Well, there's a few things that may be at play here.  Note that in this 
dial peer we have "clid restrict", so in your dial-peer if you're using 
"*" to indicate that you want to suppress outbound clid you'd have 
something like

dial-peer voice 871 pots
trunkgroup Local 1
trunkgroup FXO 3
description Local 7-digit pattern - use Local PRI first, then FXO
preference 1
destination-pattern *8[2-9]......
clid restrict
forward-digits 7

In my deployment, I actually suppress clid for all outbound dial-peers, 
but have a *8T destination pattern / dial-peer that has a trunkgroup FXO 
so that those calls go out the analog.

Of course, the other issue may be that your PSTN provider is ignoring 
the fact that you're suppressing clid and stuffing it in anyways, so you 
may want to talk to them.
