Summary:                    SendFax does not work probably as it keeps sending
INVITES
Description: 
Hi,

i'm trying to setup SendFax (ReceiveFax is working fine) but when the
other side initiates T.38 Asterisk keeps sending INVITES instead of
accepting T.38.

---------------------------------------------------------------------- 
I suspect this is caused because chan_sip responds to the remote host's
T.38 request with the m=audio SDP block first then the m=image block, but
the request had the m=image first and m=audio second.  IIRC each m= in the
response should correspond to an m= in the request (i.e. they should be in
the same order).
