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
