If you plan on using phones or accessing your Digium Switchvox PBX from remote locations such as home or a hotel, your network administrator must forward certain ports back to your PBX. (There are other ways to reach your server as well, such as VPN tunnels and SIP gateways, but we’ll concentrate on Port Forwarding for this article.) That way you can reach your Switchboard panel or use the Switchvox moblie applications with ease. You can do this by entering either the Public IP address of your Switchvox server (Such as**http://18.104.22.1689/**) or if your network admin has set it up correctly, a fully qualified domain name (Such as http://pbx.yourcompany.com/). Please see your network administrator for your Switchvox address.
The following is a list of ports that are used by the PBX. Depending on your requirements, you can forward just the ports needed by phone, just the web access ports, or all of them.
|**Used by Remote Phones**|
|UDP||5060||SIP signaling port needed for phones outside your network|
|UDP||10000-20000||RTP audio ports needed for phones outside your network|
|**Used for accessing the PBX web interface remotely**|
|TCP||80||HTTP port for remote web voicemail access|
|TCP||443||HTTPS port for remote web admin access|
|TCP||5222 & 843||**SMB Systems Only** – ports for using the Switchboard remotely|
|TCP||5269||**SMB Systems Only **– port for remote XMPP (Jabber/chat) access ([Extensible Messaging and Presence Protocol](http://en.wikipedia.org/wiki/Extensible_Messaging_and_Presence_Protocol "http://en.wikipedia.org/wiki/Extensible_Messaging_and_Presence_Protocol"))|
|**Used by Tech Support Access**|
|UDP||1194||Must be open to outgoing traffic|
