[Kamailio-Users] debate: module interface

by Daniel-Constantin Mierla

Hello, the new sip router core and librarization of kamailio management (MI) and statistics interfaces affected the module interface. At this time, although all the fields are still in the module interface, some are passive: - mi commands exports - statistics exports - extra processes The modules in the public GIT repository use the either mod_init or mod_register to export them, so everything should work as expected. fyi: if you didn't know so far - mod_register is a function automatically called when a module is loaded, giving the possibility to export components from module in very early stage, e.g., transfomations must be exported via mod_register since they are lookep up while parsing the routing blocks -- mod_register is available in kamailio since 1.5, back ported from sip router core, you just need to implement it in the module, it is not part of module interface. Back to module interface, the three fields mislead private module implementations as everything compiles ok, but at startup the fields are not actually exported. I propose to remove them and document the transition process to new interface, which is practically couple of code lines. It this way people migrating private stuff will notice the change and update. Since we are here and we have to go through each K module and remove the fields from the module interface, maybe we can create a single interface for k and s modules. Doing a short analysis and considering the above three fields removed from k interface, then: - K interface has extra - dlopen flags - needed to specify how the .so is open, required so far by perl module, iirc - PV exports - the list of pseudo-variables exported by module - the cmd (function) exports structure has a field to specify a free fixup function (not implemented for all exported commands). The goal is to allow calling functions exported by modules for higher application languages, like perl so far, where it is needed to free the memory allocated by fixup function - S interface has extra - rpc exports - exported rpc commands - onbreak function - is this used?!? couldn't find docs about or a use case, so I consider it obsolete Then common interface would be: - name - dlopen flags - mod parameters - mod commands with free fixup - rpc commands - PV exports - mod init - child init - mod destroy - onreply callback Probably we can normalize it a bit more, comments and suggestions are welcome!

[Serusers] 400 bad request of SUBSCRIBE

by 静于

hi I use pa module to support SUBSCRIBE request which Event header is "presence", and the function I used in ser.cfg is as follow : if (method=="SUBSCRIBE") { if (!t_newtran()) { log(1, "newtran error\n"); sl_reply_error(); }; handle_subscription("registrar"); break; }; But the response of this request is 400 error while parsing header Server: SIP Express Route (0.9.6(i386/linux)) I find there is no place in source code to parse Server header I am I miss something in ser.cfg or any other modules should be loaded ? Could any one tell me why? ___________________________________________________________ 好玩贺卡等你发，邮箱贺卡全新上线！ http://card.mail.cn.yahoo.com/

[Kamailio-Users] Fwd: Re: RES: Can someone help me?

by Raúl Alexis Betancor Santana

Sorry Rafael, the .cfg is not big ... moreover it's a simple .cfg compared with other ones I worked on. Also I will not review/debug your config for you. Just try to do a flow analisys and check where you are wrong. With a fast read .. I could tell you that you are having troubles with the failure routes at least .. -- Raúl Alexis Betancor Santana Dimensión Virtual

[Kamailio-Users] How to get the destination IP

by catalina oancea

Hello Is there a way to find the IP address that the request will be sent to using kamailio.cfg ? For example if extension is behind NAT, after lookup() I have in $rd the IP in the contact column of location table, not the actual IP in the received column. I couldn't find a pseudovar for this. Thanks, Catalina
