Compiling with db_unixodbc
by Grant Bagdasarian 05 Jul '13

05 Jul '13

Hello, I don't know if this has already been reported, but I've downloaded kamailio 4.0.2 and tried to compile it with db_unixodbc. I got the following error: CC (gcc) [M db_unixodbc.so] _con.o _con.c:34:17: fatal error: con.h: No such file or directory compilation terminated. make[1]: *** [_con.o] Error 1 make: *** [modules] Error 1 I looked in: .../kamailio-4.0.0/modules/db_unixodbc and saw there was no con.h file, only a _con.h file. The con.c file was pointing to con.h. So I renamed _con.h to con.h and compiling worked. Regards, Grant

by Sunil Chandrasekharan 05 Jul '13

05 Jul '13

Hi All, I see that Kamailio supports MSRP relay. I wish to configure Kamailio with MSRP. 1. Do i just need to add the MSRP relay module into Include modules and build again? 2. Is there any existing clients, to test SIP and MSRP with Kamailio (e.g file transfer) Please let me know the support links to configure and test MSRP on Kamailio

Load database table in memory
by Grant Bagdasarian 04 Jul '13

04 Jul '13

Hello, I need to query a database for every SIP request coming into Kamailio, but I want this to be handled as fast as possible, so I was thinking of loading the data I need in memory using the HTABLE or MTREE modules. When the SIP request is coming from one of our carriers, the called number ($rU) must be used to get the data for this called number. Normally, I would query the database, using sqlops, and pass the value of $rU as the parameter and get the column values using the $dbr variable. Can this be accomplished with HTABLE or MTREE? Also, the autoexpire parameter in HTABLE; once expired, will the data be reloaded again from the database? Thanks, Grant

Message Waiting
by Daniel W. Graham 02 Jul '13

02 Jul '13

While I have seen other posts I have not found anything that describes my scenario. Kamailio sets in front of a group of asterisk servers which are used in a round robin dispatch group. All asterisk servers share a common database in which voicemail boxes are defined and messages are stored. I'm looking for a way to make message waiting work in this example. I have tried creating a view with basic peer information for asterisk to use for message notification, however asterisk does not 'see' these peers until a call is made to the specific user and the peer info is retrieved from the database, which can delay notifications severely rendering them useless. I also want to avoid sending a copy of the registrations to asterisk servers, as the purpose of the distributed system is to eliminate the large number of sip registrations asterisk needs to manage. I have also seen a couple of script methods that look at the voicemail directory structure for file changes and trigger an application like sipsak to generate the notifications and let kamailio relay them. From what I see, the consensus is not to go this route. In my case the script would need to look at the database level, and maybe some sort of database trigger could be used. What are others doing / what do others recommend as the best way to handle message waiting with a situation where kamailio sets in front of a voicemail server? Any input is appreciated. Dan-

How to cleanup unconfirmed dialog in memory?
by Eduardo Lejarreta 02 Jul '13

02 Jul '13

Good evening Gary. 1.- With regard to session control you can also implement with htable module (avoiding orphan dialog module). INVITE transaction $sht(channels=>$ci) = $avp(s:caller_uuid); BYE/on_failure transaction $sht(channels=>$ci) = NULL; CHANNEL CONTROL ROUTE -> . if ( $shtcv(channels=>$avp(s:caller_uuid)) >= "YOUR TOP") ) { .. Your treatment 2.- My last way is to face dialog module development to achieve your goals, even service restart. The problem is that dialog module is now continuously changing (dialog, dialog_ng, . ) and you'll have to accomplish your development with new changes. Regards. -- Eduardo Lejarreta.
