Hi All I managed to figure out that the table had not been created in the database. So i deleted the install.lock file in the Siremis directory to run the install again. This time I clicked on all the boxes that were on step 2: Create Siremis Database - this create database 'siremis' Import Default Data - this imports initial data into database 'siremis' Update SIP Database - this updates the structure of Kamailio database for accounting and charts modules Replace DB Config - this updates Siremis configuration file with the details to access databases Then after it had finished I was able to login using the default admin/admin. Thanks for the reply Max greatly appreciated for the time taken to do so - Ivan - I didnt get chance to test what you had put however I will take a note of it for future reference.......hopefully I may be able to return the favor in the future if you guys need a hand.

UAC module
by Ron Hopson 20 Aug '12

20 Aug '12

Hello, I cannot create a configuration consistent with uac_reg_lookup. Does someone have a configuration with a simple example of uac_reg_lookup that works with db_text file uacreg? I have kamailio 3.3 running on linux. Based on suggestions in http://kamailio.org/docs/modules/3.3.x/modules_k/uac.html and http://by-miconda.blogspot.com/2010/10/best-of-new-in-kamailio-310-10.html I created this record in db_text file uacreg: 2:12345678:daniel:mysipserver.com:daniel123:sipprovider.com:sipprovider.com:daniel123:xxxxx:"sip:sipprovider.com" I assume that function uac_reg_lookup retrieves registration information from this record after it is loaded into a memory table. One version of the configuration file is attached. Here are three examples of failures to create a configuration. $rU = 12345678; if(uac_reg_lookup("$rU", "$ru")){ #line 73 0(13856) DEBUG: <core> [rvalue.c:2857]: RV fixing type 1 0(13856) DEBUG: <core> [rvalue.c:2861]: RV is int: 12345678 0(13856) DEBUG: <core> [rvalue.c:2857]: RV fixing type 4 0(13856) DEBUG: <core> [route.c:929]: fixing uac_reg_lookup() 0(13856) ERROR: <core> [route.c:1216]: fixing failed (code=-1) at cfg:/usr/local/etc/kamailio/kamailio.cfg:73 --------- $rU = "12345678"; if(uac_reg_lookup("$rU", "$ru")){ #line 73 0(13973) DEBUG: <core> [rvalue.c:2857]: RV fixing type 2 0(13973) DEBUG: <core> [rvalue.c:2865]: RV is str: "12345678" 0(13973) DEBUG: <core> [rvalue.c:2857]: RV fixing type 4 0(13973) DEBUG: <core> [route.c:929]: fixing uac_reg_lookup() 0(13973) ERROR: <core> [route.c:1216]: fixing failed (code=-1) at cfg:/usr/local/etc/kamailio/kamailio.cfg:73 -------- $rU = "12345678"; $ru = "sip:mysipserver.com"; if(uac_reg_lookup("$rU", "$ru")){ #line 74 0(13976) DEBUG: <core> [rvalue.c:2857]: RV fixing type 2 0(13976) DEBUG: <core> [rvalue.c:2865]: RV is str: "12345678" 0(13976) DEBUG: <core> [rvalue.c:2857]: RV fixing type 2 0(13976) DEBUG: <core> [rvalue.c:2865]: RV is str: "sip:mysipserver.com" 0(13976) DEBUG: <core> [rvalue.c:2857]: RV fixing type 4 0(13976) DEBUG: <core> [route.c:929]: fixing uac_reg_lookup() 0(13976) ERROR: <core> [route.c:1216]: fixing failed (code=-1) at cfg:/usr/local/etc/kamailio/kamailio.cfg:74 --------------------- regards, Ron Hopson

Re: [SR-Users] [sr-dev] new feature: option to remove, contacts based on sip nat keepalives
by Yufei Tao 20 Aug '12

20 Aug '12

That's a very useful feature for updating presence information on behalf of some clients that do not support presence, or simply crashed. I will be watching this space for TCP/TLS support :) Is there any other existing way to achieve this for clients over TCP/TLS?

