Handset, Speakerphone and Headset Mode

The call can be switched between the handset and speaker/headset modes. To switch  between handset and speaker/headset mode, press the hookswitch or SPEAKER .

Multiple SIP Accounts and Lines

The ET523 can support up to four independent SIP accounts. Each of the four line keys (LINE1–LINE4) is mapped to one SIP account. In off-hook state, when you press the corresponding Line key or continuously press the same line key, the phone will switch among the four accounts. If the name of an account is configured, then it is displayed on the LCD and a dial tone is heard.

For example: configure Account Name of the four SIP accounts as AAA, BBB, CCC

and DDD. Ensure each account is activated and registered on the VoIP server or 

IP-PBX. When LINE1 is pressed, you will hear a dial tone and see AAA on the LCD display; when LINE2 is pressed, you will hear a dial tone and see BBB on the LCD display, and the operation result is as same as pressing LINE3 and LINE4. The same function can also be performed when you press any idle Line key continuously. The LCD displays the used account and the dial tone can be heard.

To make a call, select the line you wish to use. The LED of the corresponding line will light up. Switch lines before dialing by pressing the same LINE key continuously until the desired account is displayed on the LCD and the dial tone is played.

For example: when LINE1 is pressed, the LCD displays AAA; If LINE1 is pressed twice, the LCD displays BBB and the subsequent call will be made through SIP account 2 BBB.

When the phone is idle, press the corresponding key to answer the incoming call

Making a Call by Using an IP-Address

Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a SIP proxy. VoIP calls can be made between two phones when:

 Both phones have public IP addresses.

 Both phones obtain the private or public IP addresses on the same LAN/VPN

network.

 Both phones can be connected through a router by using public or private IP

addresses (with configuring a valid port or DMZ). All the necessary ports should be open to the two phones. To make a direct IP call, do as follows:

Step 1

Press OK to access the main menu.

Step 2

Select Direct IP Call by using the navigation keys.

Step 3

Press OK to select.

Step 4

Input the 12-digit target IP address.

Step 5

Press OK to initiate the call.

For example, if the target IP address is 192.168.1.60 and the port is 5062 (such as

192.168.1.60:5062), input192*168*1*60#5062. The * key represents a dot “.”; and the

(25)

For example:

 192.168.0.2 calls 192.168.0.3—dial #*3, followed by SEND.

192.168.0.2 dials #*3; #*03; or  #*003, which means the same––call 192.168.0.3.

 192.168.0.2 calls 192.168.0.23––dial #*23, followed by SEND.  192.168.0.2 calls 192.168.0.123––dial#*123, followed by SEND.

If the SIP Server is configured, a Direct IP-IP call still works. If you use the STUN, the Direct IP-IP call will also use the STUN. Set Use Random Port

to No when completing Direct IP calls.

IP Address The ET523 operates in two modes:

DHCP/PPPoE mode: All the field values for the static IP mode are not used (even though they are still saved in the Flash memory). The ET523 acquires its IP address from the first DHCP server it discovers on its LAN. The host name and the domain name can be assigned by either DHCP server or  manually. Preferred DNS can be changed but not recommended because the DHCP server handles all these.

 Host Name and Domain Name: The special DHCP

options that are added to the DHCP Discover and DHCP Request after configuration.

 Preferred DNS: It overrides other DNS servers we

received from DHCP or PPPoE if configured

To use the PPPoE feature, the PPPoE account settings need to  be set. The ET523 will attempt to establish a PPPoE session if 

any of the PPPoE fields is set.

Static IP mode: Configure all of the following fields: IP address, Subnet Mask, Default Router IP address, DNS Server 1 (primary), DNS Server 2 (secondary). These fields are set to zero by default.

Description

Daylight Savings Time

This parameter controls whether to set the displayed time to the daylight savings time. If it is set to Yes and the optional rule is empty, then the displayed time will be 1 hour ahead of  the normal time.

The daylight savings time will be automatically adjusted according to the rule set in the Optional Rule field. The rule syntax include: start-time end-time and saving. Both

start-time and end-time have the same syntax: month, day, weekday, hour, minute.

 Month: 1,2,3, …, 12 (for Jan, Feb, .., Dec)  Day: [+|-]1,2,3, …, 31

 Weekday: 1, 2, 3, …, 7 (for Mon, Tue, .., Sun), or 0 that

means the daylight saving rule is not based on weekdays  but based on the day of the month.

 hour: hour (0–23)

 minute: minute (0–59)

If weekdayis set to 0, it means the daylight saving time starts or ends at the given date. In this case, theday value cannot be negative. If weekday is not set to 0 and the day value is

 positive, then the daylight saving time starts on the first “day” iteration of the weekday (such as 1st Sunday, 3rd Tuesday etc).

