MultiHomed Setup

[grayco...@gmail.com]

Hi All,. 

Trying to setup multi-homed dsiprouter, but struggling find what dSipRouter config to start with before making adjustments to rtpengine.conf and kamailio.cfg.

Ive tried to installed dSipRouter with 2 nics installed . eth0 = public ip and eth1=internal ip. Vanilla install of debian 9 and dSipRouter was installed using dsiprouter.sh install -all -servernat. The setup completed and installed but only on the public ip address. Ive modifed the kamailio.cfg file  but it still only seems to bind to 1 ip address when i run kamctl srv sockets(but does show the internal ip being aliased with external ip), in fact kamctl srv sockets doesnt show multihomed as enabled either

Just wondering if anyone is able to offer some advice on the initial setup of dSipRouter, Eg Should i start with start with only 1 nic, perform a NAT'ed setup. Shutdown, install 2nd nic, assign Public IP to 2nd nic, then do the mhomed=1 and change external_ip_addr in kamailio.cfg, and make the relevant changes to rtpengine.conf to reflect the new external IP address, Or is there another method to perform a base install of dsiprouter to then make the modifications to allow a multihomed config/?

Thanks in advance.

Quick Update. external calls working, voicemail access etc working but 1 way audio at the moment between endpoints on same interface.

Its worth the time to get "under the hood" of dSipRouter. The more I search the more I become to realise how much dSipRouter is doing behind the scenes - Keep up the good work Mack.

Thanks Grahame,

Multihomed is on our roadmap.  Matt did a great job writing this up.  We just have to make the installer deal with multiple interfaces.

In regards to your issue,  you will need to test if the call is going between two ip’s on the same interface and then invoke the RTPEngine to write the SDP properly proves not rewrite at all.

Do we have that post published anywhere so that he can look at it?  I need to test it on the latest version still.
