Re: [SR-Users] How does dlg_bridge work?

I found the root cause of it. This is because I am terminating sessions on Kamailio, by sending 200 ok from config. I don’t specify callee “Contact” at that point. Even though there are active chat sessions, dialog are not shown with cmd below. I am attaching relevant config below - Questions: 1. Can dlg_refer work without callee contact details? Or 2. Should I make up some contact and put in the 200 OK below Or 3. Should I handcraft a REFER message and send to caller instead? Please advise. Config section: sl_send_reply("100", "Trying"); sl_send_reply("180", "Ringing"); append_to_reply("Record-Route: <sip:MY_PUBLICIP_ADDR:$Rp;lr;nat=yes>\r\n"); pv_printf("$var(sessid)", "s.$(pp).$(var(cnt)).$(RANDOM)"); $var(rbody) = "v=0\r\n"; $var(rbody) = $var(rbody) + "o=- 3688213899 3688213900 IN IP4 MY_IP_ADDR\r\n"; $var(rbody) = $var(rbody) + "s=Kamailio\r\n"; $var(rbody) = $var(rbody) + "t=0 0\r\n"; $var(rbody) = $var(rbody) + "m=message 2855 TCP/TLS/MSRP *\r\n"; $var(rbody) = $var(rbody) + "c=IN IP4 MY_IP_ADDR\r\n"; $var(rbody) = $var(rbody) + "a=path:msrps://MY_IP_ADDR:MY_MSRP_PORT/" + $var(sessid) + ";tcp\r\n"; $var(rbody) = $var(rbody) + "a=accept-types:message/cpim text/* image/* application/im-iscomposing+xml\r\n"; $var(rbody) = $var(rbody) + "a=accept-wrapped-types:text/* image/* application/im-iscomposing+xml\r\n"; $var(rbody) = $var(rbody) + "a=setup:passive\r\n"; set_reply_body("$var(rbody)", "application/sdp"); sl_send_reply("200", "OK"); Thanks Pranathi From: Daniel-Constantin Mierla [mailto:miconda@gmail.com] Sent: Friday, May 05, 2017 2:43 AM To: Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt;rg>; Pranathi Venkatayogi &lt;pvenkatayogi(a)cyracom.com&gt; Subject: Re: [SR-Users] How does dlg_bridge work? Hello, is the dialog already answered at that time? Can you see it via kamcmd dlg.list ?

I have a TEXT call from cust1@somedomain to Kamailio. I have an agent who is logged in, but is not in any call yet. I want now refer cust1@somedomain to talk to agent directly. How do I do that? I tried - dlg_bridge("$dlg(from_contact)", "$var(agentSipAddress)",""); I get an “audio call” from “Kamailio” to customer, but nothing happens on the agent side. I tried “dlg_refer” as well but nothing happens at all. Should I handcraft “Refer” message using uac module and send to “customer” instead? Please suggest.
