I'd like to know which Obihai product to consider for cordless phones in a house. I'd like to have up to 10 handsets. I'd also like to be able to handle answering calls for up 2-4 cell phones. I only need one POTS line.
I don't envision more than the cell phones and POTS line being active for calls at one time (as in, I don't need all 10 handsets to be able to make SIP calls at the same time).
I do need the ability to share a call across handsets, like to let the kids all talk to Grandma at the same time.
I do like the idea of each handset being an extension, not just a 'party line' setup like typical cordless phones. I'm fine with this possibly requiring 'dial 9' and the like to get an outside line.
What's the right way to approach this?
