I'm looking for hardware recommendations as far as a FXO card is concerned (have used the TDM400 in the past, but would like to save money if possible). My applications utilize all VoIP(SIP) but require a timer for meetme conferences. We're currently using ztdummy for testing, but would like a hardware timer for production. There is no need for FXO/FXS ports as we will not be plugging into a PSTN.
