3. Supported SIP Features

In addition to standard calling capabilities (i.e., make a call, answer a call, drop a call), the

Internet Engineering Task Force (IETF) has defined a supplementary set of calling features,

often referred to as the SIPPING-19 [10]. This reference provides a useful framework to

describe product capabilities and compare features supported by various equipment vendors.

Table 3 provides a summary of SIP features supported on the Avaya 4600 Series IP Telephones

and Avaya one-X™ Desktop Edition when connected to the Asterisk Business Edition PBX.

Asterisk Business Edition PBX is a SIP registrar and acts as a "back-to-back user agent"

(B2BUA). The Asterisk server can be configured to support most of the SIP features. Based on

information from Reference [6], it is possible to configure the server to support some of the

remaining more advanced SIP features (e.g., single line extension, find-me). However, the

details in configuring these advanced SIP features are not readily available. For that reason,

these features are not tested. In Table 3, the features that were not tested due to lack of

configuration are identified in the Comments column.

Section 4, Section 5, and Section 6 of these Application Notes describe the steps for configuring

the Asterisk server and the Avaya clients to support the SIP features.

NOTE: The features that were tested for these Applications Notes are listed as “Yes” in the

“Supported” column in Table 3. “Yes” denotes that the feature is implemented by the Asterisk

server and by the Avaya phone device. “Yes” does not denote that the feature works. Features

that did not work are identified in the “Comments” column and in Section 7. “N/A” denotes

that this feature is implemented by the Asterisk server but is not implemented by the Avaya

phone device. “N/C” denotes that this feature is implemented by the Asterisk server but was not

configured for the test. “No” denotes that this feature is not implemented by the Asterisk server.
