Abstract:
A device may receive a first session initiation protocol (SIP) message from another device, and may determine a first timestamp associated with the first SIP message. The first timestamp may represent a receipt time of the first SIP message by the device. The device may determine a second timestamp associated with a second SIP message. The second timestamp may represent a transmission time of the second SIP message by the device, and may be a response to the first SIP message. The device may determine a device latency value representing a difference between the second timestamp and the first timestamp. The device may provide the second SIP message to the other device at the transmission time. The second SIP message may include the device latency value.
