Seems like a valid bug report.
I think an easy workaround would be to always use name-addr syntax.

The bad syntax is located in the "To" header field.
According to the RFC 3261 section 25.1, the grammar of the To header
field is as follow:
To = ( "To" / "t" ) HCOLON ( name-addr
/ addr-spec ) *( SEMI to-param )
name-addr = [ display-name ] LAQUOT addr-spec RAQUOT
addr-spec = SIP-URI / SIPS-URI / absoluteURI
to-param = tag-param / generic-param
The RFC 3261 section 20.10 explains that:
Even if the "display-name" is empty, the "name-addr" form MUST be
used if the "addr-spec" contains a comma, semicolon, or question
mark. There may or may not be LWS between the display-name and the
"<".
As the "addr-spec" */sip:anonymous;cpc=ordinary@192.168.225.2/*
contains a semicolon, it means that the "name-addr" form must be used.
The "To" header field should be encoded as follow:
*/To: <sip:anonymous;cpc=ordinary@192.168.225.2>;tag=01e3a8c0-c1c2-t-1/*
