Avaya supports four categories of Presence/IM devices:
  • Category 1: Next-generation SIP mode
  • Category 2: SIP mode
  • Category 3: H.323 mode
  • Category 4: Non-Presence/IM capable
Category 1 devices
Category 1 devices are strongly recommended because the devices:
  • Are more resilient to network or server outages.
  • Support Presence/IM features such as High Availability and Geo Redundancy.
  • Support higher overall capacity in a multi-node Presence Services cluster deployment as the resources are used more efficiently.
  • Do not need an end user to administer Presence Services information on device.
  • Do not need an end user to change device settings if a user’s home Presence Services cluster changes.
The Category 1 devices do not need an end user to administer a Presence Services address or an Avaya Presence/IM communication address. Instead, the device automatically gets this information through Personal Profile Manager (PPM) web service of Session Manager. The Presence Services address is returned as a Fully Qualified Domain Name (FQDN), which the device resolves to one or more IP addresses using DNS. FQDN addressing is required for Presence Services features such as High Availability and Geo Redundancy.
Example
  • Avaya one-X® Communicator SIP 6.2.6 or later
Category 2 devices
Category 2 devices require an end user to administer a Presence Services address, and an Avaya Presence/IM communication address. The Presence Services address is usually administered as an IP address. The end user logs in using SIP mode.
Example
  • Avaya Workplace Client 3.10 or above for Windows
  • Avaya one-X® Communicator SIP pre-6.2.6
Category 3 devices
Category 3 devices require an end user to administer a Presence Services address, and an Avaya Presence/IM communication address. The Presence Services address is usually administered as an IP address. The end user logs in using H.323 mode.
Example
  • Avaya one-X® Communicator H.323
Category 4 devices
Category 4 devices are typically hard desk phones that:
  • Do not support the SIP or XMPP protocol for presence and IM.
  • Do not have the ability to exchange messages with other devices.
  • Do not have the ability to publish their own presence state information.
Example
  • Avaya 9600 series H.323 phones
  • Avaya 96X1 series H.323 phones
  • Avaya digital and analog desk phones
