I have installed kamailio as a ims server in openstack and enabled WITH_NAT
and rtpproxy . I have installed pcscf, icscf, scscf and hss in four
different ubuntu instances .

server - kamailio 5.3.3.

When i make a call using zoiper client from external network , call is
becoming a missed call without giving ACK and BYE.

Openstack -
pcscf - (floating ip -
icscf -
scscf -
hss -
zoiper1 -
zoiper2 -

kindly help me in this regard.

when i installed without using NAT and rtpproxy, the call went well. Since
currently i am using Opensatck , it is my prerequisite to use zoiper client
externally .so for me it is mandate to enable NAT and rtpproxy.

Help me please!!!
