Abstract
A communication session over a network is facilitated. A signaling datagram from a source device having a source identity may be intercepted by a network device, and a response datagram may be generated for instructing the source device to send a subsequent datagram to the network device. The signaling datagram may be forwarded to a SIP server, where the SIP server associates the source identity with the network device acting on behalf of the source device, and where the SIP server operates to connect a destination device with the source device to establish a communication session over the network. The subsequent datagram may be received from the source device, and the subsequent datagram may be made available to the destination device via the network.

33. A method, performed by a network device, the method comprising:
-
intercepting, by the network device, a first datagram from a source device; forwarding, by the network device and in response to intercepting the first datagram, a response datagram to the source device, the response datagram instructing the source device to send a subsequent datagram to the network device; receiving, by the network device, the subsequent datagram from the source device; and forwarding, by the network device, the subsequent datagram to a destination device to establish a communication session between the source device and the destination device. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. A network device comprising:
a processor to; intercept a first datagram from a source device; forward, in response to intercepting the first datagram, a response datagram to the source device, the response datagram instructing the source device to send a subsequent datagram to the network device; receive the subsequent datagram from the source device; and forward the subsequent datagram to a destination device to establish a communication session between the source device and the destination device. - View Dependent Claims (41, 42, 43, 44, 45, 46)

47. A system comprising:
a network device comprising; an input interface, an output interface, and a processor to; intercept, via the input interface, a registration datagram from a source device, send a redirection datagram to cause the source device to direct a subsequent datagram to the network device, send registration information extracted from the registration datagram to a registrar via the output interface, the registration datagram causing the registrar to send a subsequent datagram, intended for the source device, to the network device, where the network device acts on behalf of the source device, receive, via the input interface, the subsequent datagram, where the subsequent datagram includes one of bearer data or signaling data, monitor the signaling data when the subsequent datagram includes the signaling data, and apply quality of service monitoring to the bearer data when the subsequent datagram includes the bearer data. - View Dependent Claims (48, 49, 50, 51, 52)
