Scaling FreeSWITCH horizontally with master master replication
by Ashwin Rath 04 Jan '15

04 Jan '15

Hi All I am trying to scale FS by having individual nodes running FS that have the core in Postgres. The idea is to have any number of FS boxes behind a load balancer depending on the load. Just wanted to ask if master master replication is reliable for say 10 FS nodes holding presence as well as session info ? or would it just bea better idea to build a highly available postgres sql cluster and point all FS to it ? -- Ashwin Kumar Rath

Hello guys, That was the problem... stupid me... I had no condition on the 9999 extension... Amazing how staring and staring at the dialplan and not seeing anything can leave you blind.

Unbridge and send to queue
by David Villasmil Govea 03 Jan '15

03 Jan '15

Hello Guys, I receive a call from side A and send it out to side B. I need to unbridge this call once it is answered and send the B side to a queue to give it moh. How do I do that? I'm doing everything with lua and I've tried: on my dialplan I have: <action application="set" data="execute_on_answer=lua /usr/local/freeswitch/scripts/check_answered.lua"/> in check_answered-lua, after checking the call was in fact answered I do: session:execute("transfer", "-bleg 9999 XML default"); and on my dialplan I have: <extension name="9999"> <action application="log" data="INFO SENDING CALL TO QUEUE >>>>>>>>>>>>>>>>>>"/> <action application="lua" data="/usr/local/freeswitch/scripts/queue.lua"/> <action application="hangup" data="NORMAL_CLEARING"/> </extension> queue.lua: session:execute("sched_hangup","+50 alloted_timeout"); session:execute("callcenter","agents_queue"); session:execute("sleep",my_dur); But this doesn't seem to work at all... Can anyone give me a hand? thanks! -- DVG

problem with sequential calling & mod lua session originate
by spros p 03 Jan '15

03 Jan '15

Hello, I am trying to originate a series of calls in sequential order. I am using the pipe notation, for the dial string, however the call never reaches the second destination. When trying a comma or when using the enterprise originate notation (:_:), calls are indeed simultaneously placed. The session is being called as follows in LUA: origination_string = "{ignore_early_media=true,originate_timeout=30,continue_on_fail=true}[origination_caller_id_number=XXXX]sofia/gateway/provider/AAAAAA|[origination_caller_id_number=XXXX]sofia/gateway/provider/BBBBBB" new_session = freeswitch.Session(origination_string, session); Any help would be greatly appreciated. Many Thanks, S

Re: [Freeswitch-users] Canceling sched_hangup and UUID lookup
by DanB 03 Jan '15

Hi Kurtis, Interesting approach you are trying to take. I see however some scalability issues. Unless you are planning to build an office PBX (for which mod_nibblebill should do just fine) and want to go for a more scalable solution, you will be forced to send calls belonging to the same account always to the same node in order to keep the billing for them. Regarding your float64 comments, you are right about trying to avoid them but there it depends on the operations you are doing on the numbers (eg: sum/multiply vs divide). Here is how we solved in CGRateS the issues you are facing: * Each call started will have the global session timeout set on call setup stage (same as you planned it). This is more like security for your call timeout. * We keep an external component responsible for call management and timeout corrections. The timeouts will be recalculated inside external component and if it will be necessary, the sessions will be killed via ESL. This solves another issue you did not cover yet: if you are billing units in advance, you can also refund non-used units at the call end. * On the float issue, we are passing all the calculations through a special object which does the rounding where needed, eliminating the float issues with calculations. So far we could not find a case failing, although we considered initially converting currencies internally to huge-INTs and perform all the operations there (this would force us using always same unit of currency - which we were trying to avoid). Hope it helps! DanB
