[Ahmed_ElMahdy]

Hello ,

SPA122 connected to the FAX machine , when I dial the VOIP no. I am getting the FAX tone but when dialing from the FAX machine any other FAX no. there is beep sound and then nothing ... Normal calls are working fine incoming and outgoing but the outgoing FAX is not working .

T.38 configuration followed .
