7.2 Making a Call
You must obtain dial tone before you can dial a number.
Important
This type of phone is different from phones that have been in common use for
the past 100 years. On those older phones, as you press a button to dial a digit,
the phone transmits the digit to the telephone exchange. On the ZIP2, the phone
sends all the digits as a complete message and you therefore need to inform the
phone when you have entered all the digits. The phone then assembles the
complete message and sends it to the SIP server.
7.2.1 Dialling a Number
To dial a number:
1. Take the phone off hook
1
or put the current call on hold.
The phone provides dial tone to the handset or speaker.
2. Enter the digits.
The phone plays the DTMF tones to the handset or speaker as you type the digits.
3. When you have finished entering all the digits, do one of the following:
a. Press the # key.
b. Wait two to six seconds, after which time the phone assumes that you have entered all
the digits.
4. The phone sends the dialled digits. It plays no sound while doing this.
5. While the call is proceeding, the phone plays ringback tone. If you receive a fast busy tone
instead of ringback, see section 4.2.3 on page 20.
6. When the call is established (the called party has answered), begin your conversation.
7.2.2 Redial
To dial the name or number that was most recently dialled on the phone, press the Redial key
once and then press the # key. If you have not picked up the handset, the phone enables speaker
mode.

7.3.1 Ringback
Ringback is the tone that a caller hears after dialling a number.
