ZIP2x2 User’s Manual
In Normal Network mode, you can configure the phone with up to eight VLANs, referred to as
A, B, C, D, E, F, G, and H. Each Ethernet circuit can be on a different VLAN. The following
restrictions must be considered when configuring the VLANs through the Web Interface:
• The Phone Circuit is always untagged (U) on VLAN A and is always excluded (E) from all
other VLANs.
• Each VLAN must have a different ID number.
• Each circuit can be an untagged member (U) of no more than one VLAN.
• If you configure one or more ports as a tagged (T) member of a VLAN, you must configure the
CoS setting (cos_setting). This setting is only used by the phone circuit.
The Phone Port L2 CoS parameter configures the Class of Service (CoS) at layer 2 for the phone
port. Values range from 0 to 7.
E.6.2 SIP Communications
The SIP Communications panel, as shown in figure E-19, displays the parameters required by the
phone to communicate with the SIP proxy and registrar servers. The SIP Communications panel
displays the configuration options for the following parameters:
Proxy Address. This parameter is the IP address of the server that handles call control for the
phone. Section 8.5.3.1 on page 109 describes the equivalent menu command.
Proxy Port. This parameter is the TCP or UDP port that the phone uses to send SIP messages. The
default value is 5060. Section 8.5.3.1 on page 109 describes the equivalent menu command.
Register with Proxy. When enabled, the phone registers with the registrar server if specified;
otherwise phone registers with proxy server. Phone does not register with either server when
option is disabled.
Proxy Password. The proxy password authenticates the phone to proxy servers that require
authentication. Section 8.5.3.1 on page 109 describes the equivalent menu command.
Registration Expires. This parameter specifies the time period, in seconds, after which a
REGISTRATION expires. This value is inserted into the Expires header field.
Subscription Expires. This parameter specifies time period, in seconds, after which a SUBSCRIBE
expires. This value is inserted into the Expires header field.
Backup Proxy Address. This parameter displays the IP address of the backup proxy server. The
phone will attempt to switch to the backup proxy if the primary proxy server fails to operate.
Section 8.5.3.2 on page 110 describes the equivalent menu command.
Backup Proxy Port. This parameter specifies the TCP or UDP port number of the backup proxy.
The default value is 5060. Section 8.5.3.2 on page 110 describes the equivalent menu command.
Register with Backup Proxy. When this parameter is enabled, the phone registers with the
backup proxy at start up. Section 8.5.3.2 on page 110 describes the equivalent menu command.
Backup Registration Expires. This parameter specifies the time period, in seconds, after which a
REGISTRATION expires for the Backup proxy. This value is inserted into the Expires header field.
Registrar Address. This parameter specifies the SIP registrar server address. When this value is set,
phone attempts to register with this server instead of the proxy server. Section 8.5.3.3 on page 111
describes the equivalent menu command.
