hi I had changed the sip transport for the re-invite message in the pjsua , the message will now be sending over the new transport , but when i recieve an 100 trying or 200 / Ok , the pjsua doesn't read these message ( I sure that the i recive these message due to wireshark ) and it retransmited the invite message . i think that can be a problem of endpoint or sip_manager ? can You help me to resolve this ?
