The chat50 is very flexible, like Phoenix Duet - can connect to landline or cellphone (earpiece jack). It doesn't seem that chat150 can, at least out of the box. Can I adapt it to work with POTS and cellphones? The Chat50 is just too small/weak for my application - 6-10 person conferences around tables, typical distance to the box is about 7' for each participant, some up to 10'.
Please advise .. would like to make this work.
I didn't find the right solution from the internet.
