As has been noted several times, attempts to use modems over voip connections will be less then reliable, incluidng the tdm card. Part of the reason is the type of modulation used with some modems and part of it relates to tdm issues moving data across the pci bus (and/or interrupt latency). The slower the modem, the more likely you can get something to work. The tdm (and associated drivers) do not check for dialtone before dialing. _______________________________________________ --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
