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.
| From | Dial String | Transformations | Result |
|---|---|---|---|
| acme.bedford | 911 | URN:service:sos | Call is directed to PSTN-NA as emergency URN |
| acme.madrid | 112 | URN:service:sos | Call is directed to PSTN-MAD as emergency URN |
| acme.berlin | 112 | URN:service:sos | Call is directed to PSTN-BER as emergency URN |
