Gateway service API (wsapi) xcdr keeplive

Chester Rieman — Fri, 19 Aug 2022 20:41:21 GMT

Hi Folks,

Trying to use WSAPI to gather CDRs from a CUBE. I can get the app registered and it receives CDRs but fails after a time due to an inaccurate ResponseXcdrProbing message my app sends back. I followed the example of the xcc probing response shown in the doc https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/CUCIS_API/CUCIS_API_Guide/CUCISA_MSG.html but I get back a 200 with Unknown XML tag.

Here is the probe response I am sending.

<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n
<soapenv:Envelope xmlns:soapenv=\"http://www.w3.org/2003/05/soap-envelope\">\n
<soapenv:Body>\n<ResponseXcdrProbing xmlns=\"http://www.cisco.com/schema/cisco_xcdr/v1_0\">\n
<msgHeader>\n
{RID}\n
{TID}\n
</msgHeader>\n
<sequence>{SEQ}</sequence>\n
</ResponseXcdrProbing>\n
</soapenv:Body>\n
</soapenv:Envelope>"

Here is the error I get back in the 200 OK

I could not find a good example of ResponseXcdrProbing but there was an example of ResponseXccProbing in the doc which is what I went by, apparently there is a difference between XccProbing and XcdrProbing responses. If anyone has a working example of ResponseXcdrProbing, I would love to see what it looks like.

Thanks!

Can you try <ResponseXcdrProbings> with an 's' on the end (for extra confusion?)

Attaching a copy of the WSDLs I found - not sure if the matching version is available on the box itself..?

Thanks David, I wondered about the wsdl - I did find a copy in another community, would be nice if we could get it via the normal method.

Anyway - No joy

I see this in the debugs and wondering what namespace it wants:

I'm open to any other suggestions you may have, I'm down to just trying random changes in my response message.

Thanks!

This post has the same errors except for the xcc provider, I reached to see if/how he resolved it.

Maybe try removing the namespace altogether from <ResponseXcdrProbings>?
The WSDL above is fairly broken, it seems. After hacking on it some to the point I could generate a request in SoapUI, I noted that no namespace seems to be included in the requests, e.g.:

As there is not much documentation available, and few (no?) folks still around familiar with it, might need to inquire with TAC 😕
