All, Recently, we try use pjsip stack to build our Application server, we find the stack can NOT cache the message, instead, it's just put each message to the application layer, including the retransmitted message. Whether the pjsip stack has some mechanisms to cache the retransmitted message? Your response is very appreciated!
