In the lines of the form "Set(PUSH(rrItem)=SIP-1601534775)", the ids of providers are listed, among which outgoing ones should be evenly distributed. The ID can be copied in the browser's address bar when editing the provider. The "busyLevel" variable defines the maximum allowed number of simultaneous calls through the provider.

For each provider, you will need to describe the outgoing route. The template in the routes must be the same.
