Hello,

the value for $hdr(P-Asserted-Identity) is not a SIP URI, bit a To-body like format, so you have to use {tobody.user} instead of {uri.user}. Or use $ai instead of $hdr(...) with the uri transformation.

Cheers,
Daniel

Hello,

Hi

We are experiencing issue with python script KSR.pv.get using branch 5.0.2 as it fails "unable to get pv value"

Example Code:
if KSR.pv.get("$ai"):
                              fromid = KSR.pv.get("$(hdr(P-Asserted-Identity){uri.user})")

Error:

Is anybody have any idea how to workaround?

Many Thanks
