No, I got it wrong about "large message" then :) The auto-switch to TCP feature in pjsip 1.3 I was talking about is related to RFC 3261 section 18.1.1: --- * If a request is within 200 bytes of the path MTU, or if it is larger * than 1300 bytes and the path MTU is unknown, the request MUST be sent * using an RFC 2914 [43] congestion controlled transport protocol, such * as TCP. --- Regards, nanang On Wed, Jul 15, 2009 at 7:30 AM, xutm<xutom2006 at gmail.com> wrote: > Hi Nanang lzzuddin, > > Large message?
