I think the uncached version is being released very soon now. It might work in a failover mode, but if one SER server does a REGISTER for UA 1, and another SER instance does UA 2, they overwrite each other in the database. Each instance thinks it has control of the entire location table. That is my understanding however I've been wrong before :-) -g

Did You already take a look at http://www.voip-info.org/wiki-SER+example+redirect ? If You put of Your servers as "Master" (dispatcher) and the others as "slaves", You may only have to concentrate Yourself in one peace of hardware... ;) Edson ----- Original Message ----- From: "Darren Nay" <dnay(a)libertyisp.com> To: <serusers(a)lists.iptel.org> Sent: Monday, February 02, 2004 1:21 PM Subject: [Serusers] Multiple SER Servers Hey All, I have sent this question once before, but I don't believe that I received a response back. If so then I appologize as I must have missed it. Could someone help me out with this? We are gearing up to launch SER on a large scale but I want to verify that I can have multiple SER servers in a primary / failover scenario before doing so. Can I put SER onto multiple servers with load balancing and share the userloc tables between the servers (ie. With MySQL or Postgres SQL) Is this possible? Or does one SER instance only recognize registrations for phones that register with that particular instance/daemon?
