I have connected my home phone line into my asterisk box via an X100P, but have noticed that asterisk doesn't check the line for dialtone before dialing, barging in on any non-asterisk call which is taking place. I see from the voip-info.org wishlist that there is an outstanding item to 'Listen for dial tone before dialing' and I also see someone suggesting a solution for the problem by adding additional hardware into the home phone circuit. I'm just wondering if anyone can recommend another (perhaps zapata.conf-based) fix. Thanks, Malcolm -------------- next part -------------- An HTML attachment was scrubbed...

Also optionally listen for stutter dialtone before dialing, making the detection of stutter dialtone available for some other action. Certainly these days even simple key/hybrid PBX switches monitor the DC status before allowing access to a line. John Novack -------------- next part -------------- An HTML attachment was scrubbed...
