration may be very simple.

Hello All,
When FXO receives a phone call, it strips out corresponding called-number
that matches destination pattern settings.. For instance,
If call string that matches 333 , it will strip 333 and pass on last
four digit. IF there is next hop voip router only sees last four digit.
(Isn't that correct?.
Now, how can we make that happen for EM card? (VIC-2EM)? digit-strip
is
enabled by default, but next router only sees 333- instead of .
Help me out. Thank you.
