The
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.
The below table provides just a few examples of IP address/alternate IP address/alternate Media IP address combinations equaling 4,096 IP addresses.
Most user configurations will not need 4,096 IP interfaces.
Alternate Media IPs are chosen based on Round Robin method (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, 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.
The following constraints apply:
The CLI command syntax to configure alternate media IP addresses is shown below. For details, see IP Interface Group - CLI page.
% set addressContext <addressContext name> ipInterfaceGroup <interface group> ipInterface <interface> altMediaIpAddresses <IPv4/IPv6 address>
