Jeff, thanks for your answer!
I helped me to correct the code, but looks like the sending fax error is not related to it.
1)The RX_CODING setting error has gone - it appears not to accept DF_JPEG_COLOR value and this fact was mentioned in the doc. Looks like the RX_CODING value is not required with color faxes. For clear testing the last files were b/w tiffs.
2)G.711 fax is sent and received properly (rtflog.G711.zip is in the attached rtflog.zip). However there is an ipmB1C1 error though it affects nothing.
3)T.38 fax is not sent with the same fax settings and the same tiff file (rtflog.T.38.zip is zipped in attached rtflog.zip). Aside from ipmB1C1 error I found there a "CheckTiffFileIntegrity" error and it's weird cause there is no such error in G.711 fax session.
