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.
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 Quadro to reach the selected SIP servers.

4. Voice Mailbox Settings
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.
• Use Internal Voice Mail – enables the Voice Mail service for the corresponding extension and defines the Quadro’s internal storage as a
location for the Voice Mails.
• Use External Voice Mail – enables the Voice Mail service
for the corresponding extension and is used to define a
remote Voice Mail Server as a location for the Voice Mails.
In this case recorded voice mails will be collected on the
remote server. Radio button selection enables a sub-group
of manipulation radio buttons:
• If the remote Voice Mail Server is combined with
the SIP Proxy server, it is recommended to select
Proxy Controlled Mailbox Type. With this
selection, SIP proxy will keep the recorded voice
mail on itself. When extension accesses his
mailbox by dialing *0, the call will be redirected to
the voice mailbox on the proxy server.
• If the remote Voice Mail Server acts as a
standalone location of voice mails, it is
recommended to select Independent Mailbox
Type. With this selection, Quadro redirects the
recorded voice mails to the defined remote Voice
Mail server. When extension accesses his mailbox
by dialing *0, the call will be redirected to the
remote voice mail server.
For each of these selections, it is required to enter the
SIP URI of the Voice Mail Server where voice mails of
the corresponding extension will be collected.
