Just wondering if the API from the link

https://developer.cisco.com/site/cer/documents/api-reference/#cisco-emergency-responder-cer-api-documentation

is all there is for CER APIs.  I've been looking for something that can be used to monitor the "last phone tracking" time on a switch in CER.

If the REST API is not the answer, then is there anything else that I can use ? 

Thx.

Discovery Status API will tell whether discovery is completed or not but it won't mention the time. There is no API for getting discovery completion time.

Thanks,

Sandeep
