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, Quadro 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 Quadro.
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.

Remote Settings
This group is used to configure
SIP Remote Extension
functionality. This is an advanced telephony feature that allows Quadro users to remotely
operate Quadro. Users need to register a hardware or software SIP phone on the Quadro by defining the Quadro’s global IP address and an
appropriate Username/Password. A registered SIP Remote phone can act fully as a phone connected locally to Quadro, i.e. it can use Quadro’s PBX
features, place and receive calls, access voice mails, etc.
The
Enable
checkbox activates the SIP Remote Extension’s functionality.
Please Note:
SIP Remote Extension
functionality may be enabled only for active (attached to an onboard FXS or IP line) extensions.
Identification parameters used by the remote SIP device for registration on the Quadro should be defined in the
Username
and
Password
text
fields. They should match on both Quadro and SIP phone for a successful connection. The
Password
field is checked against its strength and you
may see how strong is your inserted password is right below that field. To achieve the well protected strong password minimum 8 characters of
letters in upper and lower case, symbols and numbers should be used. If you are unable to define a strong password, press
Choose Generated
Password
to use one of system defined strong passwords.
Line Appearance
text field requires a number of simultaneous calls supported by the SIP phone.
When the
Enable RTP Proxy
checkbox is selected, incoming and outgoing RTP streams to and from the remote SIP phone will be routed through
Quadro. When the checkbox is not selected, RTP packets will be moving directly between peers.
