If I configure none then no ec will be accepted.
If I configure redundancy then redundancy OR fec will be accepted.
If I configure fec then fec OR redundancy will be accepted.
The actual behavior of the option needs to be more completely specified.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">By default, if t38 is enabled then the error correction mode will be set to FEC. Optionally, if t38pt_udptl is set to 'yes,none', then it will be set to use no error correction. However, currently if Asterisk receives an invite with error correction in it for a peer with error correction disabled, it will include the offered error correction in outgoing invites.
This patch was written and tested by Nitesh Bansal. It adds some error correction mode checking while processing the SDP and if an image header is detected in SDP for a peer that hasn't enabled T38 yet with an error correction scheme of none, then the error correction scheme will explicitly be set to none for the SIP private's UDPTL session.</pre>
