Packetization Time
Ptime (Packetization Time) is measurement of the duration (in milliseconds) of the audio
data in each RTP packet sent to the destination, and hence it defines how much network
bandwidth is used for transfer of the RTP stream. Before establishing a conversation,
codec and ptime are negotiated through SIP signaling. The valid values of ptime range
from 10 to 60, in increments of 10 milliseconds. The default ptime is 20ms. You can also
disable the ptime negotiation.
Procedure
Configuration changes can be performed using the configuration files or locally.
