Dear All, I'm trying the following and i get error: $var(new_uri) = "sip:" +$avp(s:term_prefix) +$rU +"@" +$avp(s:gw_address); rewriteuri=($var(new_uri)); OR append_branch($var(new_uri)); But it seems that it does not like the variable. The documentation says that rewriteuri get a string so i don't understand why does not work. Do you have any ideas on this ? Cheers Alex

Hi, Thanks for the replay. I already tried the $ru with $var and it works fine but the main problem is the append_branch. I'm trying to create a redirect function with the append_branch dynamically filled in. Any suggestion on that? Thanks Alex On Fri, May 6, 2011 at 6:31 PM, Iñaki Baz Castillo <ibc(a)aliax.net> wrote:

You are not passing a string to erwriteuri() function, but a pseudo-variable containing a string as value. It's not the same (not at least in kamailio/sip-router configuration DSL language). However you can use: $ru = $var(new_uri); as $ru pseudo-variable (request URI) does allow dynamic assignement. -- Iñaki Baz Castillo <ibc(a)aliax.net> _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

Just set the RURI to the value that you want and then call append_brach(). Everything that's in RURI will be appended as a new branch. After that, reset the RURI to it's original value: revert_uri(). Regards, Ovidiu Sas On Sat, May 7, 2011 at 12:37 PM, alex pappas <rebel.pappas(a)gmail.com> wrote:
