Re: RTP address learning and timing problem

It's probably best if you read the logic[1]. There's an entire comment that talks about how it works.

Hi Joshua,

Could you confirm if the 5 second period for learning a new audio stream is a minimum or a maximum? The unusual call flow in question results in Asterisk learning a new audio stream when we don't want it to, and having a minimum of say 2 seconds of audio would help avoid this.

Thank you!

Hello,

Does anyone know if one of the "strictrtp" options disables RTP learning? As far as I can tell from the documentation the values "no" and "seqno" are more permissive in allowing other sources rather than less, but I thought I'd check.

Setting it to "no" disables the learning.

Since I haven't gotten the email yet I'll just reply to my own.

The "no" option disables strict RTP protection. Learning is part of strict RTP protection, it is what determines what the source of media is and then blocks other packets. There is no ability to set it per-peer/per-endpoint.
