Voice call gets cut off even ringing- FXS simulator

Hi,

I am trying to configure a router as a FXS simulator by registering 2 IP
phones to it and having another router (branch) that will see these IP phones
as analog phones.

fxs simulator has fxo ports and branch has fxs ports

I can call from the 2 IP phones(its ringing) but when picking up the phones,
the call gets cut off straight away

Any idea?

FXS simulator:
