WIRELESS PARTY LINE
The FreeSpeak basestation provides five wireless party line groups
which allow up to twenty eight members to be connected together in a
conference call. The beltpack keys assigned to the wireless party line
group are assigned as dual talk and listen and party lines connected to
the group are assigned as talk and listen.
When a beltpack or party line talks to a wireless party line group the
talk signal from the beltpack or party line is subtracted from the listen
signal to remove the sidetone resulting from the users voice being
looped back in the conference audio, leaving only the audio from other
members.
