[Freeswitch-users] unable to make outbound fax

Hi, I've got problem with outbound fax, the fax machine is connected to FS server via ATA device in a pass through mode, inbound fax works fine, but could get outbound fax to work, here is the dialplan for it, do I miss any parameters? What's wrong with the dialplan? Fax_A (4919)->ATA_A->SIP->FreeSWITCH->SIP provider->PSTN->Fax B <extension name="t38_passthru"> <condition field="destination_number" expression="^61000$"> <action application="export" data="t38_passthru=true"/> <action application="bridge" data="{sip_invite_domain=$${domain}}user/${dialed_extension}@${domain_name}" /> </condition> </extension> Cheers, Louie
