The present description relates to an adaptation proxy, a computer system, a computer-implemented method, and a computer program product for enabling presence and remote call control services between client devices served by different SIP servers. In one aspect, the adaptation proxy integrable into a computer system for enabling presence and remote call control services between client devices served by different SIP servers may comprise: an SIP adaptor operable to transform and to transport SIP messages between the client devices served by the different SIP servers; a CSTA gateway operable to convert a CSTA event supported by a second SIP server of the SIP servers into a format supported by a first SIP server of the SIP servers, wherein the CSTA event independently operates over the SIP messages to communicate remote control commands; and a presence integrator operable to notify a change to a call state of a first client device from the client devices served by the first SIP server to the second SIP server after having performed a mapping between the changed call state and a corresponding presence state of a second client device from the client devices served by the second SIP server so as to integrate presence information of the first client device and the second client device.
