parallel fork of calls with same Call-ID #39
Comments
Closing as this is already being handled on the kamailio mailing list |
Hello ! I would like to know if this issue is solved sipwise/mediaproxy-ng#23 My test is very simple, I have 2 endpoints connecting to the same username (201). One using TLS/SRTP, the other one using UDP/RTP. If I call 201, the 2 endpoints ring but I can see that rtpengine overwrites the offer of the other one. And finally got this error: "SRTP output wanted, but no crypto suite was negotiated" I use the kamailio-advanced.cfg provided with default installation of kamailio(4.2.0). And I think lookup(location) doesn't work with rptengine even if modparam("registrar", "append_branches", 1). kamailio seems to reuse same callid and branch value for the 2 calls, so rtpengine can't detect 2 sessions. @ovoshlook, this is why you don't use lookup(location) and build manually the branches ? Thank you ! |
I not use lookup becasue I use WebSocket based endpoints and kamailio can 2014-10-28 1:12 GMT+04:00 GGGO notifications@github.com:

Hello. I try to do parallel fork calls to endpoints that have same username and different destination URI through Kamailio. Logic of my script:
checking location table for rows with needed account
get info from contact at loop
for every step
check technology (sip or ws)
handle call with rtpengine
append_branch with existing destination for this account
rewrite packet with rtpengine to needed technology
after loop
forward packets via t_relay
sql_query("ca", "select contact from location where username='$tU'", "ra");
xlog("rows: $dbr(ra=>rows) cols: $dbr(ra=>cols)\n");
So it customised schema of standart example
seturi("sip:a@example.com");
append_branch("sip:b@example.com");
append_branch("sip:c@example.com");
append_branch("sip:d@example.com");
t_relay();
At my test I have 2 endpoints with WS and UDP phones (at fist step ir WS and 2 step it UDP). when I do these steps (at my script) I see packet at TCP dump and saw that sended only one packet to UDP but body of packet is WS. Then I saw log of kamailio. I see that at second step packet changed body to WS body (so strange because other steps before and after goes for UDP (as at logic of script))
All calls going form asterisk via UDP.
I think my problem may be at rtpengine that already handle packetd with this Call-ID and gives same result for other flags to this packet at second step.
Does it right?
