[Serusers] 2 quick questions
by Nick Hoffman 30 Mar '06

30 Mar '06

Hey guys, I just have 2 quick questions: If ser is running and dealing with 500+ registered users, would doing a ``serctl ul show USERNAME'' add a significant amount of load the box? Using serctl, how do you determine if a given user exists within ser? ``serctl ul show USERNAME'' only shows "in-RAM online users", so won't necessarily show an existing, offline user...

[Serusers] Rejecting FAX
by Jean-Michel Hiver 30 Mar '06

30 Mar '06

Hi List, Is there a way to configure SER to properly reject T.38 FAX calls (with a "circuit fast-busy" or something)? I have tried to google for this but haven't found anything. Cheers, Jean-Michel. -- Jean-Michel Hiver - http://ykoz.net/ Découvrez la Réunion des Technologies IP & Telecom TEL: +262 (0)262 55 03 98 - RCS 434 273 330 SAINT PIERRE

Carlos, Use ngrep -W byline -d any port 5060, to see only SIP packets. To also view RTP use: ngrep -W byline -d any port not 22. Port 22 (the irrelevant packets) are the ssh packets.

RE: [Users] OpenSER MySQL Updates - Weird
by Douglas Garstang 29 Mar '06

29 Mar '06

Norman/Bogdan, I went and implemented three location tables in MySQL and pointed each OpenSER to a different one. I think this is going to have problems... Say a phone registers with proxy1, and proxy1 updates location table location_proxy1. I see two problems here: a) Based on the expiry in location_proxy1, proxy1 removes the phone from it's location table location_proxy1. At about the same time, the phone re-registers, and this time registers with proxy2 (our phones use DNS SRV). For some small amount of time, the phone could be present in TWO location tables. This is bad. b) The phone re-registers before the expiry in location_proxy1 occurs, lets say because it's been rebooted. When the phone comes back up and re-registers, it regisers with proxy2 this time (again because of DNS SRV). For possibly a very LONG time, the phone will be current in two location tables on 2 proxy servers. If the phone was rebooted again, it could be present in the location table on THREE proxy servers. This is also bad. > -----Original Message----- > From: Norman Brandinger [mailto:norm@goes.com] > Sent: Tuesday, March 28, 2006 12:41 PM > To: Douglas Garstang > Cc: Bogdan-Andrei Iancu; users(a)openser.org > Subject: Re: [Users] OpenSER MySQL Updates - Weird > > > Douglas, > > Below is Bogdan's previous response to you: > > <snip> > all db_mods from 0 to 2 use mem cache - the difference is > when the DB is > updated with changes from cache. in mod 1 the changes from cache are > immediately written into DB. > > the only non-cache db mod is 3, but this is available only in > the devel > branch - read carefully the docs to understand the > implications of this mod. > </snip> > > As you can see, he didn't say that db mode 3 is required in your > situation.

Hi everyone, is possibile to configure openser with some trigger that allows it to switch incoming message (INVITE, REQUEST, etc...) towards another element, like an application server? Do they exists? Where can I find it? Thanks for help

[Serusers] Port mapping with Linksys wrt54g
by PREVOT Paul 29 Mar '06

29 Mar '06

Hello, I am using a Linksys wrt54g router that applies Symetric NAT. When I register with my OpenSer proxy, I set my private IP address to Via, Call-ID and Contact fields, because I have enabled fix_nated_contact(); from the nathelper module. There is no problem with the registration. I get the OK back and openserctl ul show returns public IP and public port in Contact field. Also, OpenSer knows an IP:port to use to forward me SIP messages, or small UDP packets to keep the mapping on my NAT alive. To do so, I use modparam("nathelper", "natping_interval", 10). But I noticed that after each SIP transaction the router changes the mapping used. It means Register and OK on port for example 10000 on the router's public interface and the next INVITE-OK-ACK through port 10005, a second INVITE, through other port. So the mapping done for my 5060 port change very often and also as soon as the register transaction is finished, it becomes false and openSer can't send me any Sip Message. There is no problem with MSN or Skype because the signalling is done on TCP. Do you think registration using TCP instead of UDP will fixe the issue? Have you ever come across that issue? Can it be solved out differently? Thanks, Paul
