Usage guidelines
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.
