I have a Openvox 8 port FXO card and a Ethernet card in a VLAN for 16 SIP trunks. In the outbound route I have r0 (round rob.) which has 8 channels to the Openvox card. Next are the SIP trunk. So before it uses the SIP it has to have 8 calls (call #9 should go to the first SIP channel). I can only make 8 calls and the 9 call will go to fast busy. Any idea in how to fix this. The idea of the r0 is that if one of the analog ports is bad the next call will jump to the next port.
