Considering you might have multiple header fields all comma-separated in
one header, to access the last uri you'd have to do something like:

$(hdr(Record-Route)[-1]{s.select,-1,,}{nameaddr.uri});

try with $(hdr(Record-Route)[-1]).. it works for us (though, with
another header name).

[SR-Users] Select last URI from Record-Route

[Ilie Soltanici]

Hi,

Try $(hdr(Record-Route)[-1]), to extract URI only you can
use: $(hdr(Record-Route)[0]{nameaddr.uri})

Hi Carsten,

Thanks for the suggestion but it looks like that takes the URI from the
route header not record-route. I tested to be sure but the assignment fails
because there is no route header.

Hi,

Check for $route_uri, we use it to determine the session-case (no or Mt) on
the Proxy-CSCF.

Thanks,
Carsten

The simple answer to that is it's a last ditch effort to look up an AOR
record on a reply but it's part of other logic we use to establish direct
media.

I do have to wonder: what do you need to do that for? What are you
trying to accomplish?

[SR-Users] Select last URI from Record-Route

[John Petrini]

Hello list,

Does anyone how I can extract the last URI from a compact Record-Route
header?

I've tried using a negative index in the parameter of my select but it
returns the first URI in the header instead of the last.

$var(rr_last_uri) = @record_route.uri[-1];

Maybe there's another way instead of using selects?

Thanks,

John
