Hello, First of all thaks to Kraus for his quick reply on my last question. However I can't do openser work fine. I'm trying to use failure_route as follows, can anybody tell me which could be the problem?? (...) modparam("tm", "fr_inv_timer" , 10) # timer for response to a request modparam("tm","fr_timer", 4) # ------------------------- request routing logic ------------------- # main routing logic route{ (...) if (uri==myself) { (...) # Redirecciono cap a l'asterisk si marquen una extensió que comença per 3 if(uri=~"sip:2[0-9]+@" && method=="INVITE") { t_on_failure("1"); } (...) route(1); } route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; exit; } failure_route[1]{ rewritehostport("172.16.51.160"); #asterisk rewriteuser("2002"); append_branch(); t_relay(); exit; } With this openser.cfg the call is cancelled after fr_inv_timer and failure_route[1] doesn't work but, however, if I do this: route{ (...) if (uri==myself) { (...) # Redirecciono cap a l'asterisk si marquen una extensió que comença per 3 if(uri=~"sip:2[0-9]+@" && method=="INVITE") { à rewritehostport("172.16.51.160"); #asterisk à rewriteuser("2002"); t_relay(); exit; } (...) route(1); } If I use this the call is redirected to my asterisk but using the failure_route as my first openser.cfg it does't work. Which is my problem?? Thanks....

Hi, add ' loadmodule "mysql.so" ' to your config file. Then you must also add a db_url to the module that should use the database, look for example to the usrloc module documentation. A sample setup is described at in the installation notes at: http://www.openser.org/mos/view/-OpenSER-Installation-Notes/ Henning

[Users] General for openser-2 things
by Yago Bargalló 24 May '07

24 May '07

Hello, I'm trying to redirect a call from openser to an Asterisk extension when a call is no answer. I think that this wouldn't be so difficult but I can't do it. I know that I have to use the failure_route(); with a fr_inv_timer parameter and then do a rewritehostport and a rewriteuser. My problem is that when the fr_inv_timer pass the call is cancelled and nothing else happens. In addition, I don't know where I can find the logs that I put in my openser.cfg, I have read the xlog module but I can't understand how to do it. On other hand, I have seen that there are a lot of functions that are often used but I don't know what they do internally, for example t_relay(), t_onreply(), revert_uri(),t_was_cancelled() etc etc etc and I don't know how to use it. ¿Is there any document that explain all it WELL?? Also, I've checked that if I do a call and I put the lines t_relay() and exit that call works fine but if I erase one of the two lines it don't work. Why??? Please help, I want to do a lot of things with openser but there is nothing that explain the basic functionality to do interessant things... Thanks in advance, "It will arrive the day that we will control telephony"

So the traffic from SER to asterisk doesn't need to leave the box. This is why I'm using the loopback interface - there's no need to use the real world one. -- Regards, John Breen HGA IT&T Solutions Tel: 08 63113000 Fax: 08 63113144 http://www.hgait.net.au Level 9, 256 Adelaide Terrace, Perth, WA 6000 Postal PO Box 3133 Perth, Adelaide Tce WA 6832 The information in this E-mail is confidential.

[Serusers] Frustrating error - please help
by Mahatma Sarasvati 24 May '07

24 May '07

Hi All, This ser installation was working fine and I can't figure out why its not working now. I'm getting an error (see last log line) every time I attempt a call to local users. Calling out to PSTN works great. ngrep reveals that SER is not sending any messages to the callee location. There are 2 registered local users, one registered twice. I have no idea what is going on. I'm using an unmodified version 1.4 ser.cfg file on CentOS 5. I suspect some server configuration error? ? ? ? Thanks, M Here are the logs.

[Serusers] Ser + Asterisk on the same box??
by John Breen 24 May '07

24 May '07

Ok, let me see if I've got this right. I'm running SER and Asterisk on the same box. SER listens on the external IP of the box on port 5060, Asterisk on localhost (127.0.0.1) on port 5061. My starting point to get calls from SER able to use the real world is the SER PSTN gateway in the Getting Started document, with route[5] changed to: route[5] { rewritehostport("127.0.0.1:5061"); avp_write("i:45", "inv_timeout"); route(1); } I start SER and add accounts 306, 307 and 499. So far so good, and when I get it all up and running, SIP phones can call other SIP phones via SER. Now, if I read right, I then need to tell SER that 127.0.0.1 is a trusted account by doing INSERT INTO trusted VALUES('127.0.0.1', 'any', '^sip:.*$'); in mysql, and restarting SER. I can still dial between internal phones and that is all OK, but I cannot dial via asterisk. I don't even see calls getting there. If I then add into the trusted table the IP addresses of SIP clients, I can dial from them via asterisk. But I have to do this for every client. This is fine if there are only a limited number of IP addresses that can use the asterisk gateway, but I have users with laptops in the real world whose IP addresses change so it's obviously not an ideal solution. What am I missing? Is the Call Forwarding setup the answer? I need to use SER as a front end to asterisk because of NAT issues, but I don't want to have to add EVERY user to the trusted table individually.

[Users] CPU load, ERROR: append_branch: max nr of branches exceeded, etc..
by Dan Mechanic 24 May '07

24 May '07

Forgive me if this question is a little open-ended... I am new to openser and sip, and trying to learn all I can... I am looking for information regarding: ERROR: append_branch: max nr of branches exceeded I understand that this error can be avoided by increasing the value of MAX_BRANCHES and recompiling openser, but, I am curious as to what happens when this error has been reached. Here's our situation... We use openser, and have a separate openser presence server. We had a situation recently where it seemed our presence server was bombarding our proxy to the point where the load on the proxy jumped and phones became unusable. Taking down the presence server seemed to alleviate the troubles. Also, we have an intermittent issue with phone reboots and lost calls, particularly on extensions that are on more than 12 phones (MAX_BRANCHES is currently set to 12). So, my question is, is this failure (max nr of branches exceeded) an innocuous one? or could it lead to futher failures (and maybe sip message recents... thus the bombardment)... Are there known side affects of this failure? Any info would be appreciated. Thanks Much! Best, Dan Mechanic
