Hi I just want to note some technical points here:

Some technical notes: the echo won't be a problem with faxes (bad echo cancelling may be). It is a problem for voice calls, indeed, and nees cancelling there. With faxes the problem is syncing between different zaptel devices. That is: a fax sent between an FXS posrt and an FXO port of a TDM400P card or between different ports of an Astribank FXS/FXO unit will get through. Faxes from a T1/E1 card to a fax on an analog port will have sync problems. > > Xorcom are supposed to be working on the echo issue, but the last drivers > they supplied us didn't fix it completely, and we haven't heard from them > in months about versions with better echo cancel. Again, please separate the faxes and the echo issues. We have done some work on the echo issue, and the result is already in our latest drivers. If you have any echo issues, please let us know so we could resove them. As for the issue of the fax: I'll keep you posted when we have something working. -- Tzafrir Cohen sip:[EMAIL PROTECTED] icq#16849755 iax:[EMAIL PROTECTED] +972-50-7952406 jabber:[EMAIL PROTECTED] [EMAIL PROTECTED] http://www.xorcom.com _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
