7.1 Technical Advisory
Attention: For manually configured IP phones, it is now required to have the SIP Registration
Timeout parameter set to 120 seconds or more on your IP phone. Values less than 120 seconds will
not be accepted by the Quadro and will cause the IP phone registration failure on the Quadro.
7.2 General hints
It is recommended to execute the update by downloading the software first to a PC located in the LAN
side of the Quadro and perform the firmware update from the LAN side. This is to ensure that the
Internet connection will not affect the upgrade process.

data is lost during upgrade:
• Call Statistics

Statistics Settings before performing the firmware update.

firmware update.

(System->Configuration Management->Backup and download all config and voice
data).
2. Perform the Firmware Update.
