Hi Gang Liu,
i found a code snippet in pjusa for info request, but this code will
send a DTMF string(dtmf-relay). Question, do you know the right "sip-style" to send
the info request without DTMF, for the KeepAlive i think i need a empty request.
It is possible to use another msg_data.content_type?
What do you think?
thank you
mark
const pj_str_t SIP_INFO = pj_str("INFO");
03703 pj_str_t digits;
03719 digits = pj_str(buf);
03720 for (i=0; i<digits.slen; ++i) {
03721 pjsua_msg_data msg_data;
03722 char body[80];
03723
03724 pjsua_msg_data_init(&msg_data);
03725 msg_data.content_type = pj_str("application/dtmf-relay");
03726
03727 pj_ansi_snprintf(body, sizeof(body),
03728 "Signal=%c\r\n"
03729 "Duration=160",
03730 buf[i]);
03731 msg_data.msg_body = pj_str(body);
03732
03733 status = pjsua_call_send_request(current_call, &SIP_INFO,
03734 &msg_data);

Betreff: Re: [pjsip] End to End KeepAlive
If both agent are your program, you could use OPTIONS or INFO request to check signal path.
session-timer not supported by pjsip current version.

Hi,
I have this situation:
SIP-Agent 1 <---> Registrar <-----> SIP Agent 2
If i kill the connection (cut the network) between Registrar and SIP Agent 2, Agent 1 will
not close the connection.
If it possible to make a simple End - to End Keep Alive. I tryed REINVITE and UPDATE for Agent 1
but both will rebuild my media streams (not really good for the voice)
regards
Mark
