Abstract:
A method of managing multi-media call flows, comprising:establishing a call in an environment having a first signaling protocol to an environment having a second signaling protocol; identifying in the first signaling protocol that the call is going to the environment having the second signaling protocol; replacing a first signaling element of the first signaling protocol with a corresponding second signaling element of the second protocol; identifying in the second signaling protocol that the call is going to a second environment having the first signaling protocol; replacing the second signaling element of the second signaling protocol with the corresponding first signaling element of the first protocol; and completing the call on the basis of the second signaling protocol with the corresponding first signaling element of the first protocol; wherein a first user sending to a second user sends on an address and a port number address of the second user, and the second user sending to the first user sends on an address and port number of the first user.
