Call Scenarios

 

 

 

 

 

Call Progress Tones

The ATA has configurable call progress tones. Call progress tones are generated locally on the ATA, so an end user is advised of status (such as ringback). Parameters for each type of tone (for instance a dial tone played back to an end user) may include:

•

•

•

number of frequency components

frequency and amplitude of each component

cadence information.

When one VoIP account is shared between the FXS and PSTN Lines, the following parameters are recommended to be set. See the Regional page in the “ATA Voice Field Reference,” on page121 for these and other call progress tone parameters.

Call Progress Tone

Description

 

 

VoIP PIN Tone

This tone is played to prompt a VoIP caller to enter a PIN number.

 

 

PSTN PIN Tone

This tone is played to prompt a PSTN caller to enter a PIN

 

number.

 

 

Outside Dial Tone

During two-stage PSTN-gateway dialing and with a dial plan

 

assigned, the ATA device collects digits from the VoIP caller and

 

processes the number using the dial plan. The ATA device plays

 

the Outside Dial Tone to prompt the VoIP caller to enter the

 

PSTN number. This tone should be specified to sound different

 

from the PSTN dial tone.

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.
