We have a configuration where we have two SIP trunks in a route group, and these trunks connect to an IVR
When the first IVR is down, automatically the second trunk is used (CM send invites no reply)
When all channels on the first IVR are used we receive a busy signal and the second IVR is not used.
Is this correct? Can we change something so that when we receive a busy on the first SIP trunk, the second is used?
