Hello,
I hope this is the right forum to post a request for consulting services. We have a requirement for setting up a HA OpenSIPS 1.4.2 installation with a primary (active) and secondary (failover) server running CentOS 5.x. SIP messages from the active server must come from a virtual IP address and carrier gateways receiving our call traffic must remain oblivious to any server failure. Failover must occur in < 5 seconds.
We would like to see a simple solution based on open source components like vrrp or Linux-HA, including the SIP heartbeat mechanism and failover per se, as well as the recovery process once the primary server recovers from the failure causes. The work will be done in conjunction with our Linux Administrator and IP Telephony Engineer and must be documented, at least in a basic fashion. Failover testing under load will be performed prior to project acceptance.
If you are an expert in OpenSER HA implementations and are interested to help us, please respond via this forum or directly to my e-mail address, serge A T elasticall D O T com. Thanks in advance.
Best Regards,
Serge
