Asterisk and Cisco Phone (interoperability) - how to set up?

Question

Asterisk

Good afternoon
We in the company decided to switch from CUCM to Asterisk. The phones became friends, everything seems to be fine, but an unpleasant moment was discovered - the missed / dialed / incoming lists do not work.
Google did not give a solution, but said that in the standard bundle this information is given through the http server and xml.
So the question is, has anyone done this? Where can I read about the formation of this xml? Or are there other ways?
Thanks in advance
PS The options "stay on CUCM" or "change all phones in the organization" are not possible.

The problem was solved though. It was all in the parameter in the config. We had false. When set to true, everything appeared and worked. And out of the box. And the most annoying thing is that 3 integrators and 2 offices that specialize in Asterisk could not answer this for me.
And we found it purely by chance, compared our configs with the configs sent by other guys...

@Dr-Wut you need a web server with CGI support and a link to the services of this server in the phone configs.
