Hi Support:
With SingleLine Phone example within latest image v6.0.0.3, DTMF does not work with IVR server even though setting related to DTMF is correct(Both/Simultaneous). Pls try the following server for troubleshooting.

IVR Server: sw2.sp.ring-fone.com Port: 6060
user: 77880002 password: 785236

Pls dial 1008 or 1006 directly for accessing IVR(G.729). When hearing voice prompt, press 4 for english information.

Thanks,

Which single line phone sample app did you use – the managed code version or the native code version?

Using v6.0.0.3 media engine with another softphone app here and accessing your server using works good using RFC2833 DTMF signaling. Your server however does not seem to respond to in-band DTMF signaling.

Its probably a bug in the sample source code. If you tell us which single line phone sample you used, we will check further.

Hi support:
Sample used for test is native code version. I think there exists a bug in handling DTMF within example code. Pls fix it to allow me test again.


Thanks

Hi George,

Hmmm… something must have changed in your sample source code maybe???


I just performed the following test:

1)
Installed V6.0.0.3 on a development machine here in the lab.

2)
Started the native code single line soft phone.

3)
Configured the phone settings for the sw2 server at your location.

4)
Set the phone line codec to G729.

5)
Set the DTMF type for all codecs to be “Both” and then selected all the checkboxes for “Simultaneous DTMF and audio output”.

6)
Made a test call to extension 1008 and played around with the DTMF menus (once I got it to change from Chinese prompts to English by pressing DTMF keypad 2).

All seems to be ok. Is there some change in your code that is causing the issue?

Here is the SIP log for the test call:

Hi Support:
Very pity I don't get same testing result as u with SingleLine Phone example. Frankly speaking, no any modification to existing example source code with v6.0.0.3 product image. So in order to clarify root cause of IVR access issue, can u mail me your used full example source code?

It is urgent issue which must be resolved and I am pushed very much.

Hi George,

Please do not take offense, but these problems you are having are a bit ridiculous. Maybe your group should consider entering into a short term paid support agreement with us so that we can assist you with a higher level of support instead of this free support forum stuff. If your VOIP project is important to you and you are rushed for time, the free support we offer may not be adequate for you. If you obtain paid support from us, I will personally hold your hand to get you the results you need. If that’s what it takes - Not a problem.

It is rare that a customer struggles as much as you have struggled. It is not good for you and it is not good for us.

I just submitted this post to the forum in answer to another question you had:

Why My Normal license NOT Work?
http://www.lanscapecorp.com/forum/forum_posts.asp?TID=555&PN =1

...and all the issues you are reporting we cannot reproduce. Maybe we are having a language communication issue or something similar. Have you read any of the VOIP Media Engine documentation or at least looked at the Software Developer’s Reference on how to use the media engine? Hmm……..

Your product image and the sample source code for the v6.0.0.3 product you have and the “single line phone” native app is ok. Your problems lie elsewhere.


Thanks,

Randal
