3.3. Address-of-Record (SIP AoR)
The general form of SIP address-of-record is:
“Display” <protocol:email-like-address>;tag=param
zThe “Display” field is optional. If present, it consists of any ASCII characters except
for ‘<’ and ‘>’. If the “Display” is present, the following address must be enclosed in a
paired ‘<’ and ‘>’.
zProtocol: Usually in lower case, such as “sip”, “tel” or “sips”. Note, “sip”, “tel” and
“sips” protocol names MUST be specified in lower case, which is stipulated on
RFC3261.
zemail-like-address: in the form of “user-part@domain” where user-part is optional and
the domain part could be either a dotted IP or a domain name record, such as:
[email protected]
[email protected]
192.168.3.100 (Note, the user-part is optional in direct IP dialing mode)
[phone]
z“tag=param”: Multiple parameters could be present (separated by ‘;’)

4. Startup
Basically you have the following ways to configure your IP SIP Phone.
zPress 【】
FUNC + 【】 # to activate the configuration menu and configure it via
keypad.
zUse any modern web browser to configure the phone from a PC. The default login
password for both privileged and user-level password is “0000”.
zTELNET into the phone by any TELNET client. The default TELNET port is TCP port
23, login password is as the same as your phone password set in menu-3.1 on “IP SIP
Phone v2 Keypad-TELNET Administration“ (the default phone password is “0000”)
and the max concurrency is 4. IP-Range will not apply the changes until user presses
[Ctrl] +’s’ to apply the modifications or the client disconnected by [Ctrl] +’c’.
zAuto-provision on phone startup. Please refer to “Menu-7.4 Auto-provision.” on “IP SIP
Phone v2 Keypad- TELNET Administration”.
Note, before you can configure your phone-set from your PC, such as by a TELNET
client or point your browser to the phone-set, you must have configured its IP via
keypad properly.
4.1. Prerequisite
Initially, your phone can only be configured via keypad since it bears no valid IP yet. After
finishing configuring your network, you could use either a web browser (HTTP port 80) or a
TELNET client (TCP port 23) if you have a small number phone-sets to configure.
However, we recommend you to use TFTP for auto-provision if you have to administer
large amounts of phone-sets. For TFTP provision, please refer to 12.4 Auto Provisioning on this
document.
4.1.1. Network
To configure your network:
zPress 【FUNC】+ 【#】
zGo to 【6.Network】\【1.General】
Please configure the phone based on your network configuration: DHCP, static IP or

IP SIP Phone v2 User’s Guide Mar. 2005
[18/100]
PPPoE.
4.1.1.1. DHCP
zPick【1.Mode】\【1.DHCP】
zDisable【4.Use Static DNS】by choosing 【2.DHCP】
Note: if you want to assign a different domain name server instead of using those obtained by
DHCP, you should choose【1.Static DNS】and set the IP of your specific DNS into
【5.Static DNS】, such as “1.Primary DNS” = 192.168.3.254 (modify this as necessary).
The supported DHCP options are:
zClient PC address
zDHCP option 1—Client Subnet Mask
zDHCP option 3—Gateway IP on the client’s subnet
zDHCP option 6—One or two Domain Name servers
zDHCP option 15—Domain name
zDHCP option 42—Network Time Protocol servers
zDHCP option 66 (TFTP server name)
Note: To make DHCP option 6 take effect, you must disable
【 MENU 】 => 【 6.Network 】
/ 【 1.General” / 【 4.Use static DNS 】 by picking 【 2.DHCP 】
Note: If DHCP option 42 is present, it will overwrite the SNTP server in menu-7.3.2
【 Server IP 】
Note: DHCP option 66 will overwrite the Auto-provision server in Menu-7.4.2 【 TFTP
server 】
4.1.1.2. Static IP (Fixed IP)
zPick【1.Mode】\【2.Static assign】
zGo to【2.Static Settings】, and enter your network configurations based on your ISP.
For example:
1. Host IP = 210.201.210.132 (modify this as necessary)
2. Network mask = 255.255.255.0 (modify this as necessary)
3. Gateway IP = 210.201.210.128 (modify this as necessary)
zEnable【4.Use Static DNS】by choosing【1.Static DNS】
zAssign【5.Static DNS】, such as: 【1.Primary DNS
】 = “168.95.1.1” (modify this as
necessary)
4.1.1.3. PPPoE
zPick【1.Mode】\【3.PPPoE】
zGo to【3.PPPoE settings】and enter your PPPoE authentication information, such as:
1. Login ID = MyPPPoEAccount (modify this as necessary)

3. Service Name = Optional, some ISP requires it (modify this as necessary).
4.1.1.4. Verify Network Configuration
Press 【F7】(which default is a shortcut to menu【8.Advanced】\【4.System Status】\
【1.Network】) to check current active network settings:
1 9 2 . 1 6 8 . 2 1 0 . 1 1 3
MA C :
1 9 2 . 1 6 8 . 2 1 0 . 1
It will display the host IP, Ethernet MAC address and the active DNS IP (secondary DNS IP
will be shown if available) in order.
Once finishing network configuration, you should be able to place a point-to-point call. For
example, if your phone IP is “192.168.1.10” and you want to dial another SIP phone which IP is
“192.168.1.20”, please dial “*20**5060” (or just “*20” if the target phone listens on UDP port
5060; otherwise you must dial the target UDP port as well). This is “LAN dialing” (Refer to
section 8.1-“Dialing Scheme” on this document). If the call could be set up correctly, then your
network configuration is fine; otherwise, please refer to B-1 on Appendix B-“Trouble Shooting”.
Note, if you reside on a LAN without gateway, you should specify the gateway IP as
“0.0.0.0” rather than assigning a non-existent or an invalid IP; otherwise the network packets may
not be routed correctly (which may result in no voice packets could be sent from this phone)!
This constrain applies to DHCP and PPPoE as well: DHCP and PPPoE server should not
designate a non-existent or invalid gateway.
4.1.2. SIP Service
Before you start, you should ensure you have SIP-related data from your ISP. For example,
if you get the following information from your SIP ISP:
i. Account: Michael
ii. Password: secret
iii. SIP address-of-record: [email protected]
iv. SIP Proxy / Registrar Server: sip.isp.com, which serves on UDP port 5060
Then you could configure your IP SIP Phone by a web browser as below:

IP SIP Phone v2 User’s Guide Mar. 2005
[20/100]
Alternatively, you mayo to『Main Menu』=>”6.Network” / ”2.SIP settings” / ”1.1st Realm”
to configure these information by keypad.
i. If you have applied for more than one service domains, please repeat step I and II
until all active domains are properly configured. IP SIP Phone supports three
different service domains at most.
ii. After saving the configuration, the system will try to register to those activated SIP
domains. The flashing green LED of 【Registration】key indicates that the
registration is undergoing. Once the green LED stops flashing, you could know the
registration result by the LED. Please refer to section-10.11 “Registration on
Demand” and section-10.12 “Multi-domain Registration” on this user’s guide for
detail.
iii. If you failed to register your phone to SIP registrar, please refer to Appendix
B-“Trouble Shooting” on this document.
4.1.3. Configure NAT and Firewall
If your SIP server locates on public internet, whereas your phone resides on a local area
