How do I discover Cisco IP Phones via HTTP classification?

[Erick18]

I am running into an issue trying to discovery Cisco IP phones via HTTP classification. I am able to get an xml response by going to http://ipadress/DeviceInformationX but whenever I try to create a new pattern and use the debug feature I am running into the following errors. "Host detection failed for IP address  When looking at the discovery logs this is the error: 2020-11-09 08:02:00: Identification Engine: Discovery status is FAILURE, Identification sections in pattern failed: section: discovery, error: Match step predicate is not matched. 

Thanks, 

Erick

Hi SiD, 

I am actually creating the pattern from scratch and don't have any steps added to the pattern yet. I have created the http classification which triggers the custom pattern I have created. However in the pattern designer I click debug and get the error: Host detection failed for IP address. 

Thanks,

Erick

I was actually able to resolve the debug error I was receiving by using the steps outlined in creating a pattern for serverless discovery. By adding the url as an input parameter I was able to debug without the need for a host. I then was able to create my pattern. After creating my pattern I removed the input parameter and ran the discovery for configuration items. 

Here are the steps to create a pattern for serverless discovery: https://docs.servicenow.com/bundle/paris-it-operations-management/page/product/discovery/task/create-pattern-for-serverless.html#create-pattern-for-serverless

Could you go more into details on how you achieved this? I've been attempting to research here and there on how to do whilst also, researching on how to to even pull these in via SNMP (or extension from Cisco Call Manager, which also isn't being discovered). Any info is helpful, if you have the chance. Thanks in advance.
