Registration on SIP Server
enables the SIP server registration option. If the extension has already been registered on an SIP server, its IP address will be
displayed in brackets.
Please Note:
If
the ITSP does not require each DID to uniquely register to the external SIP server, then only enter the DID number in the
User Name/DID
Number
field. The other fields are not required.

SIP Advanced
Settings
This group is used to configure advanced SIP settings (Outbound Proxy, Secondary SIP Server and Outbound Proxy for the Secondary SIP Server settings
and to define other SIP server specific settings).
The SIP Outbound proxy is an SIP server where all the SIP requests and other SIP messages are transferred. Some SIP servers use an outbound proxy
server to escape restrictions of NAT. For example, Free World Dialup service uses an Outbound Proxy server. If an Outbound proxy is specified for an
extension, all SIP calls originating from that extension are made through that outbound proxy, i.e., all requests are sent to that outbound proxy, even those
made by Speed Calling.
The Secondary SIP Server acts as an alternative SIP registration server when the primary SIP Registration Server is inaccessible. If the connection with the
primary SIP server fails, QX will automatically start sending SIP messages to the Secondary SIP Server. It will switch back to the primary SIP server as soon
as the connection is reestablished.
Authentication User Name
requires an identification parameter to
reach the SIP server. It should be provided by the SIP service
provider and can be requested for some SIP servers only. For others,
the field should be left empty.
Send Keep-alive Messages to Proxy
enables the SIP registration
server accessibility to the verification mechanism.
Timeout
indicates the timeout between two attempts for the SIP registration
server accessibility verification. If no reply is received from the
primary SIP server within this timeout, the Secondary SIP server
will be contacted. When the primary SIP server recovers, SIP
packets will resume being sent to it.
The
RTP Priority Level
drop down list is used to select the priority
(low, medium or high) of the RTP packets sent from a
corresponding extension. RTP packets with higher priority will be
sent first in case of heavy traffic.
The
Do Not Use SIP Old Hold Method
checkbox enables the new
recommended method of call hold in SIP, in which case the hold
request is indicated with the "a=sendonly" media attribute, rather
than with the IP address of 0.0.0.0 used before. The checkbox should
be enabled if the remote party does not recognize hold requests
initiated from the QX.
A group of
Host address
and
Port
text fields respectively require
the host address (IP address or the host name) and the port
numbers of the
Outbound Proxy
,
Secondary SIP Server
and the
Outbound Proxy for the Secondary SIP Server
. These settings are
provided by the SIP servers’ providers and are used by QX to reach
the selected SIP servers.

Voice Mailbox Settings
The
Voice Mailbox Settings
(available only for QXFXS24 Gateways) are used to manage Voice Mail service for the corresponding extension and to define
the location where voice mails will be collected.
This group is used to configure voice mailbox storage and consists of a group of manipulation radio buttons to define the location where voice mails will
be collected.
•
Disable Voice Mail
– disables the Voice Mail service for the corresponding extension. With this selection, the extension user will be unable to reach
their Voice Mail Settings, but will be able to access their Voice Mailbox and manage the existing voice mails.
