Abstract

A first device is disclosed, which includes a processor and a memory in communication with the processor. The memory includes executable instructions that, when executed by the processor, cause the processor to control the first device to perform functions of sending a first message to a second device, the first message including first candidate addresses available for the first device to establish a media session with the second device, the first candidate addresses including a first media server network address allocated from a media relay server group comprising at least one media relay server; receiving a second message from the second device, the second message including second candidate addresses available for the second device to establish the media session with the first device, the second candidate addresses including a second media server network address allocated from the media relay server group; and establishing the media session between the first and second devices using an address pair comprising the first and second media server network addresses. The first device thus reduces a call set up time by establishing a media session using the first and second media server network addresses.
