SIP SLB and Call Persistence using ServerIron ADX
1
FIGURE 5 SIP Server Load Balancing with ServerIron non-DSR mode
To maintain session persistence and transaction integrity, this implementation has the following
requirements:
The SIP proxy server should use same call-ID for both legs of communication (for example, for
message exchange with both SIP clients within a given SIP dialog).
For all outbound SIP communications, the proxy server should use the same UDP/TCP source
port as that used as the destination port for all inbound communications.
NOTE
If the proxy server uses a source port other than the one used as the destination port for inbound
communications, then these packets arriving from proxy server go untranslated by the ServerIron.
The proxy server IP address must be reachable from all SIP clients in such cases.
