Hi,

I have a question about indexing in section B.1. PBX Voicemail call floww.

   F6 INVITE Example.com -> VM
   <snip/>
   History-Info: <sip:[email-masked];\
                      target=sip:[email-masked];cause=408>\
                      index=1.3;mp=1.2

This mp-value is "1.2".
If this HI is mapped from 1.2, should the index be 1.2.x?
Or, if this is mapped from "1"(ie [email-masked]), should
the mp-value be "1"?

Regards,
Shinji.
