That's exactly how they explained it works. The DTMF is only to provide
DNIS and using the register signalling. When I run testcall, I get the
handshake but when testcall sends the first digit, the remote equipment
doesn't recognize it (because it's expecting a DTMF signal) and then it
times out. I don't want to buy the Cisco for this :( especially when I
wanted it to be a full open source solution. What would it take for you
to implement it? <br><br><div><span class="gmail_quote">2005/11/10, Julio Arruda <<a href="mailto:jarruda-asterisk@jarruda.com">jarruda-asterisk@jarruda.com</a>>:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
