12.11 Call Completion 
When the user places a call and the callee is temporarily unavailable to answer the call, SIPMMI will save 
the callee’s number and use the SUBSCRIBE/NOTIFY method to subscriber callee’s status. 
When the phone receives NOTIFY message with “terminal” status: 
•  If the phone is idle, the phone screen will prompt whether to dial the number; If yes, the phone will 
dial the last outgoing failed number. 
•  If the phone is not idle, the phone will not prompt until the phone is idle. 
The following table lists the parameters you can use to configure Call Completion feature.

12.12 Automatic Call Distribution (ACD) 
ACD enables the use of IP phones in a call-center role by automatically distributing incoming calls to 
available users or agents. You can enable users to use their phone in a call center agent/a supervisor role 
on a supported call server. 
The users can sign in and sign out of the ACD state as call center agent using soft keys. The server 
distributes calls to the agent when the agent state is available, and stops distributing calls when the agent 
changes state to unavailable. 
The IP phone remains in the unavailable status until the agent manually changes the IP phone status. You 
can configure how long the IP phone remains unavailable state and changes to available automatically on a 
supported call server. The methods you use vary with the SIP server you are using. 
12.12.1 ACD Key Configuration via Phone UI 
You can configure a soft key as ACD key to log into the ACD system. The ACD key on the IP phone 
indicates the ACD state. 
On the phone, select one soft key, long press it for 2s, and select Key Type as ACD.