Siremis login issue

20 Aug '12

Hi All I have installed Kamailio with Siremis, Kamailio is working fine and starts and I have been through the initial setup for Siremis however when i go to login to the web management page it gives an error: "Error in query:: SELECT T0.id, T0.username, T0.password, T0.enctype, T0.email, T0.status, T0.lastlogin, T0.lastlogout, T0.create_by, T0.create_time, T0.update_by, T0.update_time FROM `user` T0 WHERE T0.username='openser' and status='1' LIMIT 1. SQLSTATE[42S02]: Base table or view not found: 1146 Table 'siremis.user' doesn't exist" I have tried the default "admin/admin" login as mentioned in the install guide and have also tried the default passwords for Kamailio "openser - (with default password 'openserrw') and openserro - (with default password 'openserro'). I have also tried root/*password* and also siremis/siremis which is contained in the /var/www/siremis-3.2.1/siremis/config.xml however none were successful and the same error appeared.

new feature: option to remove contacts based on sip nat keepalives
by Daniel-Constantin Mierla 20 Aug '12

20 Aug '12

Hello, over the weekend I committed the code that allows to remove contacts from location table if the device does not respond to several attempts of SIP nat keepalives (usually OPTIONS requests). The feature works only for SIP over UDP, being the only transport for which nathelper module sends keepalives (or sip ping requests as written in some docs). Also, the lack of keepalive reply is tracked only for location records stored in memory (so it does not work with db only mode for usrloc). This is because the keepalives are sent stateless, not using tm module, to avoid overloading of timers and shared memory when dealing with large subscriber base -- therefore the implementation is very lightweight in using resources, targeting of course scalability. Detection of replies for keepalives is done based on from tag which carries the internal unique id of the location contact (which is available from v3.3). In order to enable this feature you have to set the keepalive_timeout parameter of nathelper module -- that's the only addition you have to add to a config that sends SIP nat keepalives. Internally, the modules store the timestamp of the last SIP keepalive reply (nathelper detects the right reply and calls usrloc API for storing the timestamp in contact structure in memory). http://kamailio.org/docs/modules/devel/modules_k/nathelper.html#id2535244 Before sending a new keepalive to a contact, it is checking if the last keepalive reply is older than keepalive_timeout value and if yes, will lower the expires to 10 seconds (if the expires is higher). There is no special handling of keepalive reply codes, all of them will update the last keepalive timestamp. This feature should be useful in mobile networks, to avoid stacking lot of invalid contacts which could result in lot of branches causing many retransmissions. There is plant to go for tcp/tls as well and detect when the connection is down, but looks like no spare time in the near future. However, right now using set_forward_no_connect() will avoid trying to create new connections for natted uses whose registration connection is down. Testing and feedback will be welcome.

OK, I understan the AVP's are per transaction. How can I save info from the invite and use it on the bye? $sht(...)? $dlg(flag), $dlg(set) ?

Request for advice, running SIP-Router in OpenVZ Container
by JR Richardson 19 Aug '12

19 Aug '12

Hi All, I'm considering running Kamailio as a virtual machine, with such low utilization, it doesn't seem to make sense to keep running it on a physical host server. I've been virtualizing Asterisk PBX's for years and run a host of other virtualized servers with OpenVZ, VMware and MS V-Server without issues. I'd like any opinions or thoughts about pitfalls or caveats I should be aware of specific to virtualized SIP-Router/Kamailio. Thanks in advanced. JR

append_branch with pseudo variables
by Carlos Ruiz Díaz 17 Aug '12

17 Aug '12

Hello guys, Why I can only append_branch() a SIP URI as a literal constant string? Why not from a pseudovariable? It's the same for most of the core functions. My intention is to do something like this: append_branch("$cnx3a(route1)"); t_relay(); where cnx3a is a variable containing the SIP URIs. The only "fix" I have found for this is by doing it as follows: $ru = $cnx3a(route1); append_branch(); t_relay(); Is there any other (and more elegant) way? Regards. Carlos.
