We have a VS-GW1600 (Model Name: VS-GGU-E2M0400, Software Version: 2.1.3 , Hardware Version: Date 2012-11-09 FPGA 11 Hardware 00 ) and we integrated it whith a asterisk customized pabx via a sip trunk.
When we try a outbound call, we can't get a ring tone. We generated it with a Dial cmd parameter in asterisk, but we need receive some informations from gsm operator (mailvoice, number don't exists), using dial parameter we can't ear them.
We testing with "progress inband" option to "yes", but unsucessfully. Can you help us?
