Actually it works. I have left an extra call to $du = "sip:" + $rd + ":" + $rp + ";transport=udp"; later in my script and since ds_select_dst() changes the $du but not the $ru, I was actually messing with the value of $du by doing: ds_select_dst() $du = "sip:" + $dd + ":" + $dp + ";transport=udp"; $du = "sip:" + $rd + ":" + $rp + ";transport=udp"; Sorry for the wrong report.
