Ware. This feature is enabled by a CSK; QSIG_OPTION.
Switched voice calls over the ISDN B-channels are controlled by D-channel
Common Channel Signaling messages. The BRI B-channel voice traffic is
compressed and packetized before transmission over either Frame Relay or IP. Voice
compression and packetization is performed between Vanguard nodes. The PCM
(Pulse Code Modulated) format is used between the Vanguard node and a PBX.
