Scenario 3: Multiple HMCP Media Servers
For 500+ PBX users or 200+ call center agent installations that require more than 200
recording sessions, you may deploy multiple HMCP Media servers to achieve load bal-
ancing and failover protection. The following example shows two HMCP media servers to
provide up to 2,000 G.711 VPR, 400 compressed codec, and 240 members of Station or
MeetMe conferencing.
To achieve load balancing, you need to divide and assign IP extensions to different Home
Media Server IDs. The following guidelines may help you make decisions when assigning
IP extensions to different Home Media Server IDs.
• Equally divide the IP extensions that require centralized recording and assign them
to different HMCP Media servers.
• Equally divide the remote works who connects to system using G.723/G.729 and
assign them to different HMCP Media servers.
• For the remaining IP extensions, assign extensions in a department in the same
Media server.
