Monitoring Dispatcher
by Tim Bowyer 08 Jun '18

08 Jun '18

Hi All, Currently trying to work out the best way to keep track of how many calls are being sent to any given dispatcher destination. I remember being able to do this years ago with the load balancer module in OpenSIPS: opensipsctl fifo lb_list. Dispatching algorithm '10' seems to be the best fit for my requirements, as I'm essentially wanting to send calls to a large quantity of FreeSwitch docker containers acting as fax receiving nodes. Equal weight, just filling them in some balanced fashion. Any hints or ideas would be much appreciated! Kind regards, Tim Bowyer

RFC: dispatcher refactoring to use xavp and options for attributes
by Daniel-Constantin Mierla 06 Jun '18

06 Jun '18

Hello, I am starting a discussion here about my plans to do a bit of refactoring to dispatcher module and gather some feedback if people think of other improvements. 1) First is about moving from using avps to xavps. It should simplify at least the config in terms of modparams, but also makes it more coherent in storing the details of destination record for serial forking. Practically, from a bunch of avp parameters, there will be one to set the root xavp name, and the old "avps" will be fields inside the xavp. 2) The second is about the attributes field. I am considering to add the option to load additional attributes from dedicated columns when using database. So besides the attrs column, one can specify via a mod param additional columns to be loaded and added to attributes, like: modparam("dispatcher", "xattrs", "weight,socket,maxload") The attributes string will be the value of "attrs" column concatenated with "weight=val1;socket=val2;maxload=val3" (the valX being the corresponding values in those columns). This should make easier the management of the database records. For the option with a text file, no changes will be done. 3) Anything else that one thinks would be good to add to dispatcher? Cheers, Daniel PS. I wrote to both sr-dev and sr-users, to get the attention of the two communities. However, you can reply only to sr-users (larger community) if you are not on sr-dev, because this discussion is about features of the module, not technical aspects of coding. -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference -- www.kamailioworld.com

Re: [SR-Users] Install IMS Modules over KAMAILIO 5.1
by John M 06 Jun '18

06 Jun '18

First compile Kamailio 5.1 binaries and start the services with Kamailio 4.x IMS configuration files. You need to remove few of the deprecated modules. Then compare the working configuration with 5.X IMS cfg files. You can use OpenIMS HSS application. Configuration is straight forward. Calls can be tested using Boghe IMS client. Regards, Uts Hello, not much into IMS myself, and I see you somehow sorted out the Kamailio part, but in case it helps, you can find sample configuration files in the source code tree at misc/examples/ims/ As for FHOSS, I am not sure if that project is active/maintained. Maybe other guys here using IMS extensions can comment more.

Any idea in this regards? I understood it's structure of HI2Operations as ASN.1 IRI-HI2, I attached it. I think i should convert SIP signalling flow to this structure for transmission. Is it right way that i am doing?

TOPOS module errors
by Enrico Bandiera 06 Jun '18

06 Jun '18

Hi, I'm trying to use the TOPOS module to solve some MTU issues we have (we have multiple kamailio servers in our architecture and route/via headers are becoming a problem) The module seems to work but I'm getting these errors on the log: 0(94) ERROR: topos [tps_storage.c:480]: tps_db_insert_dialog(): No database handle - misconfiguration? 0(94) ERROR: topos [tps_storage.c:412]: tps_storage_record(): failed to store I get these errors for some time after running kamailio and then they stop appearing. Data is inserted on topos_d and topos_t on the db, so I'm not sure what the error is referring to. Any idea? Thanks, Enrico.

What could I do to get rid of them? Thanks, Minh
