Cisco CUCM CT Integration


i want to integrate CISCO Unified Communication Manager (CUCM) with zammad. CISCO has a tool jabber sdk for webintegration.!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
