1. Introduction
1.1. Background
With the introduction of the SIP protocol standard that supports telephony as well as a wide
range of other communication modes, there is a much broader range of SIP telephones available
to customers. This allows customers to replace their existing telephony infrastructure with
Avaya servers and re-use their existing telephones.
In addition, Avaya Communication Manager running on Avaya Media Servers and Gateways has
the capability to extend advanced telephony features to Outboard Proxy SIP stations. This
feature set can be extended to non-Avaya SIP phones, providing enhanced calling features in
advance of SIP protocol definitions and telephone implementations. See Section 3.1.
These Application Notes describe the configuration steps for using the Cisco 7940/7960 SIP
telephones with the Avaya Converged Communications Server, S8300 Media Server, and G700
Media Gateway. Only those configuration steps pertinent to interoperability of Cisco and Avaya
equipment are covered. General administration information can be found in the product
documentation as well as the specific references listed in Section 8. The configuration described
should be applicable to other Linux-based Avaya Media Servers and Media Gateways running
Avaya Communication Manager.
1.2. Configuration
The configuration used as an example in these Application Notes is shown in Figure 1. Several
Cisco 7940/7960 SIP telephones are configured in a single subnet with the Avaya Converged
Communications Server and S8300 Media Server with G700 Media Gateway. A PC provides
web browser and TFTP server support. The telephones are registered to the Converged
Communications Server and are also administered as Outboard Proxy SIP Stations in the S8300,
so that in addition to the SIP telephony features supported by the phones, Outboard Proxy SIP
features are available from Communication Manager. The media server also contains the Avaya
IA770 INTUITY™ AUDIX® Messaging Application for voice messaging support. These
Application Notes do not address configuration of the Avaya 4602 SIP telephones, which were
successfully tested using the standard product configuration steps.
The main difference between the Cisco 7940 and 7960 SIP telephones is the number of line
appearances supported by each phone (two and six, respectively). The configuration steps
described in these Application Notes apply to both models. Table 1 profiles the network
management capabilities of the phones.
