Indeed.. Happened to me once.

Unfortunately I'm so used to dialing zero, I've done it from other
phones by accident. I went to make an International call, added the
zero and ended up with 00011.

I done two things:
First change (in the Asterisk source) channels/chan_sip.c:
#define CALLERID_UNKNOWN        "Unknown"
static char default_callerid[AST_MAX_EXTENSION] = "Unknown";

Then, my extension logic has:

exten => xxxxxxxx,1,NoOp
exten => xxxxxxxx,2,SetCallerID(Outside Call <0${CALLERIDNUM}>)
exten => xxxxxxxx,3,GotoIf,$[${CALLERIDNUM} = 000]?200:4
exten => xxxxxxxx,4,Goto(local-extensions,xxxx,1)
exten => xxxxxxxx,200,SetCallerID(Outside Call <>)
exten => xxxxxxxx,201,Goto(4)

It does two things - prefixes the caller number with '0', replaces the
name with "Outside Call" (so I know the call came from outside).

If it's a public number, the phones (at least those that support cid
name+number) will display Outside Call and the number.

If it's a private number, the phones display Outside Call and Unknown.

This all works fine on a Telstra Onramp/ISDN 2 (BRI). I'm not sure
about Onramp/ISDN 10/20/30 (PRI)
