<p class="MsoNormal"><span lang="EN-US">Hello.</span></p>
<p class="MsoNormal"><span lang="EN-US">I’m having some problems
using websocket to communicate a webRTC client with the SIP
world.</span></p>
<p class="MsoNormal"><span lang="EN-US">I have a Kamailio with a
websocket port running on 5062, from that socket I’m
receiving a SIP INVITE from a sipML5 client with 2531 bytes
of length. When I made the capture on the other leg (the
pure SIP side) I only see a SIP INVITE with 1500 bytes.
Seems that something is fragmenting the packet but not
putting all the parts together. Could this be a problem
with Kamailio?. Does someone has the same problem?</span></p>
<p class="MsoNormal"><span lang="EN-US">Hope that someone could
help me.</span></p>
