Hi All,<br><br>I have a telephony project for which I need <br>to build a prototype to demo for management.<br>The prototype must work on a GSM phone network.<br><br>In the demo system, a call from GSM phone comes<br>into the demo box. The demo box runs CallWeaver.
<br>Callweaver picks up the GSM call, answers it and<br>plays a sould file, then dials out to a second GSM<br>phone somewhere and connects them so they talk.<br><br>My question are these:<br><br>1. Is this a job for Callweaver/asterisk system?
<br><br>2. if not, what package out there would handle this?<br><br>I was reading the Asterisk doc and it mentions that<br>a modem could be used with an Asterisk system, but <br>does not show how it can be configured to function in
<br>the system. Does anyone here know how?</blockquote><div><br>There are various PCI and Ethernet GSM interfaces that should work with Asterisk. These would be your best choice in terms of reliability and performance for a production system. It wouldn't hurt to have a fixed, semi-directional, antenna pointed to the tower either.
<br><br>I wouldn't recommend for a production system, but you can also use a GSM -> Analog adapter such as the "CellDock" or "DockNTalk" I think some people call this "Tellular" and also somewhere is chan_bluetooth which allows you to place calls through a bluetooth mobile.
