[SR-Users] Kamailio B2BUA or Dual router ?

Yes I understand that with 2 interfaces, but I am looking for 1 interface
with multiple IP’s (ipv4) assigned to that interface, can’t seem to get the
logic for Kamailio on knowing what in or out depending on IP ?


Basically I have this


SIP Client             ßà      Kamailio Proxy w/RTpproxy
ßà      Asterisk                          external/internal


So I need traversal and translation over same interface in both directions ?
(seems like a b2bua, but only need load-balancer for this scenario)



Hilsen / Regards

yes, you can use kamailio to bridge between two interfaces, an example is:


You need rtpproxy or rtpengine to bridge the media as well -- for rtpproxy,
there is an rather old but still good to look at example in source tree:


On AWS, you may need to declare 'advertise' property to listen parameters
(see core cookbook in kamailio.org/wiki/).

Hello All


I have been looking for answers and trying really hard to figure out if I
can use Kamailio as a Dual Router (Inbound and Outbound using 2 IPs on 1 Eth
“Amazon AWS”)


I can not seem to find information is this is possible using Kamailio or if
am just plain “stupid” and can not read the Wiki well enough J


Hope you can help
