Hi, I am using pjsip 2.7.1 version, I can not send messages through sip server. when i send message through sip server, it shows just '()' at the receiver end. I did following procedure 1. run the pjsua-x86_64-unknown-linux-gnu 2. registered into iptel.org using sip:xxx@iptel.org 3. pressed i to send message 4. enter the reciver sip address sip:yyy@iptel.org 5. the type the message and pressed enter. after this, the reciver does not display the message and wireshark logs shows the message contect length is zero (0). How can i fix this issue? Is there any format to send message through sip server? I tried to send message throgh IP in local network, The receiver shows messge content in this case. I also checked with pjsip 2.8 version, it shows the same thing Thanks in advance Regards, Allwyn
