Remote SIP Phone on FreePBX Asterisk

Putting your IP address, and the ports that are opened, on a public forum is probably not a good idea.

Try this: Get away from software that has the word "Free" as part of it's name, and hire a consultant.

Thank you very much,however these ports are changes into my /etc/rtp.conf but anyway i keep your advice,

I have advice that i must set NAT on both router, has an better !!!

Thanks !

I discard this "Get away from software that has the word "Free" as part of it's name, and hire a consultant"

The IP he mentioned is non-routable private IP space inside his own network , as such, publishing it without a real world IP offers no security risk.

The router at the client end may or may not NAt the public IP to private space. So NAT may not be what you need to do.

However... the ports must be forwarded on the client router as well to the proper machine on the closed side of the router at the remote site and allow for outgoing traffic on the ports as well. I would allow both TCP and UDP packets to be passed.

Read the operator's manual or call the tech service people of the manufacturer.
