Hi Wim Taymens, 

This is the pipeline i used for testing:

gst-launch-0.10 -v filesrc location="/bulk/MainAgarKahoon.mp3" ! audio/mpeg,
mpegversion=1, layer=3 ! decodebin ! audioconvert ! audio/x-raw-int,
channels=2, depth=16, width=16, rate=48000, endianness=4321 ! rtpL16pay
min-ptime=2660000 max-ptime=2660000 pt=97 ssrc=0 timestamp-offset=0
seqnum-offset=0 ! udpsink host=239.1.2.12 port=51000 sync=true qos=true

As you said, i set the min-ptime and max-ptime to 2660000. 

Here is the tcpdump of the same:
