Using a UC520 and wondering if I can get the following to work:
1.) CallerID from the second call in the FXO line (Callwaiting) show CallerID.
I hear the callwaiting beep that I am assuming is inband from the FXO line. I can use hookflash on the CME phone to pick up the second call coming in, but I don't get CallerID. If I plug an analog phone directly into the line, I can get CallWaiting CallerID.
2.) Conference calls to hookflash outbound on the single line to use the analog PSTN line's three-way feature.
3.) CallWaiting/Hookflash functionality to accept second call coming in FXO line. If I place an outbound call from an analog phone on the UC520 (FXS), I don't seem to be able to pick up a callwaiting call that comes in on the FXO line from my analog phone.
Thanks all! Here's to trying to make a UC520 really work for my house!!
