[Kamailio-Users] script var or avp in ds_select_dst (dispatcher)?

[Robert McGilvray]

Turns out this is caused by passing ds_select_dst a string instead of an
int. 

 

$var(test) = 30; works

$var(test) = "30"; doesn't work

 

The attrs field in dialplan is a string. Converting it to an int with
{s.int} worked for me.

Subject: [Kamailio-Users] script var or avp in ds_select_dst
(dispatcher)?

 

 

Can someone please confirm that I cannot use a script var or avp in the
set field when calling ds_select_dst from the dispatcher module? I'm
trying to use dialplan to return a gateway group via attr, then call
ds_select_dst with that but get the following error in my logs. If this
is my problem are there any workarounds?  The goal is to call
ds_select_dst with a dynamic value. Example -
ds_select_dst("$var(dpattr)", "0")

 

 Jun 24 14:50:49 [1125] ERROR:core:fixup_get_ivalue: no valid PV value
found (error in scripts)

Jun 24 14:50:49 [1125] ERROR:dispatcher:w_ds_select_dst: no dst set
value

 

If I hardcode the value which in this case is 30 it works as expected.
I've verified that the correct value is in $var(dpattr) with an xlog
right before the call to ds_select_dst.

 

        if ($ruri.user =~ "[0-9]{4}") {

                xlog("L_NOTICE", "KAM_HOST: ($ci) $pr $mi route[$rm][0]
$fu -> $ru - Internal 4 digit call\n");

                if (dp_translate("2", "$ruri.user/$var(dpuser)")) {

                        xlog("L_NOTICE", "KAM_HOST: ($ci) -> DP
result='$var(dpuser)', attr='$var(dpattr)'\n");

                        setflag(FLAG_DIALPLAN);

                } else {

                        xlog("L_NOTICE", "KAM_HOST: ($ci) -> No matching
dialplan for $ru\n");

                }

       } some other if statements here with other pattern matches... 

 

        if (isflagset(FLAG_DIALPLAN)) {

                xlog("L_NOTICE", "KAM_HOST: ($ci) -> DP Attr is
$var(dpattr)\n");

                if (ds_select_dst("$var(dpattr)", "0")) {

                        xlog("L_NOTICE", "KAM_HOST: ($ci) $pr $mi
route[$rm][0] $fu -> DST='$avp(s:dispatcher-dst)', \

                                         GRP='$avp(s:dispatcher-grp)',
CNT='$avp(s:dispatcher-cnt)'\n");

                } else {

                        xlog("L_NOTICE", "KAM_HOST: ($ci) $pr $mi
route[$rm][0] $fu -> $ru - No dst gateways found\n");

                        sl_send_reply("404", "No destination gateways
found\n");

                }

        }

 

Thanks
