[asterisk-users] FXO Cards - T38

[Fernando Berretta]

Dear All,

Are you telling me Asterisk 1.6.0b2/4 has support for t38 and rxfax etc. 
and will be able to receive faxes and negotiate with voip CPE's like 
ATA's to transmit faxes which comes from FXO cards to VoIP Devices using 
T38 ? it is possible to compile this version of app_fax to work with 
Asterisk 1.4x ? Someone has tried it ?

Best Regards,
Fernando
