Multimedia Service Platform uses ENUM technology to route calls addressed by E.164 telephone numbers. When routing calls based on ENUM, the SIP Proxy behaves like an ENUM client.

 

The SIP Proxy performs ENUM queries for all destinations considered PSTN numbers. The default top level domains used for queries are e164.arpa and the local domain where the ENUM numbers belonging to the platform are provisioned. You may configure a third ENUM top level domain by editing the proxy configuration settings.m4 section:

define(`ENUM_PRIVATE_TREE2', `example.com')

In this example example.com domain must have name servers configured to host NAPTR records and a valid delegation must exists for the name servers.
