Hi, my client has UC320W. the office has 3 FXO lines.
they are claiming that they can't make outbound calls on 1, 2 FXO lines (inbound calls are fine).
it just drops after dial the numbers.
however 3rd line has no problem to dial out.
one weird thing.
I setup to dial 9 to make outbound calls.
3rd line, which works fine, doesnt need to dial 9 to call out.
you can just dial 1xxx-xxx-xxxx.
the other 2 lines wont work 9xxx-xxx-xxxx nor 1xxx-xxx-xxxx
it just drops.
