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 te

3.2. Message Waiting Indicator (MWI) With the Outboard Proxy SIP extended feature set, a SIP telephone that supports IETF RFC 3265 and MWI Draft 4 (Subscribe/Notify method) will illuminate/extinguish its MWI lamp when voice messages are left/read for that extension. Since the Cisco 7940/7960 SIP phones support only the unsolicited Notify method for MWI, this feature is not currently supported in Communication Manager. 4.

4.2. Configure the Cisco 7940/7960 SIP Telephone Cisco 7940/7960 SIP telephones can be configured using two methods: 1. Configuration files downloaded from a TFTP server specified via DHCP at boot time. Two such files are installed on the TFTP server: a default configuration file containing parameter settings that apply to all phones (SIPDefault.cnf), and a phone-specific configuration file containing settings applicable only to that phone (SIP.cnf, where is t

Steps Description 1. Edit the default and phone-specific configuration file(s). The table below shows the relationship between the parameters that must be configured for the phone and those administered in the Converged Communications Server for a telephony user. A sample value is shown for the configuration in Figure 1. Parameter names have the form ObjectNameXParamName, where “X” refers to the line appearance number to which the parameter applies (1-2 for the 7940 and 1-6 for the 79

Steps Description 2. Reboot the phone. If TFTP support has been properly configured, the phone will download the default and specific configuration files, and register with the Avaya Converged Communications Server. Registration can be verified by the absence of an “X” near the phone icon for the line appearance, as shown below. Registered Unregistered For basic feature set operation, the dial plan can be specified using: 1. Address maps in the Avaya Converged Communications Ser

5. Configuring for the Extended Feature Set In addition to the steps outlined in Section 4, the following additional administration steps are required to support the extended feature set on the Cisco 7940/7960 SIP telephones: 1. On Communication Manager, define stations corresponding to those specified on the Avaya Converged Communications Server, off-PBX station mappings to route call requests involving those stations to the Avaya Converged Communications Server, and off-PBX Feature Nam

Define Outboard Proxy SIP Feature Access Codes (FACs) In order to define the FNEs for the Outboard Proxy SIP features listed in Table 3, a FAC must also be specified for each feature. Use the change dialplan analysis command to specify the format of the FAC, and then the change feature-access-codes command to define the codes themselves. change dialplan analysis Page

5.1.3. Define Feature Name Extensions (FNEs) Now the FNEs can be defined using the change off-pbx-telephone feature-name-extensions command. It is recommended that a uniform format for these extensions be used as shown (e.g., all beginning with 70xxx), so that the definition of the address map in the Avaya Converged Communications Server later (Section 5.2) will be as simple as possible. change off-pbx-telephone feature-name-extensions Page 1 of 1 EXTENSIONS TO C

5.1.5. Add stations Use the add-station command to add a station for each SIP phone to be supported. Use 4620 for the Station Type and be sure to include the Coverage Path for voice messaging if it is available. Use the COS value specified in the previous section. The Name field is optional and is shown on the display of the destination phone when making calls. Use default values for the other fields on Page 1.
