Hello All, new subscriber here.
I've been reading kamailio documentation to check if kamailio has a use case on the
architecture for the solution for my company's software, here an small architecture
diagram of our solution.
sipclient <----> [ Middleware ] <-----> SBC
Our middle ware is both a sip proxy and media proxy. we have a large number of sip clients
but a small calling number,
our current bottleneck is that the middleware can't handle a high number of
registration, i would like to deploy Kamailio as a load balancer for registrations, making
sure it is statefull so registrations and calls are hashed into the same middleware
server.
sipclients < ----> [ kamailio ] <------> [ middleware1,
middleware2,...,middleware N] <-----> SBC
Any thoughts or pointers?

Hello,
this looks like a typical load-balancer scenario, well supported from Kamailio. Have a
look e.g. to the dispatcher module documentation, you'll find also some examples at
the bottom of the docs.
Cheers,
Henning

You want to look at the dispatcher module that can dispatch based on hashes.

assuming the middleware is the registrar server, if it support the Path
header extension for SIP, the it should be simple, in kamailio side you
can use dispatcher module for load balancing and path module to add Path
headers to REGISTER requests.
If the registrar does not support Path, then you need to mangle the
contacts in order to ensure that traffic towards sipclients go through
kamailio, so NAT traversal can be ensured. Doable, but with some extra
operations done in kamailio config.
Cheers,
Daniel
