GVC3210 Administration Guide
Version 1.0.1.21
Callee Request
Timer
This is used to set the c
allee party to act as refresher. If set to “Yes” and both parties
support session timers, the device will enable the session timer feature when it
receives inbound calls. The SIP 2
00 OK will include the content “refresher=uas”.
The default setting is
“No”.
Force Timer
It is used to activate the session timer feature on the device. If it is set to
“Yes”, the
device will use the session timer even if the remote party does not support this feature.
If it is set to “No”, the device will enable the session timer only when the remote party
supports this feature. To turn off the session timer, select
“No”.
The default setting is
“No”.
Enable 100rel
It is used to activate the PRACK (Provisional Acknowledgment) method. This option
is very important to support PSTN internetworking. PRACK improves the network
reliability by adding an acknowledgement system to the provisional Responses (1xx).
If
set to “Yes”, the device will respond to the 1xx response from the remote party.
The default setting is
“No”.
Caller ID Display
It is used to set the header tag from the SIP INVITE message for the Caller ID display.
If it is set to Auto, the device will use one of the available headers in the priority
hierarchy of P-Asserted Identify Header, Remote-Party-ID Header and From Header.
If it is set to “From Header”, it will use the From Header information for the Caller ID.
If it is set to “Disabled”, all the incoming calls Caller ID will be displayed with
“Unavailable”. The default setting is “Auto”.
Use Privacy
Header
Controls whether the Privacy header will present in the SIP INVITE message or not,
whether the header contains the caller info. When set to “default”, the Privacy Header
will show in INVITE only when “Huawei IMS” special feature is on. If set to “Yes”, the
Privacy Header will always show in INVITE. If set to “No”, the Privacy Header will not
show in INVITE. The default setting is “Default”.
Use P-Preferred-
Identity Header
It is used to set if the P-Preferred-Identity Header will be presented in the SIP INVITE
message. If set to “default”, the P-Preferred-Identity Header will be omitted in SIP
INVITE message when
“Huawei IMS” special feature is active. If set to “Yes”, the P-
Preferred-Identity Header will always be presented. If set to
“No”, it will be omitted.
The default setting is
“Default”.
SIP Transport
It is used to set the protocol used to transport the SIP message. It can be selected
from TCP/UDP/TLS. The default setting is
“UDP”.
SIP URI Scheme
when using TLS
It is used to set SIP header
– “SIP” or “SIPs”, which will be used if TLS is selected for
SIP Transport. The default setting is
“SIP”.
Use Actual
Ephemeral Port
in Contact with
TCP/TLS
It is used to set the port information in the Via header and Contact header of SIP
message when the device uses TCP or TLS. If set to
“No”, these port numbers will
use the permanent listening port on the device. Otherwise, they will use the ephemeral
port for the particular connection. The default setting is
“No”.
Symmetric RTP
It is used to enable the symmetric RTP mechanism. If
set to “Yes”, the device will use
the same socket/port for sending and receiving the RTP messages. Default is
“No”.
