Subscriptions
Upon successful registration with the Registrar, the 16CC telephone initiates the following
subscriptions for the event packages to the server defined in the parameter
IPPROXYSRVR_IN_USE:
● Message Waiting. If the MWI event package registration fails, the 16CC still accepts an
incoming NOTIFY from the server defined in the parameter SIPPROXYSRVR_IN_USE.
● Avaya-ccs-profile event (if the ENABLE_AVAYA_ENVIRONMENT parameter is 1.)
● Avaya-cm-feature-status event (if the ENABLE_AVAYA_ENVIRONMENT parameter is 1.)
● Dialog event (if the ENABLE_AVAYA_ENVIRONMENT parameter is 1.)
The initial SUBSCRIBE messages are sent with an “expires” value set by the
OUTBOUND_SUBSCRIPTION_REQUEST_DURATION parameter. This value might be
lowered by the server, depending on the server configuration.
Note:
Note: The Avaya Agent Deskphone 16CC does not support presence, and rejects any
subscription to the presence event.
After a successful EAS Agent login, the telephone subscribes to the agent status event
package. The following event package parameters received in a NOTIFY message are passed
to the UI for potential processing:
1. agentEntity
2. nativeEntity
3. currentModeInfo
4. pendingModeInfo
5. errorResponseCode
6. directAgentCallQueued
7. skills
8. messageWaiting
9. logoutReasonInfo
10. auxReasonInfo
11. autoAnswer
Subscriptions are refreshed in accordance with RFC 3265, Section 3.1.4.2.
