Other parameters may need to be changed from the defaults, depending on the requirements of a specific ITSP. Some of the commonly configured parameters include the following:

•Streaming Audio Server—You can enable an external music source for music on hold. See the “Configuring a Streaming Audio Server,” on page 90 for further information.

•NAT Settings—You can adjust these settings to resolve issues that arise when using a ATA on a network behind a Network Address Translation (NAT) device. See the “Network Address Translation (NAT) and Voice over IP (VoIP),” on page 47 for further information.

•Subscriber Information—You can configure security parameters. See the “Secure Call Implementation,” on page 72 for further information.

•Dial Plan—You can configure a dial plan for a specific line. See the “Configuring Dial Plans,” on page 61 for further information.

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.

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.
