Looking for a modem

Looking for a modem

Looking for a modem

Does anyone make a modem that can do all of the regular modem functions as well as generate the voltage for a ring signal to any telephones that are directly connected to it?

Basically, I want the modem to intercept incoming phone calls, and then be able to go ahead and ring the connected phone(s) if the call meets certain criteria.



RE: Looking for a modem

 Don't know of a modem for this, but consider a fax switch called 'the Stick'. It has two programmable ports and a no tones voice transfer default. It is reliable, remote programmable and not too expensive.


RE: Looking for a modem

Thanks for the quick replies.

I did'nt see anything on those items that would do what I needed.  Let me be a bit more descriptive.

I want to write a program that has certain features.

What I want to do, is have the modem pick up any incoming calls without ringing the phone.

All callers will have to do one of two things:

1:  Speak their name and voice recognition will automatically connect them if they are in the program daatabase.

2:  Enter a PIN to be connected.

Users that can do neither will be directed to a voice mailbox.

Validated users will be connected, if the mode is set for that particular user to be connected.  For example, I might set the mode to one where only a particular person gets through, but all others go into voice mail.

If the unit is in away mode ( I'm not around ) then the user is directed to a voice mail.

Each caller can have a custom message for them that will play, so for example, if my boss called, he would get one message, while my best friend would get a different message.

And so on and so forth.  I've got a longer list of things I want it to do ( Caller ID, forwarding, paging, e-mail, etc ), but the basic problem that I come back to is that it needs to be able to ring the phone that is connected to the PC, and connect the incoming call to it, after it has done all of it's validations and so forth.

Of course, I can turn off the ringer on the phone and have the program play a sound over the PC speakers instead, but that only works if I happen to be in hearing range of the PC.  I don't want to have special speakers all over the place in my house....



RE: Looking for a modem

 Hm. In your house. I guess that means you don't have a large office telecom infrastructure to build on? So Okay.
Try looking at some of the Voice/Fax/Data programs that come with communications suites and modems. An old one that comes to mind is the Hayes SmartComm. I'm not sure that Symantec's TalkWorks will do all but look there. When you get right down to multiple choice of data/CLID/Voice recognition/fax switching/ all on single line devices such as modems, you need to go to the computer equipment providers. Most of the Telecom devices that I am aware of in this area are big bucks and would generally be inapropriate for home installation.
 I'ld be interested to know how this all turns out for you.


RE: Looking for a modem

The Talkworks from Symantec was discontinued. I looked into a few months ago for an application of a customer.
It sounds like you want all the bells and whistles of an IVR.
Check out DIALOGIC, they have cards that fit into what you are doing. Pricey for home, but i did it for my house!

what language are you writing your program in?

RE: Looking for a modem

Thanks for the replys.  I'm looking at the DIALOGIC page to see if they have what I need.

The program would be written in VB6.

I'll let you know how it turns out.

Thanks again,


RE: Looking for a modem


There are a whole load of professional voice cards out there,

IMHO Dialogic are good, but one of the more expensive...
Try Brooke-trout, they are much cheaper.  Music Telecom and Natural Microsystems.

You might look on ebay or google for some sh ones though.  You also need to ensure that the card you choose will support both trunk lines (for your CO) and station lines along with ring voltage.

However, VB6 may not be the best choice for this sort of stuff...

The SDKs are aimed at C or C++ developers, you will need to be very adept adapting HPP headers in to VB

Let me know how you get on

Take Care

If at first you don't succeed, skydiving is not for you.

RE: Looking for a modem

Thank's for the suggestions Matt.

I realize that I'm in for some work getting the SDK's to interface with VB6, but I enjoy a challange :)

If I can offer any help..

RE: Looking for a modem

We've had good luck in the small-office environment with some of the Com-Switch line.

They have models that support dial-through, CNG recognition, etc.

Another way to do it, in a slightly more up-scale environment is with AA and FAX/CNG built in to some VM systems.  Of course, that assumes there's a phone system that's VM/AA equipped, with CNG/modem handshake recognition.

RE: Looking for a modem

Hey Vamp,

One of the post mentioned Natural Microsystems and Brooktrout. Both are good products, cheaper than Dialogic, come in 2,4 and 8 port increments and can be found on the refurb market.

Try AMDEV for refurb products and you may want to check out Pronexus for some VB ideas. Pronexus is a Canadian company specializing in IVR installations and have some really cool toolkits available on their site, of course they are intended for the end user to customize/modify their own installed base but you may find some good tools and ideas.

Best of Luck.

RE: Looking for a modem

Thanks for the suggestions!

As it is, the modem project has been moved to the back burner, as I have taken on an assignment of writing a program for a friend, to interface his home PC over his VPN with the alarm system at his business.

Thanks again,
