In my company there is a Big IP Load Balancer. The current configuration is shown below:
SoftSwitch --> (F5 – Big IP) --> IVR x 5. In this configuration the SIP signaling from the SoftSwitch send a request messages to IVRs through the Big-IP. The answer from the IVRs goes from them to the SoftSwitch without passing back through the Big-IP (asymmetric signaling traffic). I think there is something wrong in this configuration because there is not a topology hiding and exists a security hole. I’d like to confirm that we can configure the Big-IP in order to handle the symmetric traffic from and to the IVR passing through the Big-IP.
SoftSwitch --> (F5 – Big IP) --> IVR x 5.
SoftSwitch <<<---------------------- IVR
SoftSwitch <--> (F5 – Big IP) <--> IVR x 5.
Hi Jesus, Did you get an answer to this question? If not, I have a very similair setup, and we got it working Incoming SIP >> Big-IP >> SIP_Servers >>Big-IP >>Outgoing SIP. Let me know if I can help. matt
