[asterisk-dev] [Asterisk] Applications/app_fax asterisk, t.30-t.38 gateway

[Pavel Selivanov]

Hello,

Can anybody point the working patch/configuration for t.38-t.30 gateway ?
https://issues.asterisk.org/view.php?id=13405
I've tested asterisk-1.8.3_2_fax.patch 
<https://issues.asterisk.org/file_download.php?file_id=28874&type=bug> & 
asterisk-1.8.4_fax.patch 
<https://issues.asterisk.org/file_download.php?file_id=28947&type=bug>:
t.38-t.38 - OK
t.30-t.30 - OK
t.38 & t.30 termination/origination - OK
t.38-t.30 gateway - don't work

gateway test: t.38(SendFax) - T.38-T.30
on t.38(SendFax) side, I've got
[Apr  4 00:27:05] WARNING[4945]: res_fax.c:2025 sendfax_t38_init: Audio 
FAX not allowed on channel 'SIP/topavel-00000001' and T.38 negotiation 
failed; aborting.

If I enable alaw and enable "fall to audio mode in Dial" - all is fine.
