Hi Experts,
We have a new remote site and we are going to configure new phone VLANs.
I would like to know what are the ports to allow from our firewall on both the remote site and the main office.
The voice gateway is in the main office. I saw below link and was able to identify for the phones, but I am confused regarding the gateway ports since the voice gateway will be in the main office. I am concerned on the ports when the media already connects, or should I just follow what is everything on this link regardless if where the voice gateway located?

Does someone have a already list of firewall ports to allow in this kind of scenario? Can you please share? Thanks!
