Packetization Time
Ptime (Packetization Time) is a measurement of the duration (in milliseconds) of the audio data in each RTP packet
sent to the destination, and defines how much network bandwidth is used for the RTP stream transfer. 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.
