Item Description
Transport Layer Protocol
•
UDP —Specify UDP as the transport layer protocol to be used during the
subscription.
•
TCP —Specify TCP as the transport layer protocol to be used during the
subscription.
•
TLS —Specify TLS as the transport layer protocol to be used during the
subscription.
By default, UDP is adopted.
URL Scheme
•
SIP —Specify SIP as the URL scheme to be used during subscription.
•
SIPS —Specify SIPS as the URL scheme to be used during subscription.
By default, SIP is adopted.
Server Address
Specify the voice mailbox server address, which can be either an IP address or a
domain name.
Port Number Specify the port number of the voice mailbox server.
Subscription Valid Time Specify the effective time of the subscription.
Re-subscription Time Specify the subscription retry interval.
Voice Mailbox Number Set the voice mailbox number.
Binding Mode
•
Binding Mode —The MWI function is bound with the voice mailbox and the
voice mailbox server has set up subscription information for the UA. Therefore,
the UA can receive NOTIFY messages without sending SUBSCRIBEs to the voice
mailbox server.
•
Non-binding Mode —The voice mailbox server does not set up subscription
information for the UA automatically, so the UA has to send a SUBSCRIBE to the
server and after that it can get NOTIFY messages from the server. Non-binding
mode includes two categories:
Loose Match —Strict consistency check is not needed, so the call ID that the
NOTIFY is sent to can be different from the call ID that proposed the
subscription.
Strict Match —Strict consistency check is needed, so the call ID that the
NOTIFY is sent to must be the same as the call ID that proposed the
subscription.
Generally, the voice gateway sends a SUBSCRIBE to the server, and receives a NOTIFY from the server
if the subscription is successful, and gets the status of the voice mailbox afterwards.
