[Bug]: Linphone Freezes when answering a call #690

Open flaviogoncalves opened 2 years ago

flaviogoncalves commented 2 years ago

Context

I'm evaluating Linphone as a softphone for our company

General information

Expected behaviour

I wanted to receive a call using the PCMU codec, but linphone desktop freezes (not reponsive for SIP library). I have to go to Task Manager to stop the software and try again. It is able to make calls to other phones.

To Reproduce

  1. Make a call from any other from linphone Android to Linphone destop. Linphone Android is working just fine.

Additional context

No response

Hi First, avoid using UDP : https://wiki.linphone.org/xwiki/wiki/public/view/Linphone/Good%20practices%20for%20using%20SIP/

Second, do you receive the receiving call notification? If not, check with your OS/Antivirus if they don't block the application.

Thanks for the answer. I have changed to TLS, but I had the same problem. I've removed silence suppresions, same problem. I've removed the header Allow-Events, same problem. It seems to me that it is an OS stuff. The program simply freezes after receiving the call. It is able to send a call normally. I've tried also disabling the windows defender firewall, no luck too. Maybe a way to remove completely linphone and reinstall from scratch. I'm getting out of new ideas on how to solve it. My next step is to use a simple asterisk with linphone.

I don't think it is related to SIP or servers. Your logs show that a call notification has been created and there are no errors about it. If the application freeze then I guess it is stuck when showing this popup notification. and then, it is mostly related to a GUI behavior (OS, third party or drivers that block it). Maybe your system prevent creating multiple windows with no decoration, I don't know. But my best shot is to try to answer at "why don't you see this popup?" .

I can see the popup, but frozen.

I've discovered. Two screens, the popup was popping up in the second screen. I've removed the second screen and it worked. May eventually be related to the LG hdmi audio driver. After removing the second screen the call is going thru.
