Description

 

 

Signaling Hook

The ATA device can signal hook flash events to the remote

Flash Event

party on a connected call. This feature can be used to

 

provide advanced mid-call services with third-party-call-

 

control. Depending on the features that the service

 

provider offers using third-party-call-control, the following

 

ATA features may be disabled to correctly signal a hook-

 

flash event to the softswitch:

 

• Call Waiting Service (parameter call waiting serv set in the

 

Line tab)

 

• Three Way Conference Service (parameter three-way conf

 

serv set in the Line tab)

 

• Three Way Call Service (parameter three-way call serv set

 

in the Line tab)

 

You can configure the length of time allowed for detection

 

of a hook flash using the Hook Flash Timer parameter on

 

the Regional tab of the administration web server. See

 

“ATA Voice Field Reference,” on page121.

 

 

Configurable Dial

The ATA device has three configurable interdigit timers:

Plan with Interdigit

Initial timeout (T)—Signals that the handset is off the hook

Timers

and that no digit has been pressed yet.

 

 

Long timeout (L)—Signals the end of a dial string; that is,

 

no more digits are expected.

 

Short timeout (S)—Used between digits; that is after a

 

digit is pressed a short timeout prevents the digit from

 

being recognized a second time.

 

See “Configuring Dial Plans,” on page 61 for more

 

information.

 

 

Polarity Control

The ATA device allows the polarity to be set when a call is

 

connected and when a call is disconnected. This feature is

 

required to support some pay phone system and

 

answering machines. Polarity Control is configured in the

 

Line and PSTN Line tabs. See “ATA Voice Field Reference,”

 

on page121.

The Cisco Systems SPA2102 is a versatile Voice over Internet Protocol (VoIP) adapter that serves as a bridge between traditional telephony systems and modern IP networks. Designed primarily for small to medium businesses, the SPA2102 is highly regarded for its reliability, ease of use, and rich feature set. This device allows users to make and receive phone calls over the internet while maintaining the ability to connect traditional analog phones.

One of the standout features of the SPA2102 is its dual-port capability. The device includes two FXS ports, allowing users to connect two separate analog telephones. 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. Whether used in a small office or a larger organizational setting, the SPA2102 continues to be a reliable component of VoIP solutions.
