[Freeswitch-dev] Using a modem to connect ordinary phones

[Alex To]

Thank you very much for your prompt reply Mike

 

The problem is I could simply get everything working by buying a zaptel
compatible card or a VoIP Gateway. However I would like to use the modem
that I am developing since it does provides some additional features. 

 

Does that mean I could start my way reading about Zaptel and develop a
modified version of Zaptel to control my modem ?

 

Thanks for pointing me the way.

 

Regards

 

Alex To

You are better off creating a zaptel driver than re-creating all that work
that has already been done.

Hi,

 

I found the same topic created 2 years back in Oct 2007 but it doesn't seem
to have the answer yet.

 

 I am quite new to FS and having a hard time reading the documentation.
Someone could tell me: how would I use a modem and develop an Endpoint in FS
that I could bridge the call from VoIP to PSTN. I am a hardware engineer, I
am developing this modem and would want to use it with FS. I know that I
could simply buy a VoIP Gateway or a zaptel compatible card and use OpenZap.

 

Could someone point me out the direction for the following matters:

 

1.       I feel that I need to develop an Endpoint module, like mod_sofia,
mod_iax... that controls my modem so I could bridge the call from VoIP to
PSTN ? If that is correct, could someone point me the documentation to start
reading about Endpoint interface .?

2.       Is there any similar module developed before about controlling a
modem using AT Command
