The user network firewall only allows the IP address of PBX to be outward. How to set up extensions to forward through PBX instead of point-to-point ？

Is it possible to activate the always use DSP option in the routing parameters?

Hi,

What is the issue you are having? If the phones use direct media then they shouldn't need to traverse the firewall if they are on the same lan.

Always use DSP is generally the way to stop direct media.

The information for call establishment is from internal terminal to PBX to external terminal，after the call is established, the IP packet is directly transmitted between the IP addresses of the two terminals. My issue is how to setting to keep terminal(internal)---pbx-----terminal(external) status in whole call progress。
