scalability - How is SIP scaled for high load? -

basically, want implement voip scheme sip in vps server. seems not able handle more ~20 simultaneous calls(just bare sip). workarounds problem? can sip server used database tell clients find intended targets..? p2p? quite new sip. additional info appreciated.

sip scalability comes delegating much work endpoints , doing little on servers possible. describe "redirect server": accepts , stores registrations endpoints (softphones, hardphones, etc), , responds "3xx redirect" incoming calls , forgets them immediately.

this extreme illustration of server minimization. sip versatile protocol, lets set server infrastructure in many different ways varying grade of command on calls. lets trade off features performance.

even flimsiest vps should able handle signalling way more 20 parallel calls in total "stateful proxy" mode.

just create sure media (the rtp streams) not routed through server. set stun help firewalled endpoints send media each other directly.
