PTime Configuration
Ptime gives the length of time in milliseconds represented by the media in a packet. The
SDP in the INVITE request sent by the calling party carries the Ptime attribute, which
indicates that the packing duration of the calling party's media is the value carried by
Ptime. After receiving the request message, the server replies with the Ptime attribute in
the SDP in 200 OK, indicating that the server-side support for the packaging time of the
media is the value carried by Ptime. The caller negotiates according to the Ptime attribute
carried in the SDP in the 200 OK, and finally sends the media package time, that is, the
Ptime value. To set it up, go to Account > Advanced >Call.
Parameter Set-up:
•
PTime: you can disable the PTime feature. Or set up it from 10 to 60seconds.
