Friday and Saturday I was wrestling with a VoIP system that was having very strange problems. It was playing the outgoing IVR audio at 2-5x faster than it should have been. I found that if I stopped asterisk, removed the wcfxs driver and installed the ztdummy driver, the audio would play fine. I tested this in and out several times and it always worked fine with ztdummy and never worked right with wcfxs. I cannot find any references on the 'net about such a problem. Anyone else run into this? Details: Asterisk 1.0.6 MSI K8T Master2 motherboard Single AMD Opteron installed on the motherboard (other socket empty) TDM card with a single FXO installed on it The system is working fine now (SIP in and out), but I want to put a PSTN line into the FXO port as a land-line fallback. I also figured the TDM card could be the timing device for meetme and such, but I think ztdummy will do just as well there. Anyone else run into this?
