Summary:                    [patch] [regression] T.38 no longer functions
Description: 
After upgrade from 1.6.11 to 1.6.1.12 T.38 no longer functions.

WARNING[26670] udptl.c: (SIP/4065877430): UDPTL asked to send 1 bytes of
IFP when far end only prepared to accept 0 bytes; data loss will occur.You
may need to override the T38FaxMaxDatagram value for this endpoint in the
channel driver configuration.

This is generated even though sip.conf has
t38pt_udptl=yes,redundancy,maxdatagram=176

After returning to 1.6.1.11 T.38 functions correctly.
