If you have a codec that has silence suppression enabled, then you may get all kind of arbitrary lengths for packets (as silence suppression may kick in at any time). Disable silence suppression on both ends and retest. If you are still seeing variable length packets then there might be a problem.

Hello,
We have a proxy server setup that runs Kamailiov3.0.1 + RTPProxyv1.2.1. Nathelper support has been enabled in Kamailio.
On a certain route, we call force_rtp_proxy("z120"), i.e. with resizing parameter 'z' and argument 120ms. During a call where endpoints have negotiated the use of G729, RTPProxy sends packets with ptime=12 (120ms), however occasionally rtpproxy sends packets with ptime 6(60ms), 8(80ms), 4(40ms).
Under what circumstance would RTPProxy send packets with ptime < 12 ?
