Hi,
/* uncomment and configure the following line if you want Kamailio to
* bind on a specific interface/port/proto (default bind on all available) */
# listen=udp:10.0.0.10:5060
mhomed=1
even this config is the same. I do not bind on specific interface since doc says that if
there is no listen, kamailio will bind on all interfaces…
strange thing… if I explicitly set listeners for tcp and udp on all IP addresses it
works!
I have a dozen kamailios out there, all in mhomed=1 config. On every single one double_rr
works without setting any listen parameters, only on this particular one machine in a
separate datacenter it didn’t work.
Thanks for the hint!

Does Kamailio have listeners (listen= on both interfaces)? What is the value of the
‘mhomed’ setting?
These nuances surely differ between the two hosts.

I’m experiencing issues with kamailio 5.1 in multihomed config:
two machines, latest debian stretch, latest kamailio 5.1, exactly same config (verified
with diff)
both machines have an internal and an external network interface. Only thing different is
that they are in different datacenters.
on one machine everything works perfect, on outgoning calls rr parameters are added
perfectly right:
Record-Route: <sip:yy.yy.yy.yy;transport=tcp;r2=on;lr;nat=yes>
Record-Route: <sip:xx.xx.xx.xx;transport=tcp;r2=on;lr;nat=yes>
where yy.yy.yy.yy is the external ip and xx.xx.xx.xx is the internal IP
on the other machine I only get:
Record-Route: <sip:xx.xx.xx.xx;transport=tcp;lr;nat=yes>
even if I set enable_double_rr to 2 I get:
Record-Route: <sip:xx.xx.xx.xx;transport=tcp;r2=on;lr;nat=yes>
Record-Route: <sip:xx.xx.xx.xx;transport=tcp;r2=on;lr;nat=yes>
I already checked with traceroute that the routing to the destination IP Adresses are
going through the external interface.
maybe someone has a hint for me.
Thank you all in advance!
