Feature request: sql row number, route-specific avps

by Jasmin Schnatterbeck

Hi list, while thinking about the idea to build a recursive code block in kamailio.cfg I noticed, that there are no route-specific avps available. Of course you can convert a recursion to an iteration, but you need something like a stack to save variables on it, which is not available also. Do you think it's reasonable to make route specific avps available in future releases? I also noticed, that it does not seem to be possible to get the number of result rows of avp_db_query - may (in the case of an successful query) can the function return the number of results for example? Thank you very much... Jasmin

mi dp_translate fails

by jh＠tutpro.com

while trying to figure out, why 'mi dp_reload' does not work, i also noticed that 'mi dp_translate' fails too (for another reason) if input starts with 0. for example, mi dp_translate 1001 03456 does not match to match_exp ^03. the reason is that mi operation strips 0 from 03456 giving to dp translate function this: Apr 3 10:56:21 localhost /usr/sbin/sip-proxy[31822]: INFO: dialplan [dp_repl.c:292]: input 3456 if i try with string mi dp_translate 1001 "03456" translate fails too, because now also quotes are included in the input: Apr 3 10:57:11 localhost /usr/sbin/sip-proxy[31822]: INFO: dialplan [dialplan.c:540]: input is "03456" any suggestions on how to fix this? -- juha

kamctl and sercmd unification proposal

by marius zbihlei

Hello, As kamailio and ser get more and more unified, sharing common modules and core, one of the last remaining points is the intermixed usage of kamctl and sercmd to setup specific parameters. One example is the cfg framework changes (from ser) that Kamailio 3.1.0 will bring, that will require the use of "sercmd" on setting specific module config params. The issue is that the documentation also references the "kamctl" utility to specify reload actions etc. What I suggest is that we strip kamctl with its fifo capabilities and leave it only with DB, ACL management and such(that sercmd doesn't provide), and use only sercmd on examples in the documentation files. This will require no changes to code (well some features from kamctl will be deprecated), but only documentation changes. This will ensure that documentation is kept well organized and coherent across modules. These are the modules required to use sercmd (based on functionality), the 4th case being the one that I am mostly interested (offers full access to Kamailio commands) 1. basic (required for every case - basic ser commands) : modules/ctl/ctl.so 2. configuration framework change : modules/cfg_rpc/cfg_rpc.so 3. fifo comands (kamctl fifo) : modules/mi_rpc/mi_rpc.so (does not require modules_k/mi_fifo/mi_fifo.so) In this case no kamailio core commands are available (like kamctl debug, kamctl uptime, kamctl which) Because readline is based on the which command (lists all available commands), no tab completion is available 4. all K commands : along with mi_rpc, module_k/kex/kex.so is required. In this case sercmd has tab completion (because core commands like which are available) Of course the removal of kamctl fifo commands will mean that module_k/mi_fifo/mi_fifo.so module will not be required anymore(But I strongly suggest that we keep it to allow backwards compatibility) Suggestions?! Cheers Marius
