Windows 10: VoIP application UDP port changes in the middle of the call causing audio cut-out

Hi All,


I have been dealing with a VoIP software in my computer running Windows 10 wherein my audio will cut-out while talking to someone from the said VoIP application.


I've checked the logs of the software and it appears there were multiple re-invite causing the counterpath softphone to change its port. Wireshark shows that the port was changed, but there is no indication what caused the application to send multiple re-invite, who/what other application used the port of my VoIP software.


Is there a tool that I can use to run in my Windows 10 machine to capture what triggers the application to change its port?


Thank you in advance!

:)

 

UDP Ports

Windows 10 appears to be a totally control-freak operating system and I'm hating it.

I'm trying to run a TeamSpeak 3 server on my computer. It uses UDP Port 9987. I can access the port locally, through localhost or 127.0.0.1, even my internal IP... 192.168.1.116. But the instant I try to access it from the internet, it fails to connect.
Yes, the port is forwarded in my router's port forwarding. Every program that uses TCP ports works just fine. But UDP ports are being blocked by something and I can't figure out what is blocking it. So, logically, since I don't have anything but the router,
windows firewall and windows defender, it MUST be windows. I've checked for proxies between the internet and my router and there are none. So, again, logically, the only option left is Windows 10 itself.

I use to be able to use UDP ports in Windows 7 and Windows 8. It stopped when I upgraded to 8.1 and then 10 it still doesn't work. Does anyone have any suggestiongs?

I have a local portforward checking application that pings a external server that then tries to connect using the specified protocol for the specified port and it works just fine on TCP 9987, but when I tell it to check UDP 9987, it immediately comes back
stating that a program is blocking the UDP 9987. Does anyone have any suggestions? Please, somebody help me get this working. I'm pulling my hair out here.

 

Data on UDP port 162 blocked

Hi,



Thank you for writing to Microsoft Community Forums.



We understand that you are trying to listen to traps on UDP port 162 and the application is not receiving any data.



Since you have already tried to create inbound rules to allow data on the UDP ports, and as you are still facing the same issue. In this situation, I would suggest you to post your query in

TechNet forums, where we have support professionals who are well equipped with the knowledge on this query to assist you with the appropriate details.

Data on UDP port 162 blocked

Hi

I am trying to listen to traps on UDP port 162, but the application is not receiving any data.

I can see the data onwireshark. I have created inbound rules to allow all data on UDP for all port numbers.

Looks like something else needs to be done to receive data.

I am using windows 10 Pro.

Thanks
