Hi,
found the problem. The device does sometimes use User-Agent and sometimes Server.
Is it better to use $hdr() or the Search() function?
I use this to check for the User-Agent and then to do a "fix_nated_sdp()" (in route[] and onreply[]) because I am not really sure, if the fix_nated_sdp() could break something. Or should kamailio break nothing here? Sometimes the User-Agent/Server is missing in Session-Progress 183. Therefore a "global" fix_nated_sdp() would be nice to have.
Best regards, Bernhard

Hi,
could it be, that the $ua pseudo variable is not set within in a onreply
route? (Version 3.1). no, should be set, there was no change in this regard for quite long time. Can you sent the sip reply plus log with debug=3?
What is the best alternative for that? Search()?
The alternative is $hdr(User-Agent) which is practically returning the same value as $ua, using generic header search mechanism.

$hdr() should be faster and more accurate result, working as well with short names for headers -- e.g., $hdr(Call-Id) will match both long and short versions:
Call-ID: .... i: ...
We search, be sure you do the expression in the way you won't match the value in another header or body.
