My recommendation would be to stay away from VoIP even T.38 whenever possible.
That said yout best option is to use TDM, for that you can either use
1 single span T/E1 from digium and an analog TDM card for FXS.
Or you could uee a dual span T/E1 card and a channel bank with FXS
ports. While the later is more expensive I prefer that, since it gives
lots more options in the long run.
