Emergency Dial Configurations

To dial emergency numbers, you add dial patterns to the corporate context child context for the emergency numbers. Configure these dial patterns with a Replace URI transformation that inserts the RFC 5031 compliant URN for emergency services. The following contexts and routes show examples of such a configuration. The last table in this topic shows the results of this configuration.

Dial Patterns Configured for the acme.bedford context

Prefix Pattern Country Code Replace Prefix Replace URI Go To Context
911 URN:service:sos

Dial Patterns Configured for the acme.madrid context

Prefix Pattern Country Code Replace Prefix Replace URI Go To Context
112 URN:service:sos

Dial Patterns Configured for the acme.berlin context

Prefix Pattern Country Code Replace Prefix Replace URI Go To Context
112 URN:service:sos

In addition to the preceding dial patterns, the system needs three new routes.

Route # Source Agent Calling # Called # Dest Agent Route Cost
#1 * 1* "service:sos" * PSTN-NA 0
#2 * 34* "service:sos" * PSTN-MAD 0
#3 * 49* "service:sos" * PSTN-BER 0

This configuration produces the following results.
