What is Strict RTP Learning?

Asterisk Asterisk SIP
1

My question is …

What is “Strict RTP learning…” as seen in console when a call is connected?

Is there a way to speed up the “RTP learning” process?

Can The “RTP Learning” parameters be specified instead of learned?

I need to reduce the connection delay on some devices that seem to have a 2 second connection delay after answer.

Strict RTP can be configured in rtp.conf and it is also stated what it does there[1].
