Excuse for troubling i'm using sippy with kamailio. There is option for this:
r - flags that IP address in SDP should be trusted. Without this flag, rtpproxy ignores address in the SDP and uses source address of the SIP message as media address which is passed to the RTP proxy.
from rtpproxy.
so only one moment.
is this ok without trusted SDP flag: "If calling party send some RTP to sippy, then sippy switched to rtp_ip:rtp_port and all is fine (just some start RTP are dropped)."
from rtpproxy.
Hi, some logs to understand that scenario would be helpful. Thanks!
from rtpproxy.
SipPoint1 -> Kamailio+Syppy_proxy -> FreeSwitch -> Kamailio+Sippy_proxy -> SipPoint2
INVITE from SipPoint1 with diffrent IPv4 in SIP and SDP part (SIP ip is the source address of the message, SDP ip is some else public IPv4 address)
in kamailio.cfg
rtpproxy_manage("co");
After ACK SipPoint1 and SipPoint2 have two-way media throw the chan "SipPoint1 -> Kamailio+Syppy_proxy -> FreeSwitch -> Kamailio+Sippy_proxy -> SipPoint2", but the "r" flag is not enabled. (http://www.kamailio.org/docs/modules/devel/modules/rtpproxy.html r - flags that IP address in SDP should be trusted. Without this flag, rtpproxy ignores address in the SDP and uses source address of the SIP message as media address which is passed to the RTP proxy.)
May be it is the Kamailio RTPPROXY module issue.
