Latest Patents
One of Laitman's latest patents is a method of sharing and transferring information between ISDN telephones. This method allows for the automatic sharing of calling line identifier delivery from a Work at Work (WAW) ISDN telephone to a Work at Home (WAH) ISDN telephone. It facilitates the subsequent transferring of calls to the WAH telephone if desired. Additionally, the message waiting status is shared, which helps coordinate message waiting lamps at both telephones.

The telephones automatically establish ISDN calls between themselves and exchange information regarding the status of the companion telephones.
Another significant patent involves a method and network for providing access to an information network. This intelligent network consists of several central office switches capable of receiving calls to a centrex telephone number and transmitting queries. A service control point is connected to the central office switches via an SS7 signal link. The service control point receives the query and sends a response back to the central office switch. A hub switch is also connected to the central office switches and receives the call. This hub switch contains a digital trunk service that combines the call with multiple other calls to create a data stream, which is then transmitted to an information network node.
