- 1. ) a method of audio (as defined herein) transmission over a network where audio frames are sent in UDP packets, wherein the audio frames are overlapped by at least one for each UDP packet.
-
13. ) A method of internet telephony on a network where audio (as defined herein) frames are sent in UDP packets, wherein at least one monitoring station is provided in the network, and wherein the at least one monitoring station periodically sends at least one packet to at least one destination of interest to obtain quality of service information, the quality of service information being used to dynamically alter call set-up.
-
24. ) A method as claimed in 17, wherein the first destination is capable of measuring jitter between packets arriving from the at least one monitoring station.
-
28. ) A packet to be used to provide quality of service information about a telecommunications network, the packet having a set-up substantially the same as the set-up of a standard packet for voice over Internet protocol calls.
-
34. ) A packet as claimed in clam 33, wherein the packet is sent over the telecommunication network to emulate the standard packet.
