[Serusers] Commercial loadbalancer, NATed clients and src port problems
by George Perantinos 24 Oct '05

24 Oct '05

Hello list. My setup consists of two SER servers behind an F5 Big-IP for load balancing. The servers are "pooled" behind a virtual server (i.e. they present a common IP address to the rest of the world) created at the Big-IP and I'm using call-id persistence. My ser.cfgs are slightly modified mediaproxy examples from onsip.org. Each SER replicates to the other REGISTER messages, so that both servers are the same. So far so good. Suppose that NATed UAC1 is registered at SER1 (SER1 is sending the 4 byte udp packet every 60sec in order to keep its NAT binding open) and UAC2 sends him an INVITE: 1) If the INVITE gets served by SER1 everything is OK. 2) If the INVITE gets served by SER2 then: a) SER2 sends the message from port 5060, b) but the packet arrives at UAC1 with source port 5061 (or 5062 or whatever). This means that for some reason the Big-IP changes the source port it receives from SER2 to something other and, of course, the packet does not pass UAC1's NAT binding. So, the conclusion is that a UAC is only reachable through the SER that keeps it's NAT binding open. In order to solve this problem (and until SER can support path headers) I employed the method and the patch discussed at http://lists.iptel.org/pipermail/serdev/2005-September/005814.html (thanx for the patch Evan). I have to admit that this system was my first experience with a Big-IP, so I'm wondering: Am I doing something wrong at the Big-IP? Or is this Big-IP behavior (altering source ports received from internal servers) typical to every (even commercial) load balancer? Has anyone ever had success with any load balancer, multiple SERs and NATed clients, especially F5s? Regards, George

When you process the incoming: INVITE dsandras aT gnome.org and reaches lookup("aliases");, the Req-URI will be AUTOMATICALLY rewritten to have: INVITE 6001 aT gnome.org Isn't this what you want???? You don't need rewriteuri for anything, lookup will do the job for you. Samuel.

In the lines: # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line modparam("usrloc", "db_mode", 2) you select the mode you want to use the database. If you put 2, the "records" added to SER via serctl will be propagated to the permanent database not immediately but periodically. I think this periodicity can not be set in the config file. If you use 1, all records inserted with serctl will immediately be written also to the database. So I guess you don't see the changes immediately and think that there is a problem....either wait more or put 1 to the dbmode to check if there is a problem with the database. Samuel.

[Users] Call Forwarding using uac_redirect
by Brandon Price 24 Oct '05

24 Oct '05

I am trying to implement call forwarding using the uac_redirect module. My user agents reply with a SIP 302 Moved Temporarily message when the unconditional call forward is set. In the contact field there is something like this... Contact Binding: <sip:13143212222@ser1.manhattan.sipnetwork.net> I need ser to add a plus to that then send the call back out to our pstn carrier. I have tried this... if (t_check_status("302")) get_redirects("6:2","redirect"); prefix("+"); rewritehost("pstn.carriers.ip"); t_relay(); and putting it in a failure route then forcing that route failure_route[2] { get_redirects("6:2","redirect"); prefix("+"); rewritehost("our.pstn.carriers.ip"); t_relay(); I even tried if (t_check_status("302")){ # what to do if device tells us to forward to another number add_diversion("user-forward"); get_redirects("6:2","redirect"); prefix("+"); rewritehost("our.pstn.carriers.ip"); t_relay(); but apparently get_redirects can only be used in a failure_route Has anyone been able to get this working? On a 302 get the redirects from the contact field using get_redirects append with a "+" and rewritehost somewhere else it seemed so simple. Any help is as always greatly appreciated, especially from daniel(a)voice-system.ro cause like me he's too far for norway beer.
