For example, you can use low-bit-rate vocoders to transport voice and ‘Transparent’ coder
to transport data (e.g., for D-channel). You can also use Profiles to assign ToS (for
DiffServ) per source - a timeslot carrying data or signaling is assigned a higher priority
value than a timeslot carrying voice.
For tunneling CAS trunks, set the protocol type to 'Raw CAS' (ProtocolType = 3 / 9) and
enable RFC 2833 CAS relay mode ('CAS Transport Type' parameter is set to 'CAS
RFC2833 Relay').
Note: For TDM over IP, the parameter CallerIDTransportType must be set to '0'
(disabled), i.e., transparent.
Below is an example of ini files for two devices implementing TDM Tunneling for four E1
spans. Note that in this example both devices are dedicated to TDM tunneling.
