Hi Robert,
As from SIP perspective both TO and FROM hdrs have the same syntax,
internally OpenSIPS uses the same function "parse_to()" for parsing both
hdrs. So, we are all good here :)

While running opensips in debug mode I noticed that for initial
requests of dialog creating methods the debug logs were showing a To
tag where none actually exists. The tag displayed was actually the
From tag.
