Hey guys,
I'm trying to plan a deployment for a couple thousands of users. As we are
facing now some issues for scaling, I'd like to make a modular architecture
in order to add a server when needed.
I was thinking about N+1 Kamailio Proxies to Register customers and handle
the border of the network, 1+1 Redirect servers so internal Network
Elements can "find" the right Proxy to terminate a call. Customers would
use DNS SRV to decide which Proxy to send a REGISTER and then send INVITES
to that same proxy.
As we have a private core network addressing, I'm thinking I'll have an
Asterisk farm in order to perform media handling.
Do you have some recommendation or guidelines for this deployment?
Thanks!
Uriel

SRV may be troublesome if customers can use any SIP clients. Some SIP
clients really have a strange SRV implementation (eg. some make SRV
lookup for every request, thus reREGISTER can end up at another proxy).

Klaus

Kamailio for example :=) When routing a register request via kamailio with SRV
enabled, it will do a lookup for each request. That's a problem when you
receive a 401 to the first registration attempt.

Sorry. It would do a single request if caching is on, but as it's not dialog
aware, the second register can end up in another server.
