SIP related configuration

The SIP messages consist of request message and response message. Both include SIP message
header field and SIP message body field. SIP message header maily describes the message sender and
receiver; SIP message body mainly describes the specific implementation method of the dialog.

Message of request:

the SIP message sent by a client to the server, for the purpose of activating the

given operation, including INVITE, ACK, BYE, CANCEL, OPTION and UPDATE etc.

Message of response

: the SIP message sent by a server to the client as response to the request,

including 1xx, 2xx, 3xx, 4xx, 5xx, and 6xx responses.

Message header

: Call-id.

Parameter line

: Via, From, To, Contact, Csq, Content-length, Max-forward, Content-type, White

Space, and SDP etc.
VG gateways provide good flexibility in content setting in order to improve the compatibility with
the platform.
After login, click the label of “Advanced > SIP” to open this interface.

SIP related configuration parameter

Title

Explanation

SIP related
configuration

MWI subscription

The default is 86400 seconds. The gateway will send platform a message
to confirm that has subscribed MWI service at intervals of the time
period set here. This parameter should be used in conjuection with voice
mail subscription on the page of subscriber line.

PRACK

Determine whether to activate Reliable Provisional Responses. (RFC
3262)

Session timer

Choose to activate session refresh (Session Timer, RFC 4028). By
default, session timer is not activated.

Session interval

Set the session refresh interval, the gateway will enclose the value of
