Abstract
A voice over internet protocol telephone system is described in which services for handling calls invoking account codes are distributed to voicemail servers in the system. If the voicemail server associated with a particular user does not have services for handling account code calls, then the request is forwarded to another voicemail server in accordance with a predefined procedure.
