Upgrade considerations for telephony

The prepareDeployment.sh script does not update the values.yaml file for telephony-related settings and does not update the settings from the existing secrets. For more information, refer to Preparing the deployment.

Configure the values.yaml file.

Compare the old values.yaml file and the new version of values.yaml file and port the settings over manually.
- Locate these settings and change the value from false to true.
```
enableJigasi: true 
enableJigasiRestartOnTrunkFailure: true 
dialInEnabled: true 
dialInDisplayEnabled: true 
enableInviteOthers: false (set to true if dial-out is enabled) 
```
- Locate these settings and configure to match the current environment. By default, these settings are blank.
```
defaultCountryCode: "" 
numbers_json: {}
```
- If necessary, add these settings to match the current environment.
```
jigasiSipServer: tmghost.example.com 
jigasiSipPort: 5060 
jigasiSipTransport: TCP 
jigasiProxyBypass: true 
```
Configure the secrets for telephony. The secrets used by telephony are not carried over from the previous version of Sametime to the new version. This must be done manually.

Secret name: auth-config-secret

Template file name: helm/templates/auth-config-secrets.yaml

Copy the application-registry.json setting from the previous file to the new file.

Secret name: sametime-global-secrets (Sametime 12) or meeting-secrets (Sametime 11.6)
Template file name: helm/templates/sametime-global-secrets.yaml

Copy the JigasiSipUri and JigasiSipPassword values from the previous file to the new file.

Secret name: catalog-config-secret
Template file name: helm/templates/catalog-config-secrets.yaml
```
**Note:** If the TMG server is configured for a self-signed certificate for HTTPS, you might have the optional extra-certs configured. In this case, copy the extra-certs value from the old helm/templates/catalog-config-secrets.yaml file and paste into the new Sametime 12 helm/catalog-config-secrets.yaml file.
```
Apply the changes to the environment. See Applying configuration changes in Kubernetes or Openshift for the steps.
