Rtp_symmetric = yes no longer works for vpn. Need to switch between yes and no

[Daft_Dutch]

Oke i have new regresion comming from debian to ubuntu.

Asterisk 18.10.0~dfsg+~cs6.10.40431411-2

My phone tcp connection worked locally. Over vpn and plane inet. (With firewall rulles)

Now i dont recieve speech to my phone when using vpn. This is my main outside connection so i switched to rtp_symmetric = no.

Anyone got a solution. I hoped i could set rtp_symmetric in the connection then i could create a seperate connection for the internet. But that is not working.

I don’t understand what you are trying to do, or the setup. I’d suggest taking a step back and explaining the network arrangement and showing SIP traces and logs.

Sure thing. Will post when im back at my local site.
Its quite easy

if im remote:
I can call with vpn off vpn does not bring back voice from remote phone.
With rtp_symmetric = yes

And if i set rtp_symmetric = no i can call with my vpn but normal internet gives troubles.
