Hi all, I want to deploy the next scenario. Multiple users assigned to a group somehow inside elastix and then that group should be able to use just one sip trunk to a voip provider over internet. The idea behind this is because the elastix should manage several sip trunks to different service providers with different price plans. The customers in a group should be able to use just one sip trunk which is connected to one voip provider. Is this possible with elastix? Do I need to execute several VMs or running just one instance is enough?
