E*phone 2.0 operating instructions

Before use, the IP address mask needs to be set. You need to set it to 255.255.248.0 (the default is 255.255.255.0).

The default sipd server is ind (128.59.19.27). If you run sipd at other host, you need to set up the sip server address.

There are two operating modes:

• Dialing by IP address. Pick up the phone, press "ENTER" until "I" appears at screen. Then dial the IP address.
• Dialing by user name. The users need to be registered via a third party, since ephone 2.0 doesn't support REGISTER.

  LCD

  There is a 120x32-dot LCD screen that is defined as a 15x4 ASCII message display. Each character takes up an 8x8 dot matrix. The message fields are defined as follow

           0  1  2  3  4  5  6  7  8  9  10  11  12  13  14
  1        K     C  C  C     H  H  :  M   M   :   S   S
  2        X     m  m  m     d  d     y   y   y   y
  3        X   
  4        I
  

  The first line is the statue line witch includes three fields. The "K" field is the current input mode. It can be any of the following modes:

  D:

  Digital number input. {0-9,*,#}

  I:

  IP address input. {0-9, .}. The "*" is used as the dot "."

  A:

  Alphabet input. {0-9, a-z, . @}. The correspond alphabet to each number on the keypad will be appear on the LCD when the key is pushed again in one minute. The alphabet appears circularly. For example, when you push 2 on the keypad, 2 will appear. But when you push it again and again, then a -> b->c->2 will come out circularly. After waiting 1 minute, the number/alphabet will be admitted.

  L:

  List input mode. List the last N address dialed. (Not supported now).

  You can switch between above different modes by push the "Enter" button before you dial the number when you pick up the handset and hear the dial tone on the phone.

  The "C" field is the statue of current working mode of the phone. It can be any of the following four statues.

  IDL:
  The phone is idle when on hook.
  CAL:
  The phone is calling.
  ANS:
  The phone is being called.
  SET:
  Enter the setting program.

  The "H, M, S" field is the time field that represents for hour, minute and second respectively. It will display the current time you setting. However, when the call is connected, it will display the call duration from 00:00:00.

  The second and third lines, "X", are the message fields for SIP message. However, when the phone is on hook, the current setting month, day, and year will be displayed at the "m", "d" and "y" field respectively.

  The last line, "I", is the input field. When the input exceed right border, the screen will scroll up.

  Keypad

  There are total 17 keys on the keypad. They are 0-9, *, #, Enter, Redial, Up, Down, Hands-free.
  • "*" is used as the "." in IP input mode.
  • "Enter" is used for start the call after the address is input, or switch among the input modes before input the address, or enter the setting program when the phone is on hook.
  • "Redial" is used to redial the last address.
  • "Up" and "Down" are not effective now.
  • "Hands-free" key is toggle key for hook switch.

  Power

  The SIP phone uses the AC or DC power input of 7-12V.

  SIP messages

  When dialing in alphabet or digital mode, the input address should be in the format of name@domain or digit@domain . However, if only the name or the digit is input and the "Enter" key is pushed, SIP phone will add the default domain address to the name and digit. For example, if the cs.columbia.edu is the defalut domain address after setting.

  Input    jyin 
  Becomes  jyin@cs.columbia.edu
  

  statue message

  Currently, SIP phone supports a subset of SIP status responses. If a status code is not supported, it will be displayed as "status, unknown" format. This does not affect its normal operation.

  Installation

  There is one RJ-45 socket and one power socket at the backside of the phone. Plug the Ethernet 10Base-T RJ-45 cable on the RJ-45 socket and plug the AC or DC 7-12V power from an adapter. Then the following message will be displayed on the screen.

  D IDL 00:00:00

  The timer will increase 1 by one second. The green light is the power indication, while the red one it for Ethernet connection.

  Configuration

  Before using the SIP phone, you need to configurate it. You can start the setting program by press the "Enter" button when the phone is on hook. As long as the setting program begin, you can't stop it before finish it. When finish, it will return to idle status.

  The following items need to set: User name, host name, domain name, year, month, day, hour, minute, second, this host IP address, mask address, SIP server IP address, gateway IP address.

  You can skip any of the setting items by just press the "Enter" button.

  Dialing

  Here are some steps for dial a call.
  1. Pick up the handset (or push the Hands-free button).
  2. You can hear the dial tone.
  3. Choose the dial mode by press the Enter button.
  4. Dial the address.
  5. Press the Enter button for committing and start the call.

  Cancel a call

  Place handset back on hook. (Or push the Hands-free button if you hook off by pushing it).

  Where the call goes

  When dialing by IP address, the call directly sends to that IP address. When dial by other modes, the call is sent to SIP server.

  Redirecting Call

  The redirect calls are relay on the SIP redirect server. When the server receive the request, it should respond with the 302 status along with a "Contact" header of the destination. The SIP phone will automatically initiate a call to the new address. However, since SIP phone does not support the DNS protocol now, the "Contact" header should be in the format of: User@IP_address. Besides, the SIP phone will only call to the first "Contact" header if several "Contact" headers are included.
