Yes, the default behavior without any flags is to use the GWs in the order they are defined in the DB. So if they are in the DB as
primaryGW,secondaryGW then the primaryGW will always be selected first, and secondaryGW will only be used if you perform failover in the script, with something like use_next_gw().

If you set it to 2 it will only ever use the first gateway and there will be no failover. If you want to allow for failover and use the gateways in the order they are defined you should not set any flags. https://opensips.org/docs/modules/2.4.x/drouting.html#idp163040<https://opensips.org/docs/modules/2.4.x/drouting.html#idp163040> Ben Newlin From: Users <[email protected]<mailto:[email protected]>> on behalf of David Villasmil <[email protected]<mailto:[email protected]>> Date: Wednesday, November 10, 2021 at 7:50 AM To: OpenSIPS users mailling list <[email protected]<mailto:[email protected]>> Subject: Re: [OpenSIPS-Users] drouting gw list Sorry, it's defined in cr_carriers, that's the list of gws which are then defined on dr_gateways. The "flags" field is "1", which i take to mean weight-based (this is opensips 2.4) So i would need to set the flags to "2"?

What is the value of the sort_alg column for that dr_rule/dr_carrier? If the sort_alg is set to W, then the assigned values are interpreted as weights. So with this configuration it would send 100 out of 110 calls to PrimaryGW and 10 out of 110 calls to SecondaryGW. If you don’t want to use the SecondaryGW except for failover you should not use weighted routing, so you should set the sort_alg column to N. https://www.opensips.org/Documentation/Install-DBSchema-3-2#GEN-DB-DR-RULES<https://www.opensips.org/Documentation/Install-DBSchema-3-2#GEN-DB-DR-RULES> Ben Newlin From: Users <[email protected]<mailto:[email protected]>> on behalf of David Villasmil <[email protected]<mailto:[email protected]>> Date: Tuesday, November 9, 2021 at 7:37 PM To: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> Subject: [OpenSIPS-Users] drouting gw list Hello folks, i have the following gw_list PrimaryGW=100,SecondaryGW=10 I'm seeing calls going to the SecondaryGW.
