I have an openvox gateway VS-GWM400 with 6 SIM cards, each is a different line
I have configured one trunk port to a freepbx server.
I am having problems with creating an inbound route to the freepbx server. When a call is made to one of the SIM cards, the call works very well. The problem comes in when the same number is dialled while another call is in progress. The original call is put in waiting while the second call continues from where the first call left off.
