[cisco-voip] isdn incoming-voice modem or voice

[Mustafa Yadav]

Hi


Can someone explain what are the differences between isdn
incoming-voice modem and isdn incoming-voice  voice?

We had a problem wtih T37 onramp fax gatewat.Some times we get
corrupted fax pages after changing isdn-incoming-voice voice to modem
and adding   isdn overlap-receiving T302 2000  command it has started
to work fine?
What do you think the problem is ?

Many thanks
