[Serusers] t.38 fax woes

HI,
WE are having problems with t.38 fax and record-route in SER.
Without record_route, using only t_relay(), fax works fine between two
of our UA's.
However, when record_route is used, a voice call is successful but a fax
call fails. An ethereal sniff shows that the "re-invite" from the
destination to the origination is never forwarded to the origination
UA. Thus, the fax fails.
If I turn off record_route(), the fax call succeeds.
An ethereal sniff of the failure case is attached. A snip of the ser.cfg
file which shows the use of record_route() and t_relay() is attached.
If I comment out the one line for record_route(), the fax succeeds.
Any ideas as to why this fails?
thanks
bert
