[SR-Users] Incoming DID calls routing to subscriber

Hello everybody, I'm trying to route incoming calls to kamailio with specific subscriber but I can't make it working. The complete scenario is: SoftSwith -> kamailio 5.3 -> zoiper What i'm trying to do is to receive a call into the zoiper when I dial specific DID which is already coming into the kamailio. It goes until the routing from kamilio to the subscriber account but it keeps in INVITE command, no response from the subscriber. Any help would be great! This is what I've been trying but no luck yet: if($rdir(name)=="downstream") {                  xlog("DID request was incoming call, called number: $rU  caller_id: $fU and source_ip $si \n");                 $sht(rtpProxy=>mip_$ci)=1;                 # We should take the called_number as username in table                 # Also validate if the number has active that DID, balance if needed, etc.                 # route(validate_customer);                 # I know, hardcoded for testing                 sql_xquery("ca", "select * from location where username = 1212 ", "ra");                 $avp(location_addr) = $xavp(ra=>received);                 xlog("DID did_incoming location is $xavp(ra=>received) \n");                 # Validate SIP OK                 #setflag(SIP_IP_OK);                 #$rU=$avp(dnis);                 #$rd=$avp(identity);                 #$rp=$avp(port); #               uac_replace_to($xavp(ra=>contact));                 uac_replace_to("sip:1212@voip.x.net:5060"); #               $ru = $var(duri);                 $ru=$xavp(ra=>contact);                 $ru="sip:1212@voip.x.net:5060";                 route(RELAY);         #       t_on_failure("dst_failure");         #       t_on_reply("dst_reply");                 if(!t_relay()) {                         sl_reply_error();                         exit;                 }                 exit;         } -- Regards, Jose N Figueroa
