Hi

I am looking for a component that can be integrated to a VB.NET program that
can dial a number using a normal telephone line, record the conversation and
allows saving of the content so it can be played later

Thank you for your advice

You need a voice modem to do recording via a modem.

Otherwise you could use the line-in of the soundcard and a telephone -->
minijack adapter (available at radioshack etc.).

If you're doing this via VoIP there are other options available.

Voice modems are typically a poor choice for this sort of application.
If using VoIP, as Spam Catcher said, there are other options, but if
you just need to dial a number and then record a conversation then you
be better service by getting a dedicated telephony board. These boards
have features to monitor call progress and can record as well as play
audio over the line. They are specifically made for telephony
applications. And while these boards used to be fairly expensive,
nowadays you can get a two line card for no more than $125 and probably
find one used for less. Do a search for Dialogic on EBay and you will
find lots of hits. And there are some SDK available for these that can
be used in VB or C# or VB.Net.
