Why? I think you have misunderstood something, but I am not sure what.
The pattern "(tell(?C1))" matches just "tell". Why do you think it
should match "tellcall"?

I do not understand anything about "$0=ENTITY:callout:ADV/ADV" because
that is not part of PCRE.
The (?C1) part of the pattern passes control to your callout function,
with information about what it has matched in the pattern. However, all
that the function can do is either say "carry on" (return code 0) or
"stop". Are you perhaps expecting something else?
