Guys, We've developed a module called lcr_rate.so, which acts on top of the existing lcr.so module and performs real cost-based least cost routing. It's quite Sipwise specific, so I wanted to ask whether there is any interest in - or it makes sense to - pushing it to upstream. The module is really simple from its functionality point of view. You call load_gws() as usual from the existing lcr.so module, and the lcr_rate.so module takes the resulting AVP and reorders the entries based on the cost per gateway: loadmodule "lcr.so" modparam("lcr", "gw_uri_avp", "$avp(s:lcr_uri_list)") loadmodule "lcr_rate.so" modparam("lcr_rate", "gw_uri_avp", "$avp(s:lcr_uri_list)") load_gws(...); lcr_rate("$rU", "$rd"); while(...) { next_gw(); ... } The actual cost per destination is calculated using libswrate, which we will publish as GPL along with the module. However, the whole inner workings are specific to our sip:provider CE/PRO platforms though, which means we are using the lcr_gw.flags column to store the gateway id from another table, which maps to gateway groups, which in turn reference to a billing profile id where the actual fees per destination are attached to. So to get any practical use out of this, you'd need to use the Sipwise provisioning and billing databases, or adapt your backend to reflect that. A way out of this lock-in would be to use diameter or radius to get the actual cost for a call, as this might be a standardized interface to do so (IMS?), but we currently don't use that. However, the module could later be modified to take advantage of that, once a diameter client is available in the main branch. If you say it doesn't make any sense at all (which might be likely), we're going to provide the source on our github page for people interested in it. Any comments/opinions? Andreas

default flavour set to kamailio

by Daniel-Constantin Mierla

Hello, based on community interaction, development, package distributions and documentation maintenance in the recent years, the default flavour has been switched now to 'kamailio'. As written in my previous email, we started the last phase to complete the integration between kamailio-ser, aiming to get to a unique database schema and set of modules in maximum 6 months. Kamailio is the most spread and popular flavour, presented in many linux/unix distributions, being the one released and packaged periodically. So it will stay as main flavour, the one officially released by the project. Those that want can take the sources and build their own flavour, as the support in Makefile system is kept. Once the integration is finished, the flavour system will just set the application name, nothing else. From the open source project perspective, the resources will be allocated only on releasing under the main/default flavour (Kamailio).

Last phase of integration for kamailio - ser

by Daniel-Constantin Mierla

Hello, we plan to start the last phase of integration between kamailio and ser. After about 4 years with same source code tree, there is still some overhead caused by several duplicated modules. Following the decision to go on with the most developed components and absorb the missing features from the duplicates, kamailio modules are those that will stay (move to modules/ eventually) and get updates when needed. We used same decision to keep the core and makefile system from ser, adding to it what was extra in kamailio. I present next a summary of what is planned to happen: 1) Modules from modules_s/ that will be simply moved to modules/ because there is no conflict at all: - avp, avp_db, db_ops, eval, mangler, print, print_lib 2) Modules from modules_s/ that will be renamed and moved modules/ because it is mainly only conflict of name, but not in the backend (e.g., database): - auth_db => auth_dbattrs - because it uses (attribute,value) style to store subscriber profiles, which can be a preferred alternative for many out there - ldap => db2_ldap - it is a DB APIv2 connector to ldap server - bdb => db2_bdb - it is a DB APIv2 connector to berkeley db (to be double-checked) - xlog => xprintf - it uses %spec to print log messages with all the code inside the module - the only reason not discarding it and stick only to modules_k/xlog for the moment is because it is used from other modules, otherwise modules_k/xlog has more features (e.g., syslog facility, color printing, a.s.o) 3) Modules from modules_s/ that will be removed, after absorbing some extra features: - usrloc/registrar => get the ability to store AVPs per contact (modules_k is more advanced in features, like path/gruu/partial outbound support, publish presence states, etc.) - several modules must be reviewed: acc*, radius*, permissions, pike, gflags, options, timer 4) Modules from modules_s/ that will be removed, by moving to obsolete/ directory - the rest of them from modules_s/, like dialog, xcap, cpl-c, presence_b2b, dispatcher, dbtext, domain, etc. The categories and their content are not nailed down, it is the purpose of this discussion to see if something was overlooked. We hope to end this process in max 6 months time - after that will be a unique database schema and a unique set of modules. Flavour system in the Makefile will stay just for letting people choose easier the name of binary, otherwise everything will be the same (e.g., what is compiled, installed, etc).
