Complete these tasks to update a dialing-context configuration element.

1. Retrieve the dialing-context configuration you want to modify.

   curl -X GET -o response.xml \
       --header "Accept: application/xml" \
       --header "Authorization: Bearer $TOKEN" \
       "https://10.0.0.2/rest/v1.2/configuration/configElements?elementType=dialing-context&name=<childKey>&parent=<parentKey>&dial-pattern=<removePrefix/pattern>"

   If the dialing context you want to retrieve is at the root level, leave the parent parameter blank. The dial-pattern parameter is optional.

   The response is saved to the file response.xml.
2. Copy the content between the opening and closing <configElement> tags to a new file called dialing-context.xml.

   If you are on a Linux system with xmllint installed, you may optionally format the XML before writing it to the file system.

   sed -n '/<configElement>/,/<\/configElement>/p' response.xml | xmllint --format - > dialing-context.xml

3. Update the values in the XML file to their desired values.
4. Acquire the configuration lock.

   curl -X POST \
       --header "Accept: application/xml" \
       --header "Authorization: Bearer $TOKEN" \
       "https://10.0.0.2/rest/v1.2/configuration/lock"

5. Update the dialing-context configuration element.

   curl -X PUT \
       -d@dialing-context.xml \
       --header "Accept: application/xml" \
       --header "Authorization: Bearer $TOKEN" \
       "https://10.0.0.2/rest/v1.2/configuration/configElements"

6. If done editing the configuration, save, verify, and activate the configuration.
7. Release the configuration lock.

   curl -X POST \
       --header "Accept: application/xml" \
       --header "Authorization: Bearer $TOKEN" \
       "https://10.0.0.2/rest/v1.2/configuration/unlock"
