[asterisk-users] RTP address learning and timing problem

[David Cunningham]

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!
