Be absolutely sure you have your Zaptel/DAHDI timing settings correct so all ports are sync'ed properly with one timing source. Also, ensure your telco is giving you a real TDM circuit/path, not a TDM port that is serviced by a VoIP connection. Many companies are doing this now as it cuts their costs significantly for service delivery and works fine for voice but you'll have problems galore trying to get a modem/fax carrier working reliably. They'll usually call this product a 'flex T1' or 'Mega T1' or some other marketing-hype type name and give it a lower cost. You don't want to walk away from these products, but rather, run as fast as you can. :-) I've used the Rhino channel banks extensively and they work very well. In fact, a recent installation was specifically for combined voice/fax/modem usage and it performed perfectly. The only difference in my case versus yours was that the T1 was being provided by the telco, not via a T1 card in another Asterisk box. But again, assuming you have your timing setup correctly, this should work very well. --Tim
