Summary:                    [patch] [regression] T.38 negotiation Broken
Description: 
After upgrading from 1.4.26.3 to 1.4.29 the T.38 negoation seems broken.
Probably this issue is a replication of 0016318 . Unfortunatly on the
1.4.29 it's look like the issue it's not totally fixed. 
I try to send a fax from an ATA to a fan on analog line.
ATA -> Asterisk -> Patton SN4091

When the fax answer the asterisk don't handle properly the call, on the
CLI I can see the message "Start music on hold" link with the ATA sip
channel.

As attachment the log of the console
