SIP Trunking SPLs for Specific Service Providers

The ESBC includes SPLs to support trunking requirements for specific service providers. This support includes identifying requests within applicable sessions and manipulating values before forwarding subsequent requests.

Using these SPLs, you can configure your ESBC to comply with requirements, manipulate signaling, and time traffic to inter-operate with SIP trunks:

• The surrogate registration SPL feature applies to both NTT and KDDI environments. The associated random contact exclusion child feature, however applies only to KDDI environments.
• The NTT Message coverter SPL feature applies only the NTT environments.

Depending on version, these packages are built into the ESBC base code, in which case you don't have to upload them.
