<p><P>PROBLEM TO BE SOLVED: To call a subscriber who has registered a new PBX instead of a disabled PBX. <P>SOLUTION: A plurality of exchange servers are grouped to configure a local distribution set. Not an SIP domain name of the exchange server but an SIP domain name of the local distribution set is attached to an SIP address of a telephone terminal registered to the exchange server which configures the local distribution set, to notify the other subscriber thereof. When each exchange server receives a message transmitted to the SIP address having the SIP domain name of the local distribution set to which the exchange server belongs as a configuration member, the exchange server replaces the SIP domain name of the destination SIP address with the SIP domain name of each exchange server configuring the local distribution set, and transmits the message. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
