A computerized apparatus having a processor, the processor being configured to perform in a telephony system that comprises:

• at least one first Private Branch Exchange (PBX) comprising a first data repository, the at least one first PBX having connected thereto at least one first communication device, the first data repository comprising information regarding the at least one first communication device and regarding a representation of at least one first user using the at least one first communication device;
• at least one second PBX comprising a second data repository;
• and
• a management system in communication with the at least one first PBX and the at least one second PBX, the management system comprising a management system data repository, wherein the management system data repository retains site settings of a logical site, the site settings are setting to be applied to entities that are included in the logical site, the entities that are included in the logical site are defined or connected to the at least one first PBX or to the at least one second PBX, wherein the logical site logically includes the at least one first communication device, the at least one first user, at least one second communication device, and at least one second user using the at least one second communication device,
• a method comprising:
• connecting the at least one second communication device to the at least one second PBX;
• and
• in response to determining that the at least one second communication device is included in the logical site, providing the site settings from the management system to the at least one second PBX;
• applying, in the at least one second PBX, the site settings to the at least one second communication device;
• thereby operating entities that are included in the logical site while being connected to the at least one first PBX and to the at least one second PBX at a same time.

A computer program product comprising a computer readable storage medium retaining program instructions, which program instructions when read by a processor, cause the processor to perform in a telephony system that comprises

• at least one first Private Branch Exchange (PBX) comprising a first data repository, the at least one first PBX having connected thereto at least one first communication device, the first data repository comprising information regarding the at least one first communication device and regarding a representation of at least one first user using the at least one first communication device;
• at least one second PBX comprising a second data repository;
• and
• a management system in communication with the at least one first PBX and the at least one second PBX, the management system comprising a management system data repository, wherein the management system data repository retains site settings of a logical site, the site settings are setting to be applied to entities that are included in the logical site, the entities that are included in the logical site are defined or connected to the at least one first PBX or to the at least one second PBX, wherein the logical site logically includes the at least one first communication device, the at least one first user, at least one second communication device, and at least one second user using the at least one second communication device,
• a method comprising:
• connecting the at least one second communication device to the at least one second PBX;
• and
• in response to determining that the at least one second communication device is included in the logical site, providing the site settings from the management system to the at least one second PBX;
• applying, in the at least one second PBX, the site settings to the at least one second communication device;
• thereby operating entities that are included in the logical site while being connected to the at least one first PBX and to the at least one second PBX at a same time.
