As mentioned earlier, customers use unique IPs for each sip-interface and the same realm-id on the network-interface that us configured for your tunnel. This configuration is the same for each sip-interface. This means a single tunnel is sufficient when you are using unique IPs.

To achieve OLIP, however, you use different realm-ids across sip-interfaces, and configure tunnels on each corresponding network-interface. This means that OLIP on the access side requires multiple tunnels, as shown below.
