Hi Alex,
Right now there are no specific variables to access that info (only if
we develop some new once).
what you can explore is to use strings ops to get the info you need from
the header body ($hdr() ) . Try:
1. string transformations :
http://www.opensips.org/Resources/DocsCoreTran16#toc1
2. regexp based substs:
http://www.opensips.org/html/docs/modules/1.6.x/avpops.html#id271693
Regards,
Bogdan
