to the number of TDM lines.
The required number of HG 1500 boards for VoIP is determined by the sum of the gateway
channels, MOH channels and conference channels

MOH Channels (G.711, G.723, G.729)

A DSP channel is used to provide MOH for IP workpoint clients. Depending on the configuration
(HiPath 3000 Manager E), up to five DSP channels can be used for MOH.
A maximum of 10 MOH data streams per HG 1500 board are possible. This means that up to
10 IP workpoint clients can simultaneously hear MOH.
A DSP channel is required for each codec (G.711, G.723, G.729), irrespective of the number
of MOH data streams. If more than 10 MOH data streams are required, additional HG 1500
boards must be used.
A B channel license is not required for MOH.
