The call distributor only distributes incoming SIP calls among multiple proxies or may be even SIP UAs (like a SIP-PSTN GW). The SIP-GWs would listen on non-standard ports. The call distributor would receive INVITEs etc on port 5060 and send them to the SIP GW which may be listening on port 10,000. Now, the re-transmitted INVITEs would still come to the call distributor. And also until the SIP GW can give its new contact in the 200 Ok or possibly in an UPDATE, subsequent requets (like PRACK) might come through the call distributor. In such cases, the distributor would need to send the subsequent requests to the same GW (as the first INVITE was sent to). Now, for this purpose, is it enough that the distributor looks at just the Call-Id and not other tags and parameters? Thanks Andy
