Re: reading out "response" and "integrity-protected" from "Authorization" header field

Hello,

Use transformation with the header PV:

  *   For more complex headers https://www.kamailio.org/wikidocs/cookbooks/6.0.x/transformations/#tobodyparams

Cheers,

Henning

Subject: [SR-Users] reading out "response" and "integrity-protected" from "Authorization" header field

Hi all,

Again an IMS question.

The 3GPP TS 24.229 specifies some additional parameters for the "Authorization" header field in REGISTER requests, e.g. the "integrity-protected" parameter and the "response" parameter.

Now the question: is it the only way to read out these parameters from the "Authorization" header field, by implementing new pseudo variables, e.g. $aip and $are, or is there an easy way using $hdr() from the configuration?

I want to avoid sophisticated regular expressions.

Thanks,
Christoph
