Configuring a Streaming Audio Server

 

 

 

 

 

After you complete the required configuration, the FXS port is ready to stream audio. The functionality depends on the hook state of the FXS port:

•If the FXS port is off hook, an incoming call is answered automatically and audio is streamed to the calling party.

NOTE Each SAS server can maintain up to five simultaneous calls. If the second line on the unit is disabled, then the SAS line can maintain up to 10 simultaneous calls. Further incoming calls receive a busy signal (SIP 486 Response).

•If the FXS port is on-hook when the incoming call arrives, a SIP 503 response code is transmitted to indicate “Service Not Available.”

•If an incoming call is auto-answered, but later the FXS port changes to on-hook, the call is not terminated but continues to stream silence packets to the caller.

•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.

Additional information:

•The SAS line does not ring for incoming calls even if the attached equipment is on-hook.

•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.

•Call Forwarding, Call Screening, Call Blocking, DND, and Caller-ID Delivery features are not available on an SAS line.

This focus on security makes the SPA2102 a reliable choice for businesses concerned about the confidentiality of their conversations.

The device is easy to configure and manage, thanks to its web-based interface. This allows administrators to quickly set up the adapter, manage network settings, and troubleshoot any issues that may arise. Furthermore, the SPA2102 supports Quality of Service (QoS) features, ensuring that voice traffic is prioritized over other types of network traffic, which enhances call quality and reliability.

Overall, the Cisco SPA2102 is a powerful, user-friendly VoIP adapter that combines traditional telephony with modern IP technology. Its dual-port capability, support for SIP, extensive security features, and ease of configuration make it a solid choice for businesses looking to innovate their communication systems while minimizing disruption.
