Chapter 3 Configuring Linksys ATAs Configuring a Streaming Audio Server Using a Streaming Audio Server The SAS feature lets you use attach an audio source to one of the Linksys ATA FXS ports (Phone 1 or Phone 2 on the PAP2T) and use it as a streaming audio source device. If the Linksys ATA has multiple FXS ports, either or both of the associated lines (Line 1 and Line 2 on the PAP2T) can be configured as an SAS server. To connect an external music source to an FXS port, use a media signal adapter, which provides a line in from a media source and a RJ-11 port for connecting to the FXS port on the Linksys ATA. The following is a URL for a device that has been tested with Linksys ATAs: http://www.neogadgets.com/cart/cart.php?target=product&product_id=17&substring=music+coupler After installing the music source using the media signal adapter and completing the required configuration on the Linksys ATA , when the line is called and the FXS port is off hook, the Linksys ATA answers the call automatically and streams audio to the caller. If the FXS port is on-hook when the incoming call arrives, the Linksys ATA replies with a SIP 503 response code (Service Not Available). The SAS line will not ring for incoming calls even if the attached equipment is on-hook. If an incoming call is auto-answered, but later the FXS port changes to on-hook, the SPA does not terminate the call but continues to stream silence packets to the caller. If an incoming call arrives when the SAS line has reached full capacity, the SPA replies with a SIP 486 response (Busy Here). The SAS line can be set up to refresh each streaming audio session periodically using a SIP re-INVITE message, which detects if the connection to the caller is down. If the caller does not respond to the refresh message, the SAS line terminates the call so that the streaming resource can be used for other callers. Each SAS server can maintain up to five simultaneous calls. If the second line on the Linksys ATA is disabled, then the SAS line can maintain up to 10 simultaneous calls. Further incoming calls will receive a busy signal (SIP 486 Response). If no calls are in session, battery is removed from tip-and-ring of the FXS port. Some audio source devices have an LED to indicate the battery status. This can be used as a visual indication as to whether audio streaming is in progress. Set up the Proxy and Subscriber Information for the SAS Line as you normally would with a regular user account. Call Forwarding, Call Screening, Call Blocking, DND, and Caller-ID Delivery features are not available on an SAS line. Using the IVR with an SAS Line The IVR can still be used on an SAS line, but the user needs to follow the following steps: Step 1 Step 2 Step 3 Step 4 Power off the Linksys ATA. Connect a phone to the port and make sure the phone is on-hook. Power on the Linksys ATA. Pick up handset and press * * * * to invoke IVR in the usual way.
