<br>An exclusion adapter is overkill. My Asterisk line card is the $10 Win modem card that I got from ebay.<br><br>When you call my copper line, two devices see the inbound ringer:<br><br>1. The Uniden 5.8Ghz cordless phone base station that answers 95% of the calls<br>
2. Asterisk with a win modem line card that: a. runs a perl AGI script to parse caller-id name and number b. rings a sip extension or c. answers the call and plays funny messages and DTMF tones at the telemarketers.<br><br>
Just make sure that Asterisk only RINGS the sip extensions but never sends the call to play a message or voicemail or any other Asterisk feature that will issue an implicit Answer and take the call.<br><br><br><br>
