Polycom VVX 250 settings

This reference describes all the settings associated with the Polycom VVX 250 phone.

Note: To align with Poly VVX phone manufacturing processes and to allow for correct firmware updates, Genesys Cloud includes a setting on the Base Settings configuration page for certain VVX phones. This setting requires telephony administrators to select which host name format the VVX phones in their organization use based on the following conditions:

VVX phones manufactured before June 2022, use either the legacy host name format or the RFC 1035 host name format.
VVX phones manufactured after June 2022 only use the RFC 1035 host name format.

For more information, see Choose a hostname format for VVX phones.

For information on creating the actual phone configuration in Genesys Cloud, see Create the base settings and Create a phone.

Base settings

Before you create a phone, create a Base Settings configuration for that phone model. The Base Settings configuration contains a group of settings that define how a particular phone model operates in Genesys Cloud. After you create a Base Settings configuration, assign it to a phone with the default settings or customize the settings. This section describes the settings that you can configure when you choose to customize a Base Settings configuration.
