I am not sure about the term hyperthreading but mulitthreading is supported here is a extraction from the ctios admin guide
ICM Software CTI Product pdf - Section 3.10 - here is the exerpt:
: Service Layer
The Service layer sits between the connection layer and the Object Interface layer.
Its main purpose is to translate between the low-level network packets sent and
received by the connection layer and the high-level command and event messages
used in the Object Interface layer. The Service layer implements a generic
message serialization protocol which translates key-value pairs into a byte stream
for network transmission and deserializes the messages back to key-value pairs on
the receiving side. This generic serialization mechanism ensures
forward-compatibility, since future enhancements to the message set will not
require any changes at the Connection or Service layers.
A secondary purpose of the Service layer is to isolate the client from the network,
such that network issues do not block the client and vice versa. This is done via a
multi-threading model which allows user-program execution to continue without
having to “block” on network message sending or receiving. This prevents client
applications from getting “stuck” when a message is not immediately dispatched
across the network, and allows messages to be received from the network even if
the client application is temporarily blocked.
