Hi,
Via headers and record route are not "extra" but mandatory, you cannot remove them otherwise you will brake the call flow.

In order to decrease the size you can remove codecs from the sdp.
You can add the codecs whitelist/blacklist in your config.yml.

Is it possible for you to remove some of the extra Via header or Record route in your signaling. Typically packets don't have the extra routes and Vias for your private IP addresses. If you can cut down the packet size I believe that calls should be getting connected as expected. Let me know if that helps."
