- * Asterisk supports T.38 fax passthrough. Asterisk will not be a client, server
- * or any form of gateway. Currently fax passthrough is only implemented in the
- * SIP channel for strict SIP to SIP calls. If you are using chan_local or chan_agent
- * as a proxy channel, T.38 passthrough will not work.
+ * Asterisk supports T.38 fax passthrough, origination and termination. It does
+ * not support gateway operation. The only channel driver that supports T.38 at
+ * this time is chan_sip.
*
* UDPTL is handled very much like RTP. It can be reinvited to go directly between
* the endpoints, without involving Asterisk in the media stream.
