Please contact Digium technical support.


I noticed that the latest wct4xxp sources allow disabling DTMF support
in VPM modules.


There are other steps that can be taken if necessary first.

It just disables the VPM's capability to detect DTMF; DTMF detection still 
works within Asterisk as it'll be done on the host CPU (i.e. the old way 
before the TE406).  

 Will it help me in this situation and if disabled, will I still be able
 to call IVR systems from my PABX?

Yes, it clears this up very well, at least in my experience.

Can you please elaborate on this? It may just save a lot of calls to Digium 
support about the same issue. (I have noticed this sporadically).

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.

 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!
