Hello Daniel;

here cfg and results . i tested all of them one by one . i added some log to understand what is log. Extra note; t_relay_to_avp is not documented and fixup function cannot fix_param because it find FPARAM_STR.

Thanks

$avp(pp)="5061";

$avp(add)="192.168.1.17";

$avp(addr)="192.168.1.17:5061";

$avp(dd)="udp:192.168.1.17:5061";

$avp(flags)="0x04";

#xlog("L_INF0","$C(xy) [SIPP] [extra_id_pv : $avp(reng_extraid) ] [setid_avp : $avp(setid) ] [rtp_inst_pvar : $avp(rtp_instance) ] $C(xx) \n");

if(t_relay_to_udp("$avp(add)", "$avp(pp)")){

xlog("L_ERR","Relay Problem UDP \n");

sl_send_reply("503","Relay Problemed");

exit;

}

if(t_relay_to( "$avp(dd)","$avp(flags)")){

xlog("L_ERR","Relay Problem UDP \n");

sl_send_reply("503","Relay Problemed");

exit;

}

if(t_relay_to_avp( "$avp(pp)","$avp(add)")){

xlog("L_ERR","Relay Problem UDP \n");

sl_send_reply("503","Relay Problemed");

exit;

}

if(t_relay( "$avp(add)","$avp(pp)")){

xlog("L_ERR","Relay Problem UDP \n");

sl_send_reply("503","Relay Problemed");

exit;

}

Subject: [SR-Users] passing $avp to t_relay functions.

Hello ,

is there a way to pass $avp values to t_relay function. i tried ;

t_relay

t_relay_udp/tcp

t_relay_to

t_relay_avp functions

log

0(75155) ERROR: tm [tm.c:2456]: fixup_t_relay_to(): fixing ($avp(dd), 1)

in addition i have a look code , in fixup functions try to resolve host values so parameteres cannot find $avp .

in conclusion , does kamailio need new function to pass $avp value? Can i try to code?

Thanks.
