Abstract
A protocol gateway for setting up multimedia sessions between a first terminal, using a first protocol (for example H.323), and a second terminal, using a second protocol, said first protocol requiring the determination of a master, which protocol gateway is characterized in that it has available to it means for forcing said first terminal to assume the role of master.
Claims8
A protocol gateway for setting up multimedia sessions between a first terminal, using a first protocol, and a second terminal, using a second protocol, said first protocol requiring determination of a master, which protocol gateway is characterized in that it has available to it means for forcing said first terminal to assume the role of master.
The protocol gateway as claimed in any of the preceding claims, in which said second protocol is the SIP protocol.
A call center, characterized in that it includes a protocol gateway in accordance with any of the preceding claims.
A process for setting up a multimedia session between a first terminal using a first protocol and a second terminal using a second protocol, said first protocol requiring the determination of a master, said first and second terminals communicating by means of a protocol gateway, which process is characterized in that it includes steps of:
- sending of a message m1 to determine the master/slave status,
- sending of a response message m2 by said protocol gateway, containing a field forcing said first terminal to assume the role of master.
The process as claimed in the preceding claim, in which said first protocol is the ITU-T H.323 protocol.
The process as claimed in the preceding claim, in which said response message is a “MasterSlaveDeterminationAck” message containing a “Decision” field set to “Master”.
Dependencies are inferred from the claim text.
