I have meet the same problems, and I also have RTCP recv() error messages too. On Linux platform, I just configure PJSIP use "--enable-epoll" options, and then the problem almost gone. I only got one RTCP recv() error messages after I recompile it. Hope it can help you. -----邮件原件----- 发件人: pjsip [mailto:pjsip-bounces@lists.pjsip.org] 代表 pjsip-request@lists.pjsip.org 发送时间: 2013年8月26日 16:58 收件人: pjsip@lists.pjsip.org 主题: pjsip Digest, Vol 72, Issue 75 Send pjsip mailing list submissions to pjsip@lists.pjsip.org To subscribe or unsubscribe via the World Wide Web, visit http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org or, via email, send a message with subject or body 'help' to pjsip-request@lists.pjsip.org You can reach the person managing the list at pjsip-owner@lists.pjsip.org When replying, please edit your Subject line so it is more specific than "Re: Contents of pjsip digest..."

Hi For some reason i need implement own protocol to change all sip/rtp packets. Can you suggest me a right way? Alex

Hi Alex, Then why dont you write your own stack like pjsip from scratch as completely changig SIP and RTP changes all the pjsip.

Hi, for the SIP signaling I think you should be able to accomplish this with implementing a pjsip module in which you modify the messages when they are received and sent. Have a look at pjsip_endpt_register_module(). For the RTP traffic you can implement your own media transport that uses one of the existing media transports as a slave transport and then do your own modifications on the RX/TX packets. Have a look at http://www.pjsip.org/docs/latest/pjmedia/docs/html/group__PJMEDIA__TRANSPORT.htm Good luck!

status = pjsip_endpt_register_module(pjsua_get_pjsip_endpt(),
                                     &mod_default_handler);
if (status != PJ_SUCCESS)
    return status;

Hi for module, looks like good proposition, but: status = pjsip_endpt_register_module(pjsua_get_pjsip_endpt(), &mod_default_handler); if (status != PJ_SUCCESS) return status; /* The module instance. */ static pjsip_module mod_default_handler = { NULL, NULL, /* prev, next. */ { "mod-default-handler", 19 }, /* Name. */ -1, /* Id */ PJSIP_MOD_PRIORITY_APPLICATION+99, /* Priority */ NULL, /* load() */ NULL, /* start() */ NULL, /* stop() */ NULL, /* unload() */ &default_mod_on_rx_request, /* on_rx_request() */ NULL, /* on_rx_response() */ NULL, /* on_tx_request. */ NULL, /* on_tx_response() */ NULL, /* on_tsx_state() */ }; static pj_bool_t default_mod_on_rx_request(pjsip_rx_data *rdata) { PJ_LOG(1,(THIS_FILE, "default_mod_on_rx_request")); } show nothing on console. I call pjsip_endpt_register_module after pjsua_init of course. May u suggest a code snippet?

Dan i'm little confusing for you proposition to using module. Before sending signalling packet on_tx_request gives me pjsip_tx_data *tdata structure. Inside there i find only one member, which i think i can using pjsip_msg *msg; but there is i can change body only, but not headers. Simply enumeration: const pjsip_hdr *h; unsigned cnt = 0; h = tdata->msg->hdr.next; while (h != &tdata->msg->hdr) { ++cnt; h = h->next; PJ_LOG(1,(THIS_FILE, "proxy_on_tx_request hsrc.name->%s hsrc.sname->%s", h->name.ptr,h->sname.ptr)); } Show me only header attrubutes, but not values inside. I didn't find possibility to change final sip message there, all buffers (pjsip_buffer) empty there. Thank you for u future helps, Alex.
