Better test it before making any commitments. The credit card reader will be using a modem, and modem transmissions throught the TDM card have been problematic for a large percentage of those using it. There are a very large number of potential show-stoppers with it, and the majority seem to be system dependent. Therefore comments from others will be almost useless in terms of ensuring an operational system. Having worked with several relative to TDM problems, I'd have to guess that somewhere near 90% of the implementations won't handle fax/modem calls. However, I have no idea whether those problems will impact the slower-speed credit card reader modem use. If it doesn't work, a reasonable alternative might be to use an spa-1000 (or the equivalent), but that would need to be tested as well. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
