Hi Stoyan,<br><br>Does that mean that you use Asterisk as pure SIP PSTN Gateways? I imagined Asterisk as a physical PSTN gateway but thought that Kamailio/RTPProxy would scale out better for pure SIP. I was planning to use Asterisk or FreeSWITCH as a media server for hold, VM, conference and IVR.<br>

We do just that way - Kamailo to handle load balancing and clients, and Asterisk servers for routing, gateway etc....<div>You can forward calls to your main gateway which then will work with other gateways or calls from gateways to clients registered in Kamailio.<br>

Hi,<br><br>I am just getting started with Kamailio and have been following the book "Building Telephony Systems with OpenSER" by Flavio E. Goncalves. The book describes an architecture with a SIP Proxy handling registrations and handing calls to a PSTN Gateway. I now have a basic test network running where calls are routed via the SIP Proxy (Kamailio) to a third party PSTN Gateway. I feel that a better design would be to implement my own PSTN Gateway using Kamailio. This single gateway would then handle all third party PSTN gateways. Thus one Kamailio server would be facing my clients while another would be facing my suppliers.<br>
<br>Is this a sensible architecture and are there any sample configurations for Kamailio performing this role?<br><br>Thanks<span><font color="#888888"><br>Rob Watkin<br><br><br>
