Turning off call-hold - lose audio

[marc8lange]

Hello,

Extenson to extension calls work using outbound proxy siperb on both android and windows software siperb. When pressing the HOLD button in the app, the other party hears hold music. When pressing HOLD button again to turn off hold, hold music stops but now neither party can hear each other - total loss of audio.

PBX in use fusionpbx

Testing this same scenario using other endpoints like microsip or grandstream phones works as expected - hold on and off leads to nominal audio.

What is breaking on siperb?

Could you repeat the same test using the web version: https://www.siperb.com/phone/
We are currently on version 0.3 for the web and 0.4 for the mobile and desktop apps - there may be some issues in 0.4 still.

Actually, let me correct myself. I was actually conducting the test with web version (on windows machine) and android app when I experienced the failure...i was not using the windows app. Should I re-test with actual windows app?

Using the web version, open the Developer tools, and find the Network Tab. You will have to reload the page to see connections appear, then find the WebSocket connection to /ws/ and select it - when you select it, there should be a few tabs on the right, like Headers, etc. Look for Messages. These are the raw SIP messages - make your test calls, and check the SIP messages. You should either see the issue there, or send them to me, so i can check them out.
