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