Here’s how my setup is. I have a standard Asterisk install on my Debian box, using Teliax. I have the LinkSys Sipura 3000 VoIP adapter hooked to my POTS internal house line. That’s pretty much it, and everything works wonderfully. With Teliax, we get 3 channels, so if someone is on the phone, and Asterisk receives another call, it rings for the caller and they hit voicemail. I have no problem with this, but how can I make the phone beep like a “standard” telephone system would (where I would hit flash and switch to the other call).
Any tips? Thanks
