3. Supported Calling Features

3.1. The SIPPING-19

In addition to basic calling capabilities, the Internet Engineering Task Force (IETF) has defined a supplementary set of calling features, often referred to as the SIPPING-19 [2]. This provides a useful framework to describe product capabilities and compare calling features supported by various equipment vendors. Table 3 gives a summary of calling features supported on the Cisco 7940/7960 SIP telephones within the Avaya SIP infrastructure. Some features require only the Converged Communications Server and Cisco telephones, while others additionally require Avaya Communication Manager and the Outboard Proxy SIP feature set.

Avaya Outboard Proxy SIP provides advanced calling features beyond the SIPPING-19 that can be extended to the telephone. These features are summarized in Table 4. Since the Cisco 7940/7960 SIP telephones are compatible with Outboard Proxy SIP, these features can be made available to the user. Details on their operation and administration can be found in Reference [4].

Section 4 of these Application Notes describes the steps for configuring the Cisco telephone and Avaya Converged Communications Server to support the basic feature set (those indicated by a “yes” in the Phone + Converged Communications Server column of Table 3). To take advantage of the extended feature set, including additional SIPPING-19 features (indicated in the Telephone + Converged Communications Server + Communication Manager/Outboard Proxy SIP column) and others listed in Table 4, the Cisco telephones must be configured for Outboard Proxy SIP support. The additional configuration steps required for this are described in Section 5.

The 7940 is a cost-effective option for teams that require essential communication features without the advanced capabilities of the 7960.

Both models support Power over Ethernet (PoE), allowing them to receive power and data through a single network cable. This technology simplifies installation and reduces clutter caused by excess cords. Moreover, both phones are designed to handle multiple lines, supporting features such as call hold, call transfer, and conference calling, which are essential for enhancing workplace productivity.

The Avaya 7960 and 7940 utilize the SIP (Session Initiation Protocol) standard, which ensures compatibility with a variety of VoIP systems and provides flexibility in deployment. They also incorporate high-quality audio technology, delivering clear voice quality during calls, which is critical for effective communication.

Security features in both models, including integrated encryption protocols, protect sensitive data from unauthorized access, making them a safe choice for organizations concerned about confidentiality. Additionally, their user-friendly interfaces and straightforward navigation menus make them accessible for employees of all technical levels.

In conclusion, the Avaya 7960 and 7940 phones are valuable assets for any business looking to enhance its communication infrastructure. With their range of features, support for modern technologies, and emphasis on usability, these phones serve as reliable tools for fostering efficient workplace interactions. Their combination of quality, functionality, and security makes them a preferred choice for many companies worldwide.
