Hi Christoph,
so you have an trusted connection "SIPTRUNK" to kamailio (and then
dispatcher to application/freeswitch B2BUA).
I would create an now an vice-versa flow in your kamailio like this:
FreeSWITCH (bridge/internal/kamailio-ip) to kamailio to SIPTRUNK.
Kind regards
Karsten

Hi all,
im currently trying to add a Outbound Proxying to our system
which right
now does inbound loadbalancing for our
application servers.
Current:
Inbound SIP Trunk -> Kamailio -> dispatcher -> ApplicationServer 1..n
i now want to add the ability for our internal Application
Servers to
terminate their outbound calls through the
kamailio system.
currently i've setup a gateway in the (freeswitch) application
server
that has the kamailio system set as
outbound-proxy. this leads to
sip
calls started with
originate sofia/gateway/kamailio/<number>@<outbound carrier IP>
to be sent to the kamailio system which then forwards it to the
given
carrier IP. Sadly our main carrier answers with
"503 service
unavailable
- no bandwith available". (maybe due to the
internal ip-addresses
within
some of the headers?)
i've attached our current kamailio configuration and also a pcap
of a
call i tried to start with our main carrier.
i tried this way as it seemed to be the easiest way so our
application
servers still can select the outbound carrier
within their flow.
maybe i'm on the wrong way here and need to solve this problem in a
completely different way i don't know.
TLDR: sip proxying does not work as expected. need a way to achieve
outbound calls routed through kamailio from internal application
servers
any hint/help into the right direction is appreciated
Best Regards
Christoph Russow
