The H.223 and H.245 protocols are used to establish multimedia calls between endpoints over circuit switched networks. These protocols come into play after successful call completion between the multimedia endpoints. The initial SS7/ISDN call setup messages contain an octet that indicate that the call will utilize H.223/H.245. Feature F-5230 ‘Multimedia Call Routing' supports routing calls based on the presence of this specific octet. Thus with this feature, routing is configured using the new routing criteria type 'Multimedia Call'.
