[OpenSIPS-Users] DROUTING module changing Carrier IDs

[Newlin, Ben]

I am using OpenSIPS 1.11 and I am recently getting some weird behavior from the DROUTING module. The module is corrupting the Carrier ID that is being returned via AVP. This behavior is occurring only with the Carrier ID, not the gateway or rule IDs, and only when it is returned from the DROUTING module via dr_is_gw() or do_routing(). If I query the database directly using AVPOPS, the Carrier ID is returned correctly.

I have the following configuration. The startup_route was added specifically for this issue.

####  Dynamic ROUTING module
loadmodule "drouting.so"
modparam("drouting", "db_url", "CFG_DB_URL")
modparam("drouting", "persistent_state", DISABLE)
modparam("drouting", "probing_interval", ENABLE)
modparam("drouting", "force_dns", ENABLE)

modparam("drouting", "ruri_avp", '$avp(dr_ruri)')
modparam("drouting", "gw_id_avp", '$avp(dr_gw_id)')
modparam("drouting", "gw_priprefix_avp", '$avp(dr_gw_prfx)')
modparam("drouting", "rule_id_avp", '$avp(dr_rule_id)')
modparam("drouting", "rule_prefix_avp", '$avp(dr_rule_prfx)')
modparam("drouting", "carrier_id_avp", '$avp(dr_carr_id)')
.
.
.
startup_route {
  avp_db_query("select carrierid from dr_carriers", "$avp(ids)");
  for ($var(id) in $(avp(ids)[*]))
    xlog("L_INFO", "Carrier ID: $var(id)\n");
}
.
.
.
route[get_route]
{
  if (!do_routing("$avp(dr_group)", "", , "$var(rule_attr)", "$var(gw_attr)", "$var(carr_attr)"))
  {
    xlog("L_ERR", "get_route: failure from do_routing! $retcode\n");
    route(reply_error, "500", "Server Internal Error");
  }

  xlog("L_INFO", "get_route: rule_attr - $var(rule_attr)\n");
  xlog("L_INFO", "get_route: gw_attr   - $var(gw_attr)\n");
  xlog("L_INFO", "get_route: carr_attr - $var(carr_attr)\n");

  xlog("L_INFO", "get_route: ruri      - $avp(dr_ruri)\n");
  xlog("L_INFO", "get_route: gw_id     - $avp(dr_gw_id)\n");
  xlog("L_INFO", "get_route: gw_prfx   - $avp(dr_gw_prfx)\n");
  xlog("L_INFO", "get_route: rule_id   - $avp(dr_rule_id)\n");
  xlog("L_INFO", "get_route: rule_prfx - $avp(dr_rule_prfx)\n");
  xlog("L_INFO", "get_route: carr_id   - $avp(dr_carr_id)\n\n");
}

The output from the above execution is:

opensips[9801]: Carrier ID: IndyEdges
opensips[9801]: Carrier ID: Level3-VT
opensips: INFO:core:daemonize: pre-daemon process exiting with 0
opensips[9801]: get_route: rule_attr -
opensips[9801]: get_route: gw_attr   -
opensips[9801]: get_route: carr_attr - id=pai;history=hi
opensips[9801]: get_route: ruri      - <null>
opensips[9801]: get_route: gw_id     - Level3-VT1
opensips[9801]: get_route: gw_prfx   - +
opensips[9801]: get_route: rule_id   - 4
opensips[9801]: get_route: rule_prfx - 1
opensips[9801]: get_route: carr_id   - Level3-VT#012

You can see that the string '#012' has been appended to the Carrier ID. So far it has always been that string appended to the ID.

It started occurring after I moved from a RHEL 7 server using MariaDB to a RHEL 6 server using MySQL, but in both cases I am using the provided OpenSIPS scripts to create all database tables.

Any help would be appreciated.