If weekday is not set to 0 and the day value is negative, then the daylight saving time starts on the last “day” iteration of  the weekday (last Sunday, 3rd last Tuesday etc).This feature is supported on the phone only when you have correctly set the NTP server.).

The saving takes “minute” as the unit. The saving time may also be preceded by a negative (–) sign if subtraction is

desired instead of addition.

When the default Automatic Daylight Saving Time Rule

value is set to 3,2,7,2,0;11,1,7,2,0;60, which complies the rule of US.

For example:

US/Canada where daylight saving time is applicable: 03,02,7,02,00;11,1,7,02,00;60.

This means the daylight saving time starts from the second Sunday of March at 2 am and ends on the first Sunday of   November at 2 am. The saving is 60 minutes.

Field

Description

Voice Frames  per TX

This field contains the number of voice frames to be transmitted in a single Ethernet packet (be advised the limit is based on the maximum size of Ethernet packet, 1500 byte or 120 kbps). When setting this value, you should pay attention to the requested packet time (ptime used in SDP message). This

 parameter is associated with the first codec in the above codec  preference list or the actual used payload type negotiated

 between the 2 conversation parties at the running time. For  example, if the first codec is configured as G.723 and the Voice Frames per TX is set to 2, then the ptime value in the SDP message of an INVITE request will be 60 ms because each G.723 voice frame contains 30 ms of audio. Similarly, if this field is set to 2 and the first codec is G.729 or G.711 or G.726, then the ptime value in the SDP message of an INVITE request will be 20 ms.

If the configured voice frames per TX exceeds the maximum value, the IP phone will use and save the maximum permitted value for the corresponding first codec choice. The maximum value for PCM is 10 (x10ms) frames; for G.726, it is 20 (x10ms) frames; for G.723, it is 32 (x30ms) frames; for G.729/G.728, 64 (x10ms) and 64 (x2.5ms) frames respectively.

Pay attention to editing these parameters. Adjusting these  parameters will also change the dynamic jitter buffer. The

 phone has a patent dynamic jitter buffer for handling algorithm. The jitter buffer range is 20–200 ms.

You are recommends to use the default settings, and not to change these parameters as a common user. Incorrect settings will affect the voice quality.

Layer 3 QoS This field defines the Layer 3 QoS parameter. It is the value used for IP Precedence or Diff-Serv or MPLS. The default value is 48.

Layer 2 QoS This contains the value used for Layer 2 VLAN tag. The default setting is blank.

 No Key Entry Timeout

The default value is 4 seconds. Dialed number will be sent out after this set duration without pressing SEND

Use # as Dial Key

This parameter allows users to configure the # key as the

SEND. If it is set to Yes, the # key will immediately send the call. If it is set to No, the # key is included as part of the dial string.

Description

Local RTP port This parameter defines the local RTP-RTCP port pair used to listen and transmit messages. It is the base RTP port for channel 0. When it is configured, channel 0 will take this port_value as RTP port value, and port_value+1 as the RTCP port value; channel 1 will take port_value+2 as the RTP port value and  port_value+3 as the RTCP port value. The default value is

5004. Use Random

Port

When this parameter is set toYes, the 523 will force the random generation of both the local SIP and RTP ports. This is usually necessary when multiple ET523s are behind the same NAT. The default value is No.

Keep-alive interval

This parameter specifies how often the ET523 sends a blank  UDP packet to the SIP server in order to keep the “hole” on the  NAT router open. The default value is 20 seconds. The

minimum value is 10.

Use NAT IP NAT IP address used in the SIP/SDP message. The default setting is blank.

STUN Server IP address or Domain name of the STUN server. The STUN resolution result will display in the STATUS page of the Web configuration page. STUN NAT resolution does not work for  symmetric NAT. STUN is a client-server protocol. A VoIP  phone or software package may include a STUN client, which

will send a request to a STUN server. The server then reports  back to the STUN client what the public IP address of the NAT

router is, and what port is opened by the NAT to allow incoming traffics back to the network.

Firmware Upgrade and Provisioning

This radio button will enable the ET523 to download the firmware or configuration files through either HTTP or local TFTP server.

(45)

Field

Description

Via TFTP This is the IP address of the configured TFTP server. When it is selected, if the value is non-zero or not blank, the ET523 will attempt to retrieve a new configuration file or a new code image from the specified TFTP server at the boot time. With three attempts before timeout, it will start the boot process with the existed code image in the Flash memory. If a TFTP server is configured and a new code image is retrieved, the new

downloaded image will be verified and then saved into the Flash memory.

Note:

When adopting the TFTP upgrading software, you are strongly recommended to upgrade the firmware in the local LAN environment. Do not interrupt the TFTP upgrade  process (especially the power supply) to prevent from

damaging the device.

Via HTTP The URL of the HTTP server used for firmware upgrade and configuration through HTTP, such as:

http://um.huawei.com/etphone:6688/.
