I now have an OpenVox A400P and it is working well. Thanks to Ade<br>
Vickers for the recommendation, which I second.<br>
<br>
However, I need to make a slow transition between a conventional<br>
multiple-extension setup and a full VoIP network on these premises. So<br>
at the moment the Asterisk box shares the PSTN connection with several<br>
conventional analogue handsets.<br>
<br>
The desired result for an incoming call is that the Asterisk server will<br>
wait N seconds before answering (which I can arrange easily enough), and<br>
if the call has been answered on one of the handsets by that time the<br>
Asterisk server should ignore it completely. Otherwise it should start<br>
checking CLID, prompting for extensions, and other good stuff, which<br>
again I know how to do.<br>
<br>
What is a good approach to making sure the Asterisk server doesn't pick<br>
up a call that has been answered elsewhere? (Ideally in pure dialplan,<br>
but a perl AGI would also do.)<br>
