[asterisk-users] TE2XXP and modems

[Steve Totaro]

Have you tried faxing and modems directly through the Alcatel?  If it
works well, then I would not expect too much of an issue.

The main issue with faxing and modems are latency and lossy codecs.
TDM with alaw/ulaw end to end "should" be OK.

Thanks,
Steve Totaro
