I have a smilar problem : I have a default context for an interface,
where I'd like to prefix all incoming calls DID numbers (basically,
the telco sends the last 4 digits dialed, I want to fully qualify my
E164 number before doing extensions processing).

I don't know much (yet!) about Asterisk, so I thought something like 

exten => s,1,Prefix(3312345)
include => my_local_e164_extensions

would do the trick. Unfortunatly, if the ${EXTEN} was 6060 at that
time, I get a new extension as s6060 (instead of 33123456060). Is it
supposed to be this way ?

So instead I had to do something like

exten => _XXXX,1,Prefix(3312345)
include => my_local_e164_extension

which works fine, except that now I'm at the "2" level in the context,
and I had to modify my_local_e164 extension context accordingly.

Does somebody know of a better way to do it ?

Thanks.
