[Serusers] Instant Messaging cannot work with Windows Messenger 5.0
by kokmeng＠moij.biz 20 Sep '05

20 Sep '05

Hi, I have two PCs running Windows Messenger 5.0 and SER as registrar. I am able to get Voice, Video, App Sharing, Whiteboard, Presence (peer to peer only) working. However, I cannot get Instant Messaging to work. When I look at my Ethereal capture, I see that with 5.0, INVITE is used to start an IM session. The other client responds with TRYING, then OK. However, it also sends a BYE immediately after sending the OK. Subsequently when the originating client sends the MESSAGE, the other client responds with an Error because "Call Leg does not exist". Has anyone encountered this before? I've seen this problem being mentioned in Google searches, but no answer so far. Regards, KokMeng Loh

[Serusers] DNS SRV for load balancing
by Peter 19 Sep '05

19 Sep '05

We are trying to use DNS SRV records to load balance outbound transactions across 2 or more servers. Something like this: UA => SER => (Some processing logic) => Back to SER after a 300 Redirect which contains a Contact phone number and IP/DNS at which to contact the contact => DNS SRV lookup for the contact IP and send it to one of the two servers returned by the DNS lookup. So this last leg is where we have to load balance multiple contact IP servers and we were trying to use DNS SRV for that. We haven't seen any success in this, it does load balance when both are up. But as soon as only one server is up, SER keeps trying to reach the first one which is down and never tries to reach the second one. Ultimately the transaction times out. Has anybody had success in implementing this kind of scenario for load balancing with DNS SRV? Is anything else besides using DNS SRV an option? Thanks in advance!! __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

Marcello, Here is one method that I have been looking at - has anyone tried something similar? # --- Rewrite 50/50 -------------------------------- if (uri=~"test") { if (is_gflag("1")) { reset_gflag("1"); rewriteuri("sip:test@10.1.1.1"); } else { set_gflag("1"); rewriteuri("sip:vsd@10.1.1.2"); }; t_on_failure("1"); } # -------------------------------------------------- Thanks, John Rose -----Original Message----- From: serusers-bounces(a)iptel.org [mailto:serusers-bounces@lists.iptel.org] On Behalf Of Marcello Lupo Sent: Saturday, September 17, 2005 7:38 AM To: serusers(a)lists.iptel.org Subject: [Serusers] SER Load balancing Hi to all, did you have suggestions how to accomplish to load balancing load of SER between 2 machine running both SER and DB to check routing entries?? I was thinking to use LVM but i don't know how to let the same call messages to go to the same machine. There should be something line an LVM module able to check the CallID field and keep track of it. May be some other ways?? Using DNS records or other? Another question is if there is a searchable archive of this Mailing list. Thanks, Bye, Marcello _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers

How can SER be made to look for the MySQL socket file in /var/run/mysql/mysql.sock instead of /var/lib/mysql/mysql.sock? Paul

Hi, I notice that ser ignores all "REGISTER"s that come from a special server with the port 5060. All other ports are accepted. What could be the problem? Sebastian

by John, Paul 19 Sep '05

19 Sep '05

I'm having trouble with MySQL starting when the socket file is located in /var/run/mysql/mysql.sock instead of the default location /var/lib/mysql/mysql.sock. I have changed the owner and permission of the new directory, but I still get the following error in the log. I don't have another mysqld server running on this machine. 050919 12:24:11 [ERROR] Can't start server : Bind on unix socket: Permission denied 050919 12:24:11 [ERROR] Do you already have another mysqld server running on socket: /var/run/mysql/mysql.sock ? 050919 12:24:11 [ERROR] Aborting Paul

[Serusers] avpops and register
by Rodrigue ESTEVE 19 Sep '05

19 Sep '05

Hi, I'm trying to do the following things using the avpops: When I receive a Register Message from uri 666@.., I'd like to register the uri 1000@... and 2000@... at the same time. I'd like to do this also for uri 777, to register 778 and 779 when 777 triggers a Register Message. So I decided to use the SQL Table below to achieve this: Initnumber: Varchar(64) Attribute: Varchar(64) Type: INT (default to 0) Associated: Varchar(64) Initnumber attribute type associated 666 register 0 1000 666 register 0 2000 777 register 0 778 777 register 0 779 In Ser.cfg, I put this: modparam("avpops","avp_url","mysql://ser:heslo@IP/telephone") modparam("avpops", "avp_table", "associate") modparam("avpops","username_column","initnumber") modparam("avpops","attribute_column","attribute") modparam("avpops","type_column","type") modparam("avpops","value_column","associated") if (method=="REGISTER") { # Authentication Challenge Challenge #Test of AVPs log(1, "LOG: AVP REGISTRATION"); avp_db_load("$from ","s:register"); #to display avp in memory avp_print(); #fork registration using new avp value to register avp_pushto("$from","s:register/g"); save("location"); break; }; What I expect this to do is to get the values "associated" with "Initnumber", using avp_db_load and to fork the registration process using avp_pushto to register the numbers in the associated column. I use avp_print to see the avp loaded in memory, but I see nothing in the syslog. Moreover nothing happens, ie only the uri which initiates the Register message is registered on SER :'( Can somebody help me please, Rodrigue

by Nhadie 19 Sep '05

19 Sep '05

Hi List, Don't know if this is the right list for this but I hope someone can help me: I have a SIP server when it starts on a certain string e.g. 123 it will forward it to gateway else it will forward to gateway 2. Gateway 1 will be a cisco 1760 with and FXO port, so whe I dial 12345678 it should forwar it to the Cisco 1760, using ngep I can see that it's sending the invite to the CISCO 1760 but I don't know what typre of dial-pper to define in order for th 1760 to respond, also what typre of dial-peer would forward it to the FXO port and eventually call PSTN. TIA Regards, nhadie
