SIP Over TLS

SPA2102, SPA3102, and WRP400 devices allow the use

 

of SIP over Transport Layer Security (TLS). SIP over TLS is

 

designed to eliminate the possibility of malicious activity

 

by encrypting the SIP messages of the service provider

 

and the end user. SIP over TLS relies on the widely-

 

deployed and standardized TLS protocol. SIP Over TLS

 

encrypts only the signaling messages and not the media.

 

A separate secure protocol such as Secure Real-Time

 

Transport Protocol (SRTP) can be used to encrypt voice

 

packets. SIP over TLS is configured in the SIP Transport

 

parameter configured in the Line tab(s). See “ATA Voice

 

Field Reference,” on page121.

 

 

Media Loopback

SPA2102, SPA3102, and PAP2T devices allow service

 

providers to use media loopback to quantitatively and

 

qualitatively measure the voice quality experienced by the

 

end user. One device acts as the audio transmitter and

 

receiver while the other device acts as the audio mirror.

 

The audio mirror transmits the audio packets that it

 

receives back to the transmitter/receiver instead of

 

transmitting the data sampled on its local microphone (IP

 

phone) or attached analog telephone (ATA-type device).

 

Media loopback is configured in the User tab. 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.
