I have a problem with my Voice Gtaeway 1760 concerning fax issue!!
I think that the problem is that the Gateway is unable to change the codec from G711ulaw to T.38 !! and i don't know why!
My test is simple: i call the number via PSTN and i expect that tone change to modem but i don't hear that, and when i use the command "sh voice call status" i can see the call but the codec is G711 and i doesn't change to t.38!!
could the problem be because of DSP?
PlZ help me it's really urgent.
Thank in advance
