Call Completion
When you place a call and the callee is temporarily unavailable to answer the call, call completion allows your
phone to monitor the busy party and establish a call after the busy party becomes available to receive a call.
Two factors commonly prevent a call from connecting successfully:
l
Callee does not answer
l
Callee actively rejects the incoming call before answering
Yealink phones support call completion using the SUBSCRIBE/NOTIFY method, which is specified in draft-poetzl-
sipping-call-completion-00, to subscribe to the busy party and receive notifications of their status changes.
The caller subscribes for update notifications of the dialog event from the busy party. Example of a SUBSCRIBE
message:
SUBSCRIBE sip:[email protected]:5060 SIP/2.0
Via: SIP/2.0/UDP 10.10.20.32:5060;branch=z9hG4bK2880274891
