If I set $ru in config file and then print $ru to log, the new value is printed. If I do the same with $fu, the old value is printed.
I haven't found in Pseudo-Variables Wiki any documentation about this. Does it exist somewhere else?

Operations to change the headers and body are not applied immediately:

OK, got it. What makes $ru special, i.e., why that is applied immediately?

Hello Juha,
The first line of a SIP request is parsed and kept separately from the rest of the SIP message. Because of this, it is easy to apply instant changes to it. This is what I remember checking the code long time ago, it might not be 100% accurate.
Hope this helps, -ovidiu

Perhaps it would best to explicitly tell on Pseudo-Variables Wiki page, which R/W pseudo "variables" are not really variables in the sense that setting of the value does not change its value.
Are there others than these three: $fd, $fu, $fU. If not, I can add a note to their entries.

Should be the same for To header.

I looked at pv_core.c, and based on that these are header R/W variables:
$tu, $tU, $td, $tn, $fu, $fU, $fd, $fn
I updated the Wiki page accordingly.
