Hi, PjSIP 1.3 said it supported large message transfer switching TCP automatically. So my question is: How large can it transfer using send_request_msg() in a call? For application, Does it need do extra efforts to deal with the large message receiving. Eg: wait until the end of the message. or the PjSIP has done this for us and we just using the callback of the PjSIP. -- Thanks & Best Regards!

Not sure if I got the question right. The feature of auto-switch to TCP in 1.3 is: whenever the SIP message size (that is about to be sent via UDP) exceeds PJSIP_UDP_SIZE_THRESHOLD (default value is 1300 bytes), the stack will automatically switch transport to TCP, if it fails (e.g: timeout, TCP transport not available), the message will still be sent via UDP. While maximum message size is configurable via PJSIP_MAX_PKT_LEN (default is 2000 bytes). > > For application, Does it need do extra efforts to deal with the large > message receiving.

Hi Nanang lzzuddin, Large message? Do you mean pjsip 1.3 supports sending large message such as big files? Does it do that using MSRP protocol? 2009/7/14 Nanang Izzuddin <nanang@pjsip.org> > Hi, > > On Tue, Jul 14, 2009 at 4:31 PM, Qh guo<rashaguo@gmail.com> wrote: > > Hi, > > > > PjSIP 1.3 said it supported large message transfer switching TCP > > automatically. > > > > So my question is: How large can it transfer using send_request_msg() in > a > > call? > > Not sure if I got the question right.

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@gmail.com> wrote: > Hi Nanang lzzuddin, > > Large message?

Great! Many thanks Nanang! You got my question. "large message" I said means the large request message. One more question: PJSIP_MAX_PKT_LEN, this macro, Can I configure it with big value? like 10M bytes? Will it cause lower efficiency for PjSIP? And if it was configureed with default value and no TCP available, can pjsip send request message with larger message body (much more lager than 2000bytes) successfully?

AFAIK, no, PJSIP_MAX_PKT_LEN is there for something :) Regards, nanang

Hi, Here I will clarify what I concern. Now SIP is used in VoIP mostly but it can be used in many fields from SIP feature. Eg.: It likes HTTP protocol and even replaces HTTP which uses TCP transport. So I am working on an application based on SIP, and it can work for VoIP + Http Like application (send request response with SIP msg body) and the later will need TCP support if large message. So, I am not sure PjSIP group have cared about this part, that is sending request and response using SIP like HTTP did. I hope pjSIP can extend a module which can deal with it. It will make SIP used in much more fields not only VoIP IM. Even Web server...
