Making an outgoing call is as easy as from a normal telephone. Call progress tones like Dial Tone, Ring Back Tone and Busy Tone are fed to the caller as per the called number status. The FXS ports can make outgoing calls on a common or nine different SIP accounts. In addition, number based SIP account selection is provided to select the most economical SIP account for a given outgoing number.

An incoming call from a SIP account can be routed to any one of the FXS ports. All different CLIP protocols are supported so that the user can identify the caller before answering the call.

Once a call is established from SIP FXS Gateway, features like Call Hold, Call Transfer and Call Forward are supported to manage two calls from the same FXS port. Call Forward in different conditions and Do Not Disturb are also provided.

The FXO (PSTN Pass-Through) port allows the user on the first FXS port to selectively dial certain numbers on the PSTN. This line can be used to make emergency or normal calls or when Internet connectivity is not required or unavailable.
