2.3.9 Transferring a Call

Take the following steps to transfer an ongoing call to another phone number.
1 During the ongoing call, press the Transfer key.
2 The next available line automatically activates. Ensure you can hear a dial tone.
3 Dial the number to which you want to transfer the call.
4 To transfer the call, either:
• Wait until you hear the ringing tone, then simply put down the handset, press the
Speaker key or the Headset key (depending on which you are using) to end the call.
The call is transferred. This is known as a blind or unsupervised transfer.
• Wait for the other person to answer, then end the call. This is known as a consultant or
supervised transfer, and allows you to ask the other person whether they want to
receive the call or not.

2.3.10 Upgrading the Phone's Firmware

When it is time to upgrade your phone's firmware, your telephone network administrator will
configure the IP PBX to which the V300 is connected to automatically check your phone's
existing firmware and compare it to the firmware on an official ZyXEL server. If your
firmware's version number does not match, the IP PBX will then initiate the upgrade process:
1 When the IP PBX is ready to process your phone, it rings you while the phone is on the
hook. As soon as you answer, an automated message asks if you want to change your
V300's firmware.
2 Enter * 9 9 # on the V300's keypad to answer 'Yes'.
Enter # 9 9 # on the V300's keypad to answer 'No'.
3 If you entered 'Yes', then the phone begins downloading the new firmware from the IP
PBX. The download and install process may take some time, depending on the size of
the update and any network congestion.
4 When the download and install process completes, the V300 restarts. You may need to
log into your account again.
Do not turn off or attempt to use your V300 during a firmware update.
