I have an asp.net web page with a “dial” button; when the user presses the button, it connects the user to the PTSN network to make a phone call. This is for outbound calling only so there’s no need to worry about incoming calls.
I’m thinking of using a webphone and finding a VOIP wholesale provider. Ideally, I’d like the server that’s hosting the web app to not be involved in this process (ie. the webphone connects directly to the VOIP provider).
What are some of the pitfalls to avoid?
Thanks for your suggestions.
There are a few Flash based softphones around you could use. I’d recommend taking a look at Phono from Tropo. It’s designed for initiating calls via javascript in the browser. I think it does or will use HTML5 where available but falls back to Flash for some parts.
