[Serusers] Deteriming if caller=callee

[Steve Blair]

Hello:

  I am trying determine if the called number equals the called number
in my SER 0.8.14 stable proxy. I've tried several combinations of
check_to and check_from without success. Mailing lists articles on
this topic seem to refer to features in development or 0.9 branches.
Is it possible to check for this condition in the above release? If so
a hint on how to do it would help.

Thanks,Steve
