I have a SER 0.9.7-pre3 system which is working fine except for call transfers. It turns out that when the NOTIFY is sent after the REFER method the proxy performs a queried for only A records not SRV. This results in an IP address being returned which is a non-SIP host. This is because the domain name is being used by different services some of which use A records for resolving the name and some, like SIP, are suppose to use SRV. How can I make this version of SER perform an SRV lookup instead of an A record lookup when initiating SIP messages? Thanks, Steve

[OpenSER-Users] OpenSer and sip calls

by kriko

Hi! I'm trying to get openser working properly - it starts up, I can even regiter from softphone (linphone / twinkle) but I cannot make calls. OpenSer is running on 10.99.8.103:5060 (this is my machine, IP is bound to eth0), when I try to call to e.g.: sip:demovoice@10.99.8.48 I get some errors as in this log: http://files.myopera.com/kriko/code/openser.tar.gz Configuration is included too. Softphone clients are properly configured - it is the proxy that is causing me problems. Any kind of information is appreciated. -- kriko

[OpenSER-Users] Thoughts on openSER + Asterisk scenarios

by Gabriel Ortiz Lour

Hi all, We are working here on a solution for a large scale VoIP system to cover our entire state, using both openSER and Asterisk. The project is on an initial stage, basically deciding architecture, so I would like to share our thoughts here in the mailing list and hopefully get some feedback to get starting on the right foot. We have our own private network (internet only on a further first step, no NAT), and we think about two possible scenarios: 1: The SIP accounts would register on the local Asterisk and those would talk to a SER core to connect them all, something like "Asterisk: Oh! this account is not mine so I'll send it to the core to take care for me" and the SER core would try to reach the other endpoint or return some error code. 2: All SIP accounts would be registered on the SER core, using the local asterisk servers as mediaservers and backup SIP proxies, where the SIP accounts would be registering on them only when there is some problem on the link with the SER core (and here they would have to have their own local PSTN gateways) This is the two basic ideas, so we would like to have any thoughts about the "pros and cons" of them. We have also planned many PSTN gateways that would be used for LCR (making all PSTN calls = local) for the entire system, that should be considered on a failure event. Thanks, Gabriel Ortiz PS.: Any help/thoughts are very welcome, as we will share all the experience and development on this project with the FOSS community. We are a government IT company from Paraná, Brasil aligned with the Free Software movement, and the aim is to document and package every aspect of this project.

Re: [OpenSER-Users] [openser 1.3] loading module auth.so stop my server (bug?!)

by Pascal Maugeri

I'm still troubleshooting this issue and this morning I added more outputs in the source code of auth_mod.c. And I discovered: 1) when I set the configuration parameter "secret" of the module auth (modparam("auth", "secret", "secretphrase) ) in openser.cfg everything works fine ! 2) when I remove the configuration parameter "secret", the auth_mod.c calls the method generate_random_secret() as stated in the documentation. It enters in the loop for(i = 0; i < RAND_SECRET_LEN; i++) { LM_INFO("(3a)\n"); sec_rand[i] = 32 + (int)(95.0 * rand() / (RAND_MAX + 1.0)); } LM_INFO("(4)\n"); but never exit ! This is the reason why my server does not start and keeps blocked there. I modified the code above to print more logs, I can see in the logs the string (3a) once but I never (4): IMHO it is blocked somewhere in the first random computation. I'm running openser on Redhat Enterprise v4. Is there anything else I should configure in my environment ? Or I found a bug ?

Re: [OpenSER-Users] Specifying IP Address for SIP Responses

by Bogdan-Andrei Iancu

Hi Victor, if a UAC wants to have asymmetric signalling, just send from IP_A:PORT_A and put in top most via IP_B:PORT_B - via is used for routing back the reply. regards, Bogdan Victor Cartes wrote: > Thanks, Iñaki.

[Serusers] Adding authentication through mySQL

by frq ser

Hi, I am trying to add user authentication through mySQL database to my SER (0.9.7-pre1). When I tried to run SER with the modifed ser.cfg file, it gave the error that it could not locate the 'mysql.so' module. Then I tried to 'make' the mysql module following the instructions given here: http://www.iptel.org/faq/why_does_ser_fail_to_start_with_an_error_load_modu… When I typed 'make modules=modules/mysql modules' at the SER source directory, it gives me the error message saying that it could not locate 'mysql.h' and 'errmsg.h' (complete log given at the end of this email). I've tried to locate these files on my computer but couldn't find them. Note that mySQL is working fine on its own. I need your suggestions as to how I should proceed. Thanks in advance for any help.

It is about another feature - notifications about whether the user has voice mail messages pending. Now, since presence does not work for you with xlite, I am wandering if you have clicked the option Show contact availability , or something like this, when editing the buddy details. It is at the end of the form. regards, Anca Vamanu Jeremy McNamara wrote: > Anca Vamanu wrote: > >> Hello, >> >> A major change in the presence structure occurred in openser 1.3.
