Hello,
I'm trying to register the pjsua sip client to use the transport = tcp
I'm using the following command for register :
pjsua-i386-Win32-vc8-Debug.exe --id="sip:409 at 192.168.3.7;transport=tcp"
--registrar="sip:192.168.3.7;transport=tcp"
--proxy="sip:192.168.3.7;transport=tcp"
The phone registers and everything is fine. I make a call to
sip:402 at 192.168.3.7
I get the following wireshark capture:

If you notice, all the communication is on TCP till the
<Request: ACK sip:402 at 192.168.3.7:5060>.
This subsequently causes a
ICMP 190 Destination unreachable (Port unreachable)
What is the solution for this. Why is it that the ACK is going on the UDP.
Please guide me, and let me know if this query is adressed previously. if
so, please point me to the thread.
Additional data :
I'm running the phone on the Windows 7 machine.

B. S. Vinayaka
