I have configured 31 channels in single group its working well, but I have to split channels for Inbound & outbound. For example I need to use 1-15 channels for only Inbound and 17-31 channels for outbound trunk. How can I define this in freetdm.conf file, is it possible to split this channels or is there any other way to do for the same.
