Hello, I am trying to build the following setup using OpenSIPS load balancer and the proxy functionality:
Client 1 (sipp) <----> OpenSIPS Load Balancer <----> OpenSIPS Proxy <----> Client 2 (sipp) At the client ends I am using the following commands: Client 1: sipp -sn uac -rsa [Load Balancer Address] [Client 2 Address] Client 2: sipp -sn uas The Load Balancer is configured with a destination as the OpenSIPS Proxy and the Proxy is configured to simply forward the SIP messages based on IP address (using only forward(); in the routing block). Now everything (INVITE, OK and ACK messages) works fine except the BYE messages that are getting forwarded by the Load Balancer directly to Client 2 unlike the INVITE, OK and ACK messages that traverse the Proxy. Client 2 however, sends the OK to the BYE to the OpenSIPS Proxy. Since the BYE messages do not traverse the Proxy, the OK to the BYE messages are getting retransmitted repeatedly by Client 2 and the sessions are not getting terminated properly. How do I make the BYE messages to go through the Proxy or the OK message sent directly to the Load Balancer so that the retransmissions do not happen and the sessions get terminated properly? [NB: When the Load Balancer is taken out of the loop and the Proxy configuration is kept the same, all the SIP messages traverses the Proxy and everything works fine i.e., the BYE and the OKs to the BYEs are handled properly and sessions get terminated properly.] Would greatly appreciate any help in this matter. Thanks in advance. Nil.
