Re: [SR-Users] kamctl restart and mediaproxy
by Mino Haluz 13 Feb '13

13 Feb '13

You have to figure it somehow with adjusting the python code of media-dispatcher. We have developed special "/etc/init.d/kamailio grace" command, which waits for the moment, when there are no calls, so it can be restarted. It queries mediaproxy every second. In future we will not use mediaproxy anymore - it is not supported in latest version either. rtpproxy gives us better performance results.

hadnling the IP extension calls freeing the PBX channel
by kiran bhosale 13 Feb '13

13 Feb '13

hello , w have PBX gateway along with kamailio. all calls are routed to pbx extensions. but if it happens to be an IP extrension we want the kamailio to handle the speech without keeping the PBX channel busy. if its an analog extension then this channel can be busy but if its IP extension kamailio should handle the speech itself. how is this possible ?? thanks in advance.

pseudovariable values written from app_lua sometimes appear incorrect
by elactrum＠jamailca.com 12 Feb '13

12 Feb '13

Hi, I am using app_lua to frequently store some data in htable and avp entries, using sr.pv.sets. When I read the values using sr.pv.get immediately after writing them, they seem correct. However, when I read them later from Lua, I have noticed that sometimes the value is incorrect or nil. Am I doing something wrong? The following code uses rtimer to duplicate the problem on startup, printing the errors to syslog. Tested on version: kamailio 3.3.1 (i386/linux) 2d0f6f ############### # kamailio.cfg ############### loadmodule "pv.so" loadmodule "xlog.so" loadmodule "htable.so" loadmodule "rtimer.so" loadmodule "app_lua" modparam("htable", "htable", "status=>size=14;autoexpire=0;") modparam("rtimer", "timer", "name=ta;interval=10;mode=1") modparam("rtimer", "exec", "timer=ta;route=LUA_TEST") # the following path may need to change depending on filesystem setup modparam("app_lua", "load", "/etc/kamailio/kamailio.lua") route { route(LUA_TEST); } route[LUA_TEST] { $var(lua_test_key) = $(pp{s.toupper}) + "::"; lua_runstring("htable_test([[status=>$var(lua_test_key)]])"); lua_runstring("avp_test([[status=>$var(lua_test_key)]])"); } ---------------- -- kamailio.lua ---------------- -- Test of sr.pv operations in Lua function htable_test (namekey) local pvar_prefix = "$sht("..namekey pvar_test(pvar_prefix) end function avp_test ( name ) local pvar_prefix = "$avp("..name pvar_test(pvar_prefix) end function pvar_test ( pvar_prefix ) for value = 10000, 10050 do local pvar = pvar_prefix..value..")" --sr.log("info", "Lua attempting to set '"..pvar.."' to value '"..value.."'") sr.pv.sets(pvar, value) end for value = 10000, 10050 do -- now we check what was stored local pvar = pvar_prefix..value..")" local checkvar = sr.pv.get(pvar) if ( tostring(checkvar) ~= tostring(value) ) then sr.err(string.format("CHECK: Lua checking pvar '%s' and got value '%s' which is NOT '%s'", tostring(pvar), tostring(checkvar), tostring(value) )) end end end -- end of kamailio.lua Thanks, -Andrew

DNS error
by Vitaliy Aleksandrov 12 Feb '13

12 Feb '13

Hi, all Have a question about failure_routes. As I remember if kamailio statefuly sent a request and didn't receive a reply script writer can handle this situation at a failure_route[] block. But if kamailio can't resolve a destination from R-URI it sends back 478 reply and finishes current transaction without reaching a failure_route[]. Is it possible to process such a request in a failure_route[] ? Additional details: version: kamailio-3.2.4 t_on_failure() is called before t_relay() I have checked with REGISTER and INVITE transactions.

Yes,Yes I did it the way tm and mediaproxy modules are added... when i check /usr/local/lib/kamailio/modules I found my module and $stat module time is effected.

Handling 302 redirect on group ringing
by Mark Boyce 12 Feb '13

12 Feb '13

Hi All Got a problem handling redirects when more than one phone is ringing. The setup is this; Phone1 - Extension 100 Phone 2 - Extension 101 Phone 3 - Extension 102 & 101 When Phone 1 rings Extension 101 Phones 2 & 3 ring correctly as you would expect. If Phone 2 now sets the on phone forward/redirect we see the following; Phone 1 - Invite sent to 101 Phone 2 & 3 Receive Invites Phone 2 responds with a 302 Redirect Phone 3 Rings. Which again is as you would expect. The problem is that the 302 Message we're getting back is being seen in onreply_route where I cannot add a new branch to handle it. (Error - misused command append_branch / Command cannot be used in the block) If Phone 3 is unavailable / times out / busy / or otherwise does not take the call we then see the 302 from Phone 2 arrive in failure_route where it is handled as expected. The call flow we're trying to achieve is that the redirect is followed whilst the other available phone carries on ringing. I've tried with failure_reply_mode as the default 0 and as 3, both do the same thing. Currently working with kamailio version 3.4.0-dev6 Can anyone spot what I'm doing wrong ? Thanks Mark
