Encrypted Channels being captured and sent to Calls and RDIO #900

Closed buccipgh closed 8 months ago

buccipgh commented 8 months ago

I recently upgraded to 4.7.1 and now it is sending small blips of audio clips to Calls and RDIO. I placed a minDuration of 1.5 and it seems to have stopped it from happening... But this was new... Here is a quick log grab of an Encrypted TG. Shows it is Encrypted but it goes thru everything till it gets to the 1.5 sec timeout. If that 1.5 min was not in there it was sending it to Calls and RDIO.

Thanks.

Short answer: if you set newCallFromUpdate: false in your config.json, it should behave like before.

You probably have some reception issues with your control channel. When you see Call was UPDATE not GRANT, it means that trunk-recorder did not capture the original call grant that was sent. In 4.7.1 calls can be started by a grant update, but the updates lack some of the important metadata about the call such as whether or not it is encrypted. It can than take a second for the voice recorder to receive and process the encryption information that is being sent on the voice channel.

Thank you!
I have just made the change and it already seems better. Thanks again!
