The first and most important advice would be to actually include 
information that would allow people to help you. For example, 'sip show 
peer' output confirming that *both* SIP endpoints have T.38 enabled. 
Then, a complete 'sip set debug on', 'core set verbose 10' and 'core set 
debug 10' console capture of a failing call, so that we can see what 
happened with the T.38 session setup attempt.
