[Serusers] sequential hunting

[Steve Blair]

Hello:

 I would like to implement sequential hunting. Hunting is when a call 
arrives for a given subscriber, no one answers the original number so 
the proxy populates the username portion of the r-uri with another 
number (from the database) and tries again. This process continues until 
all numbers in the database are exhausted. I have the "failover" working 
but the r-uri field is not updated on any interation though the 
failure_route. Does anyone have any ideas how to make the following work?

Thanks,Steve

 # hunting (serial forking)
 if (avp_db_load("$ruri/username", "s:allow_hunt")) {
    if (avp_check("s:allow_hunt", "eq/y/i")) {
       avp_delete("s:allow_hunt");
       xlog("L_INFO", "\n[SER]: [%Tf] [%ci] Call Hunting Enabled for 
<%ru>\n");
       avp_db_load("$ruri/username", "s:huntlist/sam");
       xlog("L_INFO", "\n[SER]: [%Tf] [%ci] Call Hunting Started to 
<%ru>\n");
       t_on_failure("6");
       t_relay();
       break;
    };
 };

# Iterate through extension list for subscribers with call hunting enabled
failure_route[6] {
  xlog("L_INFO", "\n[SER]: [%Tf] [%ci] Failure Block #6: HUNTING for 
<%ru> from <%fu> at <%is>\n");
  if (avp_pushto("$ruri/username", "s:huntlist/g"))
  {
     append_branch();
     avp_delete("s:huntlist");
     t_on_failure("6");
     t_relay();
  };
}
