1) to always use my account name in the "From" header, so I have to use header header rewriting to achieve this
2) to set the "P-Preferred-Identity" header to change the caller id (as From cannot be used due to point 1)
Now the header rewriting for 1) works fine, but 2) is bit more complicated, as I need to fetch the source number (ideally before it has been modified) and then use it in a new header line. (aka "copy contents from one header to another header in an outgoing SIP message")
From the "Conditional Header Manipulation of SIP Headers" document I would have assumed that the following works:
voice class sip-profiles 101
request INVITE peer-header sip From copy ".*<sip:(.*)@" u01
I've opened a TAC case and the problem was simple.
Modifying an existing heade works a single SIP leg in general but copying headers, working with variables requires multiple SIP legs, one to fill the variable and another to add/modify the header with its content.
As I only had a single SIP leg this cannot work.
Nevertheless, I've managed (again with TAC help) to get the desried functionality by adding
