You have a Skype for Business infrastructure that contains four servers. The servers are configured as shown in the following table.
The infrastructure contains a hardware load balancer named HLB1. The company has an IP-PBX system. The IP-PBX supports media bypass. The IP-PBX has a Session Initiation Protocol (SIP) trunk configured. Each user has a desktop phone that connects to the IP-PBX. Each computer has a Skype for Business-qualified headset.
The company plans to implement Enterprise Voice and to use existing SIP trunks.
