Question.

I have this block of code at the beginning of route block:

        if(is_ip($td))

        {

                xlog("L_INFO", "[$ci][$mi][CSeq $cs] IP detected in To domain.  Resolving. \n");

                exec_avp("host $td | awk '{print substr($$5, 1, length($$5)-1)}'", "$avp(s:newtd)");

                xlog("L_INFO", "[$ci][$mi][CSeq $cs] new newtd = $avp(s:newtd)");

                $td = $avp(s:newtd);

                xlog("L_INFO", "[$ci][$mi][CSeq $cs] new td = $td");

        }

but $td never updates.

Apr 11 18:26:00 sjomaintpsg50 /usr/local/sbin/kamailio[6475]: INFO: <script>: [8ROWdUOINx][1][CSeq 20] IP detected in To domain.  Resolving. 

Apr 11 18:26:00 sjomaintpsg50 /usr/local/sbin/kamailio[6475]: INFO: <script>: [8ROWdUOINx][1][CSeq 20] new newtd = sjomaintpsg50.fuzemeeting.com

Apr 11 18:26:00 sjomaintpsg50 /usr/local/sbin/kamailio[6475]: INFO: <script>: [8ROWdUOINx][1][CSeq 20] new td = 206.81.191.30

Is there a reason why?
