Telephone ports

The Internet Gate has local telephone ports (FXS) allowing connection of analogue telephones, and telephone line port (FXO) allowing connection to a telephone landline.

Telephones connected to the PH ports can be used as SIP phones.

You either control phone behaviour using the Telephone ports page or dial codes.

The LINE port can be attached to an ordinary telephone line. Then phones connected to the PH ports as well as all SIP phones on LAN can use that telephone line to dial out.

If anyone calls the telephone number of the phone line connected to the LINE port, the call will by default be forwarded to the telephone connected to the PH1 port.

This behavior can be changed on the Telephone Port page.

You can also set up more advanced functions, like collection of extension digits and directly allow forwarding of incoming calls to certain SIP clients. This works if you have given your SIP clients numeric SIP user names, or if you use the extension number feature of the optional SIP Switch software.
