[Freeswitch-users] Problem with T.38 fax receive using ESL

[Michael Collins]

I don't see any indication in the docs that this syntax is doing what you
think it is:
{fax_enable_t38_request=true,fax_enable_t38=true,fax_header=testheader,fax_ident=testident}/tmp/faxes/myfax.tif

You could confirm this by removing the two "set" apps and adding those to
the "rxfax" call in the dialplan:
<action application="rxfax"
data="{fax_enable_t38_request=true,fax_enable_t38=true,fax_header=testheader,fax_ident=testident}/tmp/faxes/FAX-${uuid}.tif"/>

My guess is that the above will not work. I would recommend trying the
SendMsg to set the vars:

SendMsg 5716720c-e291-11df-939c-75e5ad3b2de7
call-command: execute
execute-app-name: set
execute-app-arg: fax_enable_t38_request=true

Do that for each var and then do the rxfax. Let us know what happens.
