I place SIP DID call towards ZAP (TE410P). ZAP uses e&m signaling to an external IVR system. I can hear the asterisk sending the DTMFs properly toward ZAP at call setup. After the call connects, any further DTMF digits from SIP is very short sounding or distorted (barely audible) on the ZAP and ignored. ZAP to ZAP connections work perfect. Just so you know, with 1.2 this is not an issue and this issue is keeping me from moving to 1.4. I have a test system setup with a SIP DID to a test IVR system to demonstrate this problem. I can provide full access to these systems for testing. I've placed on Digium bugs but have not received any responses yet. There is nothing in the logs or cli that provides anything meaningful - Below is a call where I press '' and it is ignored.

Steve, I fooled with dtmf mode and it was 2833 - However, got stranger
results with inband, seems it would take digits, but audio goes to 1 way
afterwards first push.

As far as changing the code per the URL, I think I get what's it doing, but
wonder what else would be effected afterwards - I guess I could switch back
if it turns out to be a bad idea

Bart,

Did you try the method of inband along with changing the frequencies
at the same time?

Thanks,
Steve T

Hello, here are a few pointers that might help. Are you using
RFC2833, inband, info? My guess is 2833, you might want to give
inband a try unless you are using a lossy codec.

This is pretty interesting and might solve your issue. It seems that
by doing this, Asterisk just passes the DTMF as regular audio instead
of trying to interpret it. Bookmarked for when I run into this same
issue.....

Linked from this page on the wiki that has more info on your issue.

Also, when you tried inband, did you set it on the phone as well as sip.conf?

Thanks,

Yep - tried both and combination thereof - The bad effect of inband mode was
audio went one way after first press
My test app reads back the ANI & DNIS at answer (which works), then prompts
for more digits.
It's suppose to read back whatever is heard. I can see it reading back
something, back I don't hear anything.

One note: if I press say '1111111' fast, it might hear '11', but not all
digits sadly
I'm sure this is a 'bug' as it work perfectly on 1.2, but so far there is no
acknowledgement from Developers yet.
Not sure how long it should take Sad

Yeah, it gets a bit confusing with all the scenario possible - Regardless,
you are right I should stay on 1.2 until 1.4 is ready for prime time, but
now that 1.6 is out, I'm sure I'm in for a long wait. I reposted my bug
again, since I think I may have listed it wrong - it's now
http://bugs.digium.com/view.php?id=12913 - Maybe now someone might notice Smile

Thanks, Steve for your inputs

Bart
Asterisk has never been good at catching DTMF in rapid succession. I
have read in many places that asterisk 1.4 had many changes to DTMF.

You contradict yourself below. "The bad effect of inband mode was

Quote:

'1111111' fast, it might hear '11', but not all digits sadly"

I suppose that you were using different methods. Try pressing the
keys a little slower.

Personally, I would just go back to 1.2.X if you cannot get anyone to
acknowledge your issue. What features do you need in 1.4 anyways?
Maybe if the DTMF bugs you opened get resolved then 1.4.X could be
revisited.

Thanks,
Steve T
