i have a question about inbound routes that i cant achieve it
on outbound route we can set multiple trunks for congestion
but in inbound route we can only choose 1 Trunk for destination
we have multiple trunk with our provider
how can we have inbound route for incoming calls from another PBX system to use all of this trunks on our issabel system when first trunk is busy?
short is : we want incoming calls from another PBX system to our issabel goes thorugh all trunks
trunk1 : when busy go trunk 2 : when busy go trunk3 and ...
