register example - Request Timeout

[chumvan]

Hi,
I am trying to implement a simple Registra to store IP of the two SIP device, starting with the examples/register. However, the program failed to make SIP REGISTER and kept showing Request Timeout error as can be seen from the screenshot below:

Initially I ran the code in the mac M1 and then tried it again with the ubuntu 20.04 virtual machine. Neither of them worked.
I haven't edited the code yet, just cloning and running via go run ./exmples/register/main -c.

package main

import (
	"os"
	"os/signal"
	"syscall"
	"time"

	"github.com/cloudwebrtc/go-sip-ua/pkg/account"
	"github.com/cloudwebrtc/go-sip-ua/pkg/media/rtp"
	"github.com/cloudwebrtc/go-sip-ua/pkg/stack"
	"github.com/cloudwebrtc/go-sip-ua/pkg/ua"
	"github.com/cloudwebrtc/go-sip-ua/pkg/utils"
	"github.com/ghettovoice/gosip/log"
	"github.com/ghettovoice/gosip/sip/parser"
)

var (
	logger log.Logger
	udp    *rtp.RtpUDPStream
)

func init() {
	logger = utils.NewLogrusLogger(log.DebugLevel, "Register", nil)
}

func main() {

	stop := make(chan os.Signal, 1)
	signal.Notify(stop, syscall.SIGTERM, syscall.SIGINT)
	stack := stack.NewSipStack(&stack.SipStackConfig{
		UserAgent:  "Go Sip Client/example-register",
		Extensions: []string{"replaces", "outbound"},
		Dns:        "8.8.8.8"})

	if err := stack.Listen("udp", "0.0.0.0:5066"); err != nil {
		logger.Panic(err)
	}

	ua := ua.NewUserAgent(&ua.UserAgentConfig{
		SipStack: stack,
	})

	ua.RegisterStateHandler = func(state account.RegisterState) {
		logger.Infof("RegisterStateHandler: user => %s, state => %v, expires => %v, reason => %v", state.Account.AuthInfo.AuthUser, state.StatusCode, state.Expiration, state.Reason)
	}

	uri, err := parser.ParseUri("sip:[email protected]") // this acts as an identifier, not connection info
	if err != nil {
		logger.Error(err)
	}

	profile := account.NewProfile(uri.Clone(), "goSIP",
		&account.AuthInfo{
			AuthUser: "100",
			Password: "100",
			Realm:    "b2bua",
		},
		1800,
		stack,
	)

	recipient, err := parser.ParseSipUri("sip:[email protected];transport=udp") // this is the remote address
	if err != nil {
		logger.Error(err)
	}

	register, err := ua.SendRegister(profile, recipient, profile.Expires, nil)
	if err != nil {
		logger.Error(err)
	}

	time.Sleep(time.Second * 5)

	register.SendRegister(0)

	time.Sleep(time.Second * 5)

	register.SendRegister(300)

	time.Sleep(time.Second * 5)

	register.SendRegister(0)

	<-stop

	ua.Shutdown()
}

I saw some issues mentioned by @brnt but this seems to be a different one. Let me know if I could provide more info
Thank you for your help.

did you start any sip server?
For example go run examples/b2bua/main.go

Hi,
Yes, I tried that and was able to see the registration. Thank you!
Just to be sure, Is the port 5066 in this example assigned for the SIP client trying to register itself to the registra inside b2bua and how the function ua.SendRegister() is aware of address 0.0.0.0:5060 of the b2bua shown in my log ? I failed to track that.
Does this register demonstrate a separated example from the client/b2bua mentioned in the README.md i.e. Should the client work if I only run it and the examples/b2bua/main.go ? I will make a new issue if I should describe more details then.
