It's not quite like auto-dialing via a 1200kbd by sending AT... commands to PC modem on COM1 20 years ago and then picking up the handset?
Not even close.
I mean, can I make a call on the headset/x-lite and then put it on hold and forward it to ring the phone on the OBi110, perhaps using speed dials?
It's only possible to make and receive calls when using OBiON Apps and X-Lite/OBiAPP for PC.
And, it would be nice to be able to transfer a call to the house phone -- or from the phone to the OBiAPP/x-lite
Calls can be transferred from the OBi PHONE Port to OBiON Apps and X-Lite/OBiAPP for PC Using Blind Transfer
