Hello
I have a 20 years old machine using a phone voice over VOIP on ATA122 working fine but can´t send a MULTITONE signal (DMT) over the ATA so can´t work 100%. I tried G.711 some fax or modem option but nothing. ¿could you please help me?
This test are made on LAN(ATA) conected with internal PBX line so, there isn´t noise or disruption in line. sound are perfet.
Thanks in advance and regards.
