The
The
supports configuring up to
14 254 alternate media IP addresses using the parameter
altMediaIpAddresses when configuring IP interfaces. Any combination of IPv4 and IPv6 is allowed and applies to all supported protocols (SIP, H.323, GW-GW).
A total of 4,096 IP Addresses are supported for
and 8,192 IP Addresses are supported
for , which is the system limit on IP addresses for each variant.
The below table provides just a few examples of IP address/alternate IP address/alternate Media IP address combinations equaling 4,096 IP addresses.

| Note |
|---|
Most user configurations will not need 4,096 IP interfaces. |
Alternate Media IPs are chosen based on Round Robin method (e.g. for example, the first call uses the primary IP and port, the second call uses the first configured alternate Media IP and port, the third call uses the second configured alternate Media IP, etc.and so on). Each alternate Media IP must be unique across all interfaces in the same addressContext. However, the IPs may overlap between SIP, H.323 or Gateway signaling IP addresses in the same Address Context.
