Hi,
we are trying to move DTMF functionality from single line phone example app to the multiline phoneexample app, but the following error occurs while the multiline app is running, no compiling error.
//
error detected while creating DTMF generator
//
it happens when:
DtmfGenerator = CreateDtmfGenerator(m_hWnd,DtmfGeneratorCallback,this); is excuted.
we just copied those code from singline phone to the multiline phone, and we could not find any reference of the dtmf in the development doc, so could you please give a hand to figure out what the cause could be?
regards,
will

Hi Will,
Thank you for posting this question.
The DTMF and spectrum analyzer static libraries that ship with the VOIP Media Engine example applications are designed to only work with the software examples as supplied by LanScape.
The DTMF library will only function with the single line phone and Dual line IVR server example applications. That’s it. You will not be able to use the DTMF library in your own application and in any of the other software examples. The same is true for the spectrum analyzer static library.
This is by design. We are in the process of completing the development of several VOIP telephony libraries that will be useful to you and other customers. The actual date they will be released is not yet decided. We assume it will be sometime in 2005.
We are not able to allow the static libraries that ship with the examples to be used due to the fact that they are part of an upcoming product that will be marketed and sold on its own merits.
If you want to include DTMF generation and detection in the VOIP application you are developing, you have a few choices: purchase another vendor’s DTMF library, purchase a “Pre-Release” copy of LanScape’s DTMF library and tuning tools, or wait until we officially release the DTMF VOIP package.
We understand the need for real-time DTMF capability and are working hard to offer this capability to all of our customers. It will be available shortly.
Best regards,
LanScape Support

Hi, thanks to your reply,
so the questions pop up :
1.How much is the “Pre-Release” copy of LanScape’s DTMF library and tuning tools?
2. How is the existing DTMF library bound with the singline phone, is it possible to by pass the constraint technically in the code for a shor amount of time in order to just show it works with the multiline phone?
regards,
will
