SIP Gateways and SIP Proxies are different but are configured in a very similar manner. Both types of
devices are added to the system through the Phone System / Outside Lines page.
10.4.1 Configuration
SIP Proxies and SIP Gateways have configuration settings that are specific to the ITSP or device being used.
To configure a new SIP Proxy, click the add new SIP Proxy
link. It will open a page with parameters that need
to be configured specifically for the ITSP service being used. Use the add new SIP Gateway
link to define a
new gateway. Once a SIP Proxy or SIP Gateway is defined on the Outside Lines page, it is necessary to
enter the configuration screen again to configure Advanced Settings. Click the Modify
link to make
adjustments to the Advanced Settings.
10.4.2 Details about SIP Proxies
Account Settings
Description
– This field is used to assign a name to the SIP Proxy. It can be the ITSP name or any name that
is useful to the System Administrator.
User ID
– The ITSP typically assigns this value. This ID is often the phone number for the account.
SIP Server
– This is the DNS name or IP address of the proxy server you are connecting to. This is obtained
from the ITSP. A port number is usually 5060 but it should be verified with the ITSP.
Outbound Proxy
– This is the DNS name or IP address of the outbound redirect server if it is different from
the SIP Server. In many cases this is not required.
SIP Registration Required
– If your SIP proxy server requires a SIP registration, check the box indicating this
and fill in the Login ID and Password assigned by the ITSP. If the ITSP uses a registrar server that is different
than the SIP proxy server, enter the DNS name or IP address of this server in the Registrar name field.
Caller ID Name
– The Caller ID name that will be used for outbound calls. Some ITSPs may ignore this or
refuse calls if set.
Caller ID Number
– The Caller ID Number that will be used for outbound calls. Some ITSPs may ignore this
or refuse calls if set.
Maximum Active Calls
– The Allworx server will use this number to limit the total number of the incoming and
outgoing active calls with this SIP Proxy. This is useful for controlling the network bandwidth used, since it is
assumed by Allworx that the SIP proxy is not a LAN local service.
Number of Line Appearances
– This field defines the number of Line Appearances you would like defined for
this Proxy so that Allworx will create a virtual set of phone lines that mimic real physical analog phone lines
on this service. This is a feature unique to Allworx and allows ITSP services to be used in a conventional key
system manner. Typically, this number matches the maximum number of active calls limit set above, but it
can be less.
Note: Set a value of zero if Line Appearance functionality is not required.
Send Digits as Dialed
– Specifies that outbound numbers should always be sent exactly as dialed on the
handset placing the call. In most cases, you want the number converted into NANPA dialing form, so this box
