seq-number

Syntax	seq-number
	undo seq-number
View	VoFR entity view
Parameter	None
Description	Use the seq-numbercommand to configure the VoFR packets sent by the local
	voice gateway to carry a sequence number.
	Use the undo seq-numbercommand to restore the default.
	By default, the VoFR packets sent by the local voice gateway do not carry any
	sequence number.
n	■ Usually, the configuration of the originating voice gateway determines whether
	VoFR packets carry a sequence number.
	■ Routers of some manufacturers do not comply with the above rule, but force
	VoFR packets to carry a sequence number when a specific codec is adopted. If
	a call failure or severe voice distortion occurs when the device is interconnected
	with a router of a third party, you can try making VoFR packets carry a
	sequence number.
	■ The terminating voice gateway can determine whether any voice packet loss,
	duplicate voice packet, or out-of-sequence occurs according to sequence
	numbers, which helps compensate voice. However, the use of sequence
	numbers will increase the required network bandwidth. Therefore, you can
	determine whether to use sequence numbers according to the actual
	condition.
