[OpenSER-Devel] another tcp problem

[Juha Heinanen]

i did some more openser trunk tcp tests.  tcp works ok if openser routes
a request from outside to a tcp registered ua.

the problem appears when request to a tcp connected ua or to a tcp
connected other openser is issued via t_uac_dlg.

in that case, debug does not show any error messages and the last debug
line is:

Oct 28 09:53:28 foobar /usr/sbin/openser[10776]: core:tcp_send: c=0xb38c57a8, n=8 

but nothing happens, i.e., wireshark does not show any packets coming
out from the proxy and it looks like the process handling t_uac_dlg
never terminates.  by the way, is there a way to figure out is an
openser process is currently handling a request or if it is idle?

i did this test using a click-to-dial application by trying to
click-to-dial to a tcp registered nokia phone.  if i register using udp,
t_uac_dlg works without problems.

full debug is below.
