Can I connect Zoiper to GOIP? - call

I used GOIP to send SMS from my application. Sometime, client call to this phone number but they cannot connect because I didn't config Income Call on GOIP.
Is it possible to connect Zoiper application (Android) to GOIP without Call Center Gateway?

No you can't! GOIP is an UAC as Zoiper as UAC too.

Can't connect to my React app from my mobile device

I am having some issues connecting to my React app running on my PC from my mobile device. I remember being able to do it awhile back, but for some reason it's not working anymore.
Both devices are on the same WiFi network. I have mesh routers and I verified they are connected to the same one (not sure if that matters). I'm running Windows 11 and trying to connect from an Android device.
I'm getting a connection timeout when trying to connect to my app from my phone (ip address below is fake):
This site can't be reached
192.559.2.27 took too long to respond
Try:
Checking the connection
ERR_CONNECTION_TIMED_OUT
I verified that the ip address I'm trying to connect to is the correct one and I am attempting to connect to the right port. Any thoughts on what the issue might be or some settings I could check?
The answer here was to simply set my home WiFi network as a private network. Windows 11 sets the network type to "public" by default, which prevents it from being discovered by other devices on the network.
On Windows 11, go to Settings -> Network & Internet -> Wi-Fi -> properties
Change the Network profile type to private
Obviously, you'll only want to do this on a trusted network and not a public Wi-Fi or anything.

aws_sdk: how can I identify if my device is connected to the aws server

I have a device (esp32s2) which is IoT enabled and communicating with AWS server.
The device is connecting to the internet via router. I want to check from the device, if the router is connected to the internet or not. If not connected, I need to disconnect mqtt broker instantly.
I know there is aws_iot_yield happening, but it is taking too much of time to change the client state (~5-10 mins) after disconnection. So, is there is any other way in which I can come to know if the device is connected to the mqtt broker or not using AWS sdk?
I want to avoid using pinging to some address/server as it will increase the usage of resources.
Thanks in advance!
Since the connectivity to the AWS server trough internet depends on the network elements, the only reliable way to know if you are connected to internet is to send a package to a know address and receive the response. Simplest way to do this is to use ICMP (ping) protocol. Usually the most reliable destination to ping is the Google DNS server 8.8.8.8 or 8.8.4.4 which is a cluster service and it's always replying on the ping.
You can control the pause between two pings and how many pings you will send in one session in order to preserve the resources.
Alternative approach is to use a router that can send messages to a monitoring device that the link state was changed (by example SNMP trap). But this is not fully reliable method since the router can not detect all scenarios where the connectivity to your AWS server is lost.

ionic chat application using socket.io(how to make my user to join chat.socket.io)

I am trying to do chat application using socket.io.
i have refereed this tutorila
https://www.sitepoint.com/using-socket-io-and-cordova-to-create-a-real-time-chat-app/
i am not able to get connected to the common server look here http://chat.socket.io/
i would like to create an app where all the user enter the name and connect the chat.socket.io group. what is the server host they are using how can i connect my app users to join the chat.socket.io.
problem is i am not able to connect my users to http://chat.socket.io/
UPDATE:
Lets say an example:
In my app i am having number of users and i have button called chat
when the user clicked the chat button he should enter this page http://chat.socket.io/ and i need a exit button to exit the chat
To connect with server we need some thing like this "http://54.200.176.147:8888/socket.io/socket.io.js" is there any
port available for chat.socket.io please let me know
I would rather suggest you to setup your own server than trying to connect to http://chat.socket.io You can setup your own server using nodejs and express and listen & broadcast chat messages.
Suggest you to check out this socket io chat link for setting up the server and trying out basic chat. You can also download the server setup from my github page and follow the chat link instruction to run the same which listens on port 3000. Hope it helps

DNN 7 - SMTP Test in host settings work, but can't send emails in contact forms

All the sites on this DNN installation stopped sending emails yesterday. When you try and test SMTP in host settings, it sends the test email without any issues.
At first I thought my IP might be blacklisted, but then surely the SMTP test would also fail?
I'm pretty sure the Test SMTP setting in Host directly calls the send mail service in DNN's API. But many other emails are queued up for dispatch for scalability.
Check to see if your "Messaging Dispatch" job in Host > Scheduler has been disabled. If not, check the history by clicking the Log icon on the right-hand side of the schedule tasks list. See if there are errors logged in there.
If all is good there, check your Logs in /Portals/_default/Logs for any issues related to messaging or SMTP.
I would start by checking to see if you have defined a valid (usable) email address on your ADMIN account. DNN will "send" emails from whatever the Administrator is in the site settings, so check the email address on that user's profile, make sure that the email/domain is valid and the SMTP settings you are using are allowed to send from that domain.
If you are developed contact-form dynamic module in your DesktopModules folder then you have to call below DNN SendMail method in your submit button click event.
DotNetNuke.Services.Mail.Mail.SendMail(FromEmailAddress, ToEmailAddress, CCEmailAddress, BCCEmailAddress,
DotNetNuke.Services.Mail.MailPriority.Normal,
EmailSubject,
DotNetNuke.Services.Mail.MailFormat.Html,
System.Text.Encoding.UTF8,
EmailBodyMessage, "", "", "", "", "");

EndpointNotFoundException on client machine

My WCF Service is hosted under net.tcpbinding and in case it is not running when client makes a call to its methods but let me tell you our some of clients get access and some of not. i even check antivirus setting and firewall setting for each client but haven't came up with right answer , client gets the EndpointNotFoundException with this message:
There was no endpoint listening...
i have check the path of service there is no mistake in path. and in my nettcp service based on window credential type and enabletcpportsharing is also on.
Still searching for right solution.
Thank you!
After trying telnet (IP Address of app server) Port. so i can understand it's blocking by window firewall or router firewall. if telnet open window from client machine that's mean its working and if not opening in window then call Network administrator to open that port
Eg. telnet xxx.xx.xx.xx 80 in command prompt
