We are trying to write a normalization script to change the outbound
calling name.  We have several companies that are tenants as well, so
changing it just on the trunk is not an option since all tenants utilize
the same SIP trunk.  We want to make the change based on the calling
number.  Here is the script that we have come up with, but it does not
seem to be working.  Also the trace is enabled on both the script and
the trunk, but we are not seeing any trace in the sdi when we make
calls.  Any help or suggestions would be greatly appreciated.
