ATA Software Features

 

 

 

 

 

Feature

Description

 

 

Calling Party

Calling Party Control (CPC) signals to the called party

Control

equipment that the calling party has hung up during a

 

connected call by removing the voltage between the tip

 

and ring momentarily. This feature is useful for auto-

 

answer equipment, which then knows when to disengage.

 

CPC is configured in the Regional, Line, and PSTN Line

 

tabs. See “ATA Voice Field Reference,” on page121.

 

 

Report Generation

The ATA device reports a variety of status and error

and Event Logging

reports to assist service providers to diagnose problems

 

and evaluate the performance of their services. The

 

information can be queried by an authorized agent, using

 

HTTP with digested authentication, for instance. The

 

information may be organized as an XML page or HTML

 

page. Report Generation and Event Logging are

 

configured in the System, Line, and PSTN Line tabs. See

 

“ATA Voice Field Reference,” on page121.

 

 

Syslog and Debug

Syslog and Debug Sever Records log more details than

Server Records

Report Generation and Event Logging. Using the

 

configuration parameters, the ATA device allows you to

 

select which type of activity/events should be logged.

 

Syslog and Debug Server allow the information captured

 

to be sent to a Syslog Server. Syslog and Debug Server

 

Records are configured in the System, Line, and PSTN

 

Line tabs. See “ATA Voice Field Reference,” on page121.

 

 

SIP Over TCP

To guarantee state-oriented communications, SPA2102

 

and SPA3102 devices allow you to choose TCP as the

 

transport protocol for SIP. This protocol is “guaranteed

 

delivery”, which assures that lost packets are

 

retransmitted. TCP also guarantees that the SIP packages

 

are received in the same order that they were sent. As a

 

result, TCP overcomes the main disadvantages of UDP. In

 

addition, for security reasons, most corporate firewalls

 

block UDP ports. With TCP, new ports do not need to be

 

opened or packets dropped, because TCP is already in

 

use for basic activities such as Internet browsing or e-

 

commerce. SIP over TCP is configured in the Line tabs.

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.
