Opensips cannot connect to PSTN

Question

I have recently installed Opensips 3.1. I am able to add SIP phones and place local LAN calls. I am trying to setup a inbound gateway connection with SIP provider Skyetel using IP Authentication. Everything is setup on the Skyetel side. From Opensips Control Panel, routing has been setup with all of the Skyetel gateways. Skyetel sends OPTIONS request, but Opensips seems not be able to process the request. Opensips is sending a 403 Relay Forbidden response. I am using the default config file, and I see that the 403 response is processing at the below step -

if ( !(is_method("REGISTER")  || is_from_gw() ) ) {

                if (is_from_local()) {
                        # authenticate if from local subscriber
                        # authenticate all initial non-REGISTER request that pretend to be
                        # generated by local subscriber (domain from FROM URI is local)
                        if (!proxy_authorize("", "subscriber")) {
                                proxy_challenge("", "auth");
                                exit;
                        }
                        if ($au!=$fU) {
                                send_reply(403,"Forbidden auth ID");
                                exit;
                        }

                        consume_credentials();
                        # caller authenticated

                } else {
                        # if caller is not local, then called number must be local

                        if (!is_uri_host_local()) {
                                send_reply(403,"Relay Forbidden");
                                exit;

Also, I have added the SKyetel gateways as aliases in the config file and no change.


alias="52.41.52.34"
alias="35.85.225.96"
alias="52.60.138.31"
alias= 3.99.65.224
alias="52.8.201.128"


Any help on this would be appreciated.
