31mua: no network

[ghost]

I've tried the taresip cocoa pod and it worked in the simulator but since it didn't work on a real device (arm64) I followed the guide here to compile the libraries myself but I think I might not have added them right to my project, now the code runs on the simulator but it writes this to the console right after starting.

[31mua: no network
error: stack

update: solved the no network error by adding guard baresip_init(conf_config(), 0) == 0 else { print("baresip init error"); return } to my code but now on the simulator it successfully establishes the call but I hear no audio, but when I run the same code on a real iPhone X it gives me a proxy error

code below: ` Import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.

}

override func viewWillAppear(_ animated: Bool) {
    var agent: OpaquePointer? = nil
    var client: SipClient? = nil
    do {
        client = try SipClient(agent: &agent)
    } catch {
        print("error: \(error) FDX")
    }
}

enum SipError: Error {
    case libre
    case config
    case stack
    case modules
    case userAgent
    case call
}

final class SipClient {

    required init?(agent: inout OpaquePointer?) throws {
        guard libre_init() == 0 else { throw SipError.libre }

        // Initialize dynamic modules.
        mod_init()
        print("after mod init")

        // Make configure file.

        if let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first {
            conf_path_set(path)
        }
        guard conf_configure() == 0 else { throw SipError.config}
        guard baresip_init(conf_config(), 0) == 0 else { print("baresip init error"); return }

        // Initialize the SIP stack.
        guard ua_init("baresip v" + BARESIP_VERSION  + " (" + ARCH + "/" + OS + ")", 1, 1, 1, 0) == 0 else { throw SipError.stack }

        // Load modules.
        guard conf_modules() == 0 else { throw SipError.modules }

        let addr = "sip:101@192.168.20.204:5060;transport=udp;answermode=auto;auth_pass=101;"

        // Start user agent.
        guard ua_alloc(&agent, addr) == 0 else { throw SipError.userAgent }

        // Make an outgoing call.

        guard ua_connect(agent, nil, nil, "sip:201@192.168.20.204:5060", VIDMODE_OFF) == 0 else { throw SipError.call }

        // Start the main loop.
        re_main(nil)
    }

    func close(agent: OpaquePointer) {
        mem_deref(UnsafeMutablePointer(agent))
        ua_close()
        mod_close()

        // Close and check for memory leaks.
        libre_close()
        tmr_debug()
        mem_debug()
    }  
}

} `
