if you are in a hurry, then maybe you can find a consultant. The public
mailing list is best effort, many of us having other
jobs/travelings/vacations, and cannot guarantee a solution in a given
time. Besides, your deployment is particular, running solaris, which may
require to get access to fix it.
I looked over the log udp_rtpproxy_log and rtpproxy is found at start up
(pids: 24610, ...). Then one of the processes (24613, line 1462) can
communicate fine with it for an INVITE. The second process gets the
error (24613, line 1630). I assume it may have to do something with the
limits of your system. Are there any limits on writev() or UDP on
solaris? Not being is solaris devel, maybe you can find someone else to
answer if you don't know.
Cheers,
Daniel
