Configuring Basic Features
85
180 ring workaround defines whether to deal with the 180 message received after the
183 message. When the caller receives a 183 message, it suppresses any local ringback
tone and begins to play the media received. 180 ring workaround allows the IP phone
to resume and play the local ringback tone upon a subsequent 180 message received.
Procedure
180 ring workaround can be configured using the configuration files or locally.
