Disconnect Tone

This value is the tone script which describes to the SPA the tone to detect as a disconnect tone. The syntax follows a standard Tone Script with some restrictions. Default value is standard US reorder (fast busy) tone, for 4 seconds.

Restrictions:

•2 frequency components must be given. If single frequency is desired, the same frequency is used for both

•The tone level value is not used. –30 (dBm) should be used for now.

•Only 1 segment set is allowed

•Total duration of the segment set is interpreted as the minimum duration of the tone to trigger detection

•6 segments of on/off time (seconds) can be specified. A 10% margin is used to validated cadence characteristics of the tone.

The Disconnect Tone Script and Impedance value for various countries follow:

US—480@-30,620@-30;4(.25/.25/1+2) —Impedance: 600

UK—400@-30,400@-30; 2(3/0/1+2) —Impedance: 370+620

France—440@-30,440@-30; 2(0.5/0.5/1+2) —Impedance: 270+750150nF

Germany—425@-10; 10(0.48/0.48/1) —

Impedance:220+820120nF

Netherlands—425@-30,425@-30; 2(0.5/0.5/1+2) —

Impedance: 600

Sweden—425@-10; 10(0.25/0.25/1) —Impedance:600 Norway—425@-10; 10(0.5/0.5/1) —Impedance: 600

Italy—425@-30,425@-30; 2(0.2/0.2/1+2)— Impedance: 220+820120nF

This makes it an ideal choice for businesses that want to retain their existing telephony infrastructure while transitioning to a VoIP system. The ability to utilize two telephone lines simultaneously provides flexibility and convenience, especially for users in a busy office environment.

The SPA2102 leverages Session Initiation Protocol (SIP) technology, which is widely recognized for its robustness and interoperability. The support for SIP ensures that the SPA2102 can work seamlessly with various VoIP service providers, offering users a broad range of options for their telecommunication needs. In addition to SIP, the device supports various codecs, including G.711, G.726, and G.729, allowing for flexible audio quality settings and bandwidth management.

Security is also a critical aspect of the SPA2102. It incorporates advanced encryption methods, such as Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS), to protect voice communications from potential eavesdropping. 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.
