Hi!

My name is Attila Gál, I'm new to the list.
I found the list in order to solve a strange problem, but I think I  
tried everything I could.

The case is, that I develop a simple J2ME application. In WTK 2.5,  
there is the JSR180 SIP stack implementation, so first I read  
carefully the docs.
I have to address an Asterisk server, so I have set up a  
SIPClientConnection, and a SipConnectionNotifier object before that.  
The SipConnectionNotifier needs a port number, which it will listen  
to.( I used 5060)
After that, I sent a REGISTER command with my SIPClientConnection  
object, to the address (port 5060).
The server gets the request from my machine where the emulator runs,  
and sends back the response, which I never get.
I observed the UDP traffic, and I saw that my request was sent from a  
random port (eg. 1289), instead of 5060, the server answers to this  
port, instead of 5060, which I listen to.

After I recognized this, I thought that my Contact field's value was  
bad, but I tried many things, the answer always went to the port,  
where the request came from, and not to 5060.

After that I started to examine, if I could find out the effective  
port, where my request was sent from, but I couldn't find anything,  
from the SIP classes.


I googled many days, and found 3-4 post on forums, about the same problem.

but no solution or any workaround.


Does anyone have any ideas?


Thanks in advance,
