Not able to register using PJSIP ios library

[Anuran Barman <anuranbarman@xxxxxxxxx>]

I am trying to register my sip account to my Kamailio SIP server using https://github.com/chebur/pjsip which is using pjsip 2.7.1. 

I am getting SIP registration error: No suitable credential (PJSIP_ENOCREDENTIAL) [status=171101] 

From the Doc it says it happens when you are not giving proper realm and scheme while registering. But the thing is it successfully registers itself when using given ios example app from pjsip library where you do telnet connection and execute pjsip-cli command. So that means '*' as realm and 'digest' as scehem is working but it does not when I am using this library.

My code is like below, what should I do?

        var status = pj_status_t()
       
        pjsua_create()
       
        var ua_cfg:pjsua_config = pjsua_config()
        var log_cfg:pjsua_logging_config = pjsua_logging_config()
        var media_cfg:pjsua_media_config = pjsua_media_config()
       
        pjsua_config_default(&ua_cfg);
       
        pjsua_logging_config_default(&log_cfg);
        pjsua_media_config_default(&media_cfg);
       
        pjsua_init(&ua_cfg, &log_cfg, &media_cfg);
       
        var transportConfig:pjsua_transport_config = pjsua_transport_config()
       
        pjsua_transport_config_default(&transportConfig);
       
        transportConfig.port = 5060;
       
       
       
        pjsua_transport_create(PJSIP_TRANSPORT_UDP, &transportConfig, nil);
       
       
        status = pjsua_start();
       
       
        var acc_cfg = pjsua_acc_config()
       
       
        pjsua_acc_config_default(&acc_cfg);
       
        acc_cfg.id = giveStruct(string: "sip:1001@105.156.199.132")
        acc_cfg.reg_uri = giveStruct(string: "sip:105.156.199.132:5060")
        acc_cfg.cred_count = 1;
        acc_cfg.cred_info.0.realm = giveStruct(string: "*")
        acc_cfg.cred_info.0.scheme = giveStruct(string: "digest")
        acc_cfg.cred_info.0.username = giveStruct(string: "1001")
        acc_cfg.cred_info.0.data_type = 0
        acc_cfg.cred_info.0.data = "" "1001")
        acc_cfg.reg_timeout = 3600
        acc_cfg.register_on_acc_add = 1
        acc_cfg.allow_contact_rewrite = 1
        pjsua_acc_add(&acc_cfg,1, &accountId)
