Cisco CUCM CT Integration

Hi,

i want to integrate CISCO Unified Communication Manager (CUCM) with zammad. CISCO has a tool jabber sdk for webintegration.
https://developer.cisco.com/docs/jabber-web/#!integrated-jabber/integrated-jabber
But this is much to far as our needs are. We need only the normal CTI features which are provided by Generic CTI.
Do you see a way to integrate CUCM with zammad?
It is possible to do this without jabber sdk, because these need a extra browser addon, which connects to CUCM?

Best Regards
Ulf
