Hi
You could try subst_hf() from textops to do it. I didn't find any
simpler way to do it. It may be possible to do this with URI
transformations, too, but I didn't experiment with those.
subst_hf("Record-Route", "/;zoink=[^;>]*//", "a");
It changed these header fields to these.
Record-Route:
<sip:10.25.10.1;r2=on;lr;ftag=gK002f29d3;zoink=freddie;yoink=meatloaf>
Record-Route: <sip:10.17.12.2;r2=on;lr;ftag=gK002f29d3;zoink=freddie>
Record-Route: <sip:10.25.10.1;r2=on;lr;ftag=gK002f29d3;yoink=meatloaf>
Record-Route: <sip:10.17.12.2;r2=on;lr;ftag=gK002f29d3>
By the way, the rr parameter for adding ftag to the RR header fields
can later be used to see which direction (the is_direction() function)
the request is going in, so you may not even need to change the
Record-Route values if you use that.

Hi
Is there a way to remove an param from the top most rr header?
I add a rr param towards the B CPE to store some information which is
sent back on the rr header of the reply from B.
So far this is what is intended and I also get this param in subsequent
route headers from messages created by B and as the route header are
remove towards A, this works fine.
Unfortunately, in a case of a reply, the parameter is passed to A
which is then sending back the param in the route header which would
make it somehow complicated to figure out which side sent that
parameter. I'm only interested if sent from B.
So I wonder, is there a way to delete a rr param on replies to make
sure I don't get it back in the ACK to the reply?
