Cisco Calling Plan (Cisco PSTN) Local Survivability

[Sean Deutsch]

Hi all, wondering if someone could answer a quick question about call survivability or point me to proper documentation for Cisco Calling Plan configuration in ControlHub (not CUBE/LGW) for local survivability if connection to Webex is down. Everything I can find is related to premise based PSTN connection but I can't find anything about how failover works when the Location is configured with calling plans as the PSTN connection. With LGW you can configure route groups with different trunks. How is this accomplished for calling plans? Thank you in advance!

Hi @Sean Deutsch,

I understand that you are looking for local survivability for locations that are configured with Cisco Calling Plan.

Whether you have Local Gateway or Cisco Calling Plan for PSTN connectivity, the survivability works the same way. You must enroll Cisco IOS XE router to Webex Calling under Services >> Calling > Managed Gateways. Here in this section you have option to select the managed gateway and specify which location needs the survivability functionality. You won't see this survivability/managed gateway under Locations but you will see which gateway is acting as survivability under Services >> Calling > Managed Gateways (as shown below).

Here are the detailed guides for Webex Calling Survivability and Cisco IOS XE enrollment process:

Hello Sean,

I think this is what you are trying to do. You still can configure a Local Gateway but you can also have that local gateway be  a Site Surviavlbiilty Router.
