|
||||
*
|
||||
* 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.
|
||||
*
|
||||
* UDPTL is handled very much like RTP. It can be reinvited to go directly between
|
||||
* the endpoints, without involving Asterisk in the media stream.
