Hi, I'm getting a lot of false DTMF detections on my system. Following is a diagram of my system: PRI<->TE406P SPAN1<->TE406P SPAN3<->PABX Basically anyone talking to me with a higher pitch voice (Ladies) I get "beeps" all over the place. If I unplug PRI from Asterisk and plug it directly to PABX I do not get any "beeps" during conversation. I noticed that the latest wct4xxp sources allow disabling DTMF support in VPM modules. Will it help me in this situation and if disabled, will I still be able to call IVR systems from my PABX? Thanks in advance! -------------- next part -------------- An HTML attachment was scrubbed...

We disabled it in the wct4xxp.c driver as well and everything has worked great since then. I have heard from support to try raising the threshold value while leaving hardware DTMF detection on and it didn't help raising it by 100. In the big picture, doing hardware DTMF detection gives you an incredibly small performance boost so you really won't notice any load difference if you disable it.
