[Serusers] Saving SIP-Method as text

[Serusers] rtpproxy options

by harry gaillac

Hello, I need help to understand ser+rtpproxy. How may I configure rtpproxy options to run with ser/nathelper on the same box ? rttproxy options : usage: rtpproxy [-2fv] [-l addr1[/addr2]] [-6 addr1[/addr2]] [-s path] [-t tos] [-r rdir [-S sdir]] SER communicated with RTPPROXY via unix socket. Does RTPPROXY rewrite INVITE/REGISTER message with info from SER? private-------FW+NAT------SER+RTPPROXY------ public network network which ports must be opened on FW box for INVITE and/or REGISTER methods are they the same than on rtpproxy ?

Re: [Serusers] still no help - usrloc synchronization

by Java Rockx

Alex, How does a forking proxy help when dealing with virtual IP addresses? Perhaps I don't quite understand what you mean by a "forking proxy" but it appears you'd have one "main" proxy that basically hands off requests to others? Right? If so, what happens if the "main" proxy crashes? All customers experience a service outage. LVS is a very valid approach to achieving 99.999% uptime from a service perspective.

Re: [Serusers] more usrloc synchronization

by Tina

Hello there, see my comments inside. KRs, Tina "Greger V. Teigre" <greger(a)teigre.com> wrote: > Greger, thanks a lot. > The problem with load balancer is that replies goes to the wrong > server due to rewriting outgoing a.b.c.d . BTW, as Paul pointed, if > you define some dummy interface with Virtual IP (VIP), there is no > need to rewrite outgoing messages (I tested this a little). Yes, if you use LVS with direct routing or tunneling, that is what you experience. ===Of course. That why I implemented small "session" stickness. However, it causes additional internal traffic. What I described was a "generic" SIP-aware load balancer where SIP messages would be rewritten and stickiness implemented based on ex. UA IP address (or call-id like vovida's load balancer). ====Sure, it's better solution; I think we'll go this way soon (in our next version). > Why DNS approach is bad (except restricted NAT - let's say I am > solving this)? Well, IMO, DNS SRV in itself is not bad. It's just that many user clients do not support DNS SRV yet. Except that, I like the concept and it will give you a geographical redundancy and load balancing. ===I am trying to build the following architecture: DNS (returns domain's public IP)->LVS+tunneling (Virtual IP)->ser clusters (with private IPs) | | DB (MySQL 4.1 cluster) > I guess, Paul utilizes load-balancer scenario you have described. > Believe there are only proprietary solutions for > "the-replies-problem". We tried Vovida call-id-persistence package, > unfortunately it didn't work for us. Are you referring to the load balancer proxy? IMHO, the SIP-aware load balancer makes things a bit messy. It sounds to me that the LVS + tunneling/direct routing + virtual IP on dummy adapter is a better solution. > In my configuration I use shared remote DB cluster (with > replication). Each ser see it as one-public-IP (exactly the approach > you named for SIP).

Additional problem - it still doesn't solve usrloc > synchronization - you still have to use t_replicate()... I'm not sure if I understand. ===Oh, probably I expressed myself not well enough... So, you have 2 servers at two location, each location with a shared DB and then replication across an IPsec tunnel?? IMHO, mysql 3.23.x two-way replication is quite shaky and dangerous to rely on. With no locking, you will easily get overwrites and you have to be very sure that your application doesn't mess up the DB. I haven't looked at mysql 4.1 clustering, but from the little I have seen, it looks good. Is that what you use? ===We have 2 or more servers with MysQL 4.1 virtual server (clusters balanced by LVS). We use MySQL for maintaining subscribers' accounts, not for location. User location is still in-memory only so far. I am afraid I have to switch to ser 09 in order to use save_memory (thanks Paul!) and forward_tcp() for replication. > With regard to t_replicate() - it doesn't work for more than 2 > servers, so I used exactly forward_tcp() and save_noreply() (you're > absolutely right - this works fine so far); all sers are happy. Of > course, this causes additional traffic. Interesting whether Paul's > FIFO patch reduces traffic between sers? I believe Paul uses forward_tcp() and save_memory() to save the location to the replicated server's memory, while the save("location") on the primary server will store to the DB (which then replicates on the DB level). g-) --------------------------------- Do you Yahoo!?

[Serusers] SER 0.8 to 0.9: check_to and check_from gone from URI module?

by Cameron Beattie

I have just downloaded and installed SER 0.9 and note that the URI module doesn't include the check_to and check_from functions any more. I look at the readme file of the uri module and it only includes the is_user and does_uri_exist functions. But I've seen them referred to in the documentation from onsip.org which uses 0.9. Does anyone know if these functions have been replaced with something else or whether I've done something wrong? Regards Cameron
