Abstract: In an embodiment, an originating device sends a request, to a server, to initiate a full-duplex session with a target device. Responsive to the full-duplex request, a half-duplex session is set-up from the originating device to the target device before the full-duplex session is set-up. The tar-get device indicates its acceptance of the half-duplex session, receives half--duplex media from the originating device and selectively indicates its ac-ceptance of the full-duplex session. In another embodiment, during a ses-sion currently supported either by half-duplex or full-duplex, the server ar-bitrating the session receives a request from one of the session participants to transition the session to another duplex-type. The server then selectively transitions the duplex-type of the session.

Patent CA-2747127-A1 (CA)
Inventor: ILG THOMAS SIMON
IPC: C07H19/207
Filed: 2009-12-07
Abstract: A process is disclosed for the production of cyclic di-guanosine monophosphate (c-di-GMP) without the use of protecting groups by means of an enzymatic synthesis. The process comprises the coupling of two guanosine triphosphate (GTP) molecules so as to form a c-di-GMP molecule. This is done under the influence of a mutant diguanylate cyclase (DGC) compris-ing the amino acid sequence V153M154G155G156. It has been found that the DGC is obtainable from inclusion bodies, and therewith can be made available in amounts sufficient to improve the c-di-GMP  synthesis. Particularly, the latter synthesis can be conducted in a one-pot method starting from commercially available bulk chemicals and allows upscaling to a commercial produc-tion scale.
