Redirecting traffic - Freeswitch vs Kamailio
If I want to set up a SIP redirector for small call volumes (eg. <1/second), can Freeswitch do as good a job as Kamailio? The idea is that we get a call in from a PSTN-SIP gateway and then re-route to another box depending on the number being called. Just wondering if there's any difference in the signalling, which I presume is either a 302 or a SIP re-invite (but please correct me if I'm wrong!). At what kind of call volumes might one choose to switch to a more dedicated SIP proxy?

Either piece of software can send redirects, but Kamailio is a more natural fit for that sort of thing. -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/
I agree with Alex but a while back I demonstrated using mod_lcr and redirect (issuing 300/302) doing at least 300 cps. I was impressed with the flexibility of mod_lcr (my DB guys loved the custom query support) and the performance of FS in this case. YMMV.

At what kind of call volumes might one choose to switch to a more dedicated SIP proxy? A proper question of volume would be not about good traffic, but about all the traffic, which is a matter of whether the system is on the public net or not and then can face d/dos attacks. A proxy could be the solution for a lightweight SIP firewall in this case, even when the main routing logic is in a b2bua.
