For tunneling of E1/T1 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' - refer to ''Configuring the Voice Settings'' on page 67).
Note:
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.

SIP User's Manual
For TDM over IP, the parameter CallerIDTransportType must be set to '0'
(disabled), i.e., transparent.
