Is T.37 also known as the 'pass through' protocol?

T.37 is not known as the 'pass through' protocol; instead, it is primarily associated with a protocol for the delivery of fax messages over the Internet using email. The term 'pass through' typically refers to a different kind of functionality where data is forwarded without alteration or processing, which does not accurately describe T.37's role or function.

In T.37's context, the protocol enables the transmission of fax data as email attachments to support the sending and receiving of faxes through internet-based email systems. Therefore, referring to it as the 'pass through' protocol is misleading as it implies a simplicity that does not accurately capture its comprehensive functionality and purpose in fax transmission.
