new features: write access to branch attributes
by Daniel-Constantin Mierla 22 Apr '10

22 Apr '10

Hello, yesterday I committed to git new feature that allow write access to branch attributes. It is about branches kept in core before TM takes over and creates the branches for transaction. These branches are filled when you do location lookup, alias db lookup or append_branch in route block. You can update the attributes: - r-uri - outbound proxy address (dst uri) - path - q value - local socket to be used for sending - branch flags More at: http://sip-router.org/wiki/cookbooks/pseudo-… [View More]

Catching internally generated BYE event & other
by Alex Balashov 21 Apr '10

21 Apr '10

Hello, I am using the dialog module to time out excessively long calls: modparam("dialog", "default_timeout", 21600) # 6 hours modparam("dialog", "dlg_flag", 2) ... route { ... ... setflag(2); $dlg_ctx(timeout_bye) = 2; ... ... if(!t_relay()) sl_reply_error(); } I have two unrelated questions: 1) Why does $dlg_ctx(timeout_bye) work here? My understanding is that $dlg_ctx(...) is a PV namespace container that … [View More]

Appended headers are not added in serial forking
by Iñaki Baz Castillo 21 Apr '10

21 Apr '10

Hi, I receive a request, append some custom headers and use "load_gws()" (from LCR module). If the first gateway fails I do "next_gw()" and this second request to the second gateway doesn't contain the previously appended custom headers. Is it the expected behavior? -- Iñaki Baz Castillo <ibc(a)aliax.net>

SQLOps question
by Maciej Bylica 21 Apr '10

21 Apr '10

Hello, I am trying to use SQLOps Module in my kamailio 1.5 configuration. According to your explanations every result of sql_query should be freed just after using that data. So it means that there will be better to fetch for THE SAME data three times instead of just one. Am I right? But nevertheless I've been trying to query just one and free the result of the sql_query at the end of the file. Could sb tell me if the result of sql query executed in the main part of the script is remembered … [View More]

PVs in Regular Expression Transformations
by jh＠tutpro.com 20 Apr '10

20 Apr '10

i tried to embed a PV in regex transformation, but didn't get desired result. is it possible or must regex only contain strings. here is an example, where the idea is to strip string "456" from the end of string "123456": $var(test) = "123456"; $var(rest) = "456"; $var(test) = $(var(test){re.subst,/^(.*)$var(rest)$/\1/}); xlog("result is $var(test)\n"); unfortunately, the result is 0 rather than "123". i also tried $var(test) = $(var(test){re.subst,/^(.*)\$var(rest)$/\1/}); and $var(… [View More]

[Kamailio-Users] new module: embedded lua
by Daniel-Constantin Mierla 20 Apr '10

20 Apr '10

Hello, few weeks ago I uploaded a new module named app_lua, providing functionality to execute Lua (http://www.lua.org) scripts in your configuration file. Lua is small and fast, therefore fits very well in a sip proxy environment. It has a lot of extensions, so when you cannot do something with existing cfg functions, check this one as well. The readme and the api are available at: http://sip-router.org/wiki/api/lua/devel http://sip-router.org/docbook/sip-router/branch/master/modules/… [View More]
