Incomming DTMF not working

[Mori]

As said before.

Inncomming calls from internet->cablemodem->router with all ports open->win 2k3 server sp2 (IIS and PHP installed) witch also hosts 3CX.
Nothing in between here that should inflict with the calls.

Where can i set the DTMF sample rate then?
Havent seen any places in 3CX console where i can specify that rate?

Hi again.

I finally got a response from provider, and they use rfc2833 for DTMF.

But if im not mistaken the 3CX should accept that?

Aslong as you using the correct codecs than it should work ok.

Obviously you cannot chang the DTMF frequency so we have to try something else.

I have the feeling that your callers do not press the buttons long enough for your system to figure out what number was pressed (or key).

So can you tell me if you can configure:

DTMF Playback Level and the DTMF Playback Length ? also the Detect ABCD ?

 

[Mori]

My callers (that would be me testing this out) do hold the keys long enough...

Two of my friends have tried out calling from there GSM phones, and both attempts failed.
Both tried calling from there VoIP phones, and one failed, but the other was a success. They have diferent providers.

About

DTMF Playback Level and the DTMF Playback Length ? also the Detect ABCD ?

Where do i set these parameters?
I have no other place to change them for incomming calls than in 3CX console.

For your notice, all outgoing calls using DTMF (eg phonebank) works great.

Should be on your ATA or if you do not have one you have no way of change it.

Make sure you use the correct codecs G711. have the gateway bound to a mediaserver etc.


If all fails it might be the voice provider
