[OpenSIPS-Users] Is opensips a front end to asterisk?

Hi

thats very big project., for that you need to study the system indepth both
Opensips and Asterisk

at this moment iam working on the same project but my concept is

Opensips -- Registrar and Proxy and hand NAT with rtpproxy
for this Opensips can handle as many as users depends on the hardware and
design of network

use Dispatcher to loadbalance across Asterisk PSTN Round Robin basis

If you can Route X amount of calls to * 1 and * 2  Y amount of calls

use LB modules.


2 Opensips ( for loadbalance registration) replicate
1 Mysql Server
3 Asterisk for PSTN  / VoIP handling


Hope this helps to start with.
