Hi,
I just downloaded the latest version of pjsip (0.8) and built it in
Windows XP. The build worked fine. I set up an user account on brekeke
server that allows TCP connection from client and fired up
pjsua_vc8d.exe and it complained with the following result
>>>
Account list:
[ 0] <sip:192.168.1.2:5060;transport=TCP>: does not register
Online status: Online
*[ 1] sip:2001 at 192.168.1.3: 503/Service Unavailable (expires=-1)
Online status: Online
Buddy list:
I did a packet capture and I found that no packets were sent and I
found this message on the console
10:20:19.023 tsx00CF83DC Failed to send Request msg REGISTER/cseq=18509 (tdt
a00CF7348)! err=171060 (Unsupported transport (PJSIP_EUNSUPTRANSPORT))
10:20:19.023 pjsua_acc.c SIP registration failed, status=503 (Service Unavai
lable)
I see that TCP transport is not supported. I would like to know how do
I enable support for TCP.
Also, I have another related question. The TCP listen port is 5060. So
PJSIP listens for incoming SIP requests on that port. When I send out
SIP requests, do I use the same TCP connection with the server or do I
use another TCP connection with an ephemeral port on the local machine
and talk to TCP port 5060 on the remote host. The reason I am asking
this question, is I would like to keep the TCP connection between the
client and the server open for as long as the the client is online
(i.e. connected to the network). Therefore, I can receive incoming
requests on the same TCP connection. I would like to know if it is
feasible to do so.
Thanks again
Regards
Knight
