hi heather,my wiring is connected thur my land.i want to put the person i'm talking with on my landline on hold while i see who is on the intercom at front door(i'm in an apartment)then letting them in,then return to the person i have on hold.
I kind of answered this in your orginal thread, but that depends on the building's intercom system, what it does with the current call, hangs it up, or lets it continue
I'm going to lock this thread just to keep things neat and tidy. Kevinds and I will respond here https://community.shaw.ca/thread/8698
