outgoing speech path is broken sometimes in 1.4.14
by Den Pavlovsky 08 Dec '14

08 Dec '14

Hi I installed FS 1.4.14 from git Now I test outgoing calls with Radius authorization. The problem that I encountered is that sometimes there is no RTP from Freeswitch. I see it in tcpdump dump. Iptables -no restrictions. I also tested when there is no mod_rad_auth loaded (I commented it out in autoload_configs/modules.conf.xml). - the same result And when I put the call on hold - then when I return - the call path is normal. Any help on how to debug this issue is appreciated. Does anyone encountered the same behaviour? The version FreeSWITCH Version 1.4.14+git~20141119T221113Z~ca1d990cfc~64bit (git ca1d990 2014-11-19 22:11:13Z 64bit) P.S. I am new to FS. I came from Asterisk world.

Hi Deon, If you are looking for a billing engine (which I find it more suitable than complete billing system for hosted environments, same approach as FreeSWITCH +/or Kazoo - it does not enforce any business rules), take a look on CGRateS. It is opensource, very fast (12k+ requests per second), real-time, scalable (fire up more instances as you need them), feature-rich (multi-tenancy, supports advanced concepts as multiple calls out of same account, multiple balances inside one account, derived charging - eg: reseller chaining, grouped rating - charge using various billing increments within same call), API driven (full set of APIs available in both JSON and GOB) and production ready (runs already at MVNOs, ISPs, wholesale suppliers sites live). Happy to help you more! DanB

Re- LUA audio playback on Windows 64bit not working? (FOUND & FIXED)
by Andrew Keil 08 Dec '14

To all, Found the issue below: Removed the inline="true" from the xml dialplan and everything works as expected. <action inline="true" application="lua" data="ASKTestLua.lua $2"/> Now: <action application="lua" data="ASKTestLua.lua $2"/> Not sure why I put it there in the first place. Sorry about that. Andrew From: Andrew Keil Sent: Monday, 8 December 2014 1:18 PM To: 'freeswitch-users(a)lists.freeswitch.org' Subject: Re- LUA audio playback on Windows 64bit not working? To FreeSWITCH users, I am just starting to use Lua inside FreeSWITCH and I am having difficulty with playing back audio to the caller.

Hi, I'd like to have the country code "+49" removed from destination_number and changed to "0" I tried: <extension name="international" continue="true"> <condition field="destination_number" expression="^\+49(.*)"> <action inline="true" application="set" data="destination_number=0$1"/> </condition> </extension> but after correctly executing this extension-statement it reverts to the original version of destination_number

Recommendation for Billing for Hosted PBX Platform
by Deon Vermeulen 07 Dec '14

07 Dec '14

Hi, I've been looking at the Kazoo as a very viable option as a HostedPBX platform, but don't find any information with regards to Billing. I've also been tracking the thread about recommended GUI where 2600Hz are in the process for updated the code in git for Blue.box. This also looks like a possibility for a HostedPBX platform, but then again I have no idea about the Billing software to use for this. FusionPBX is a top contender if no the number 1 for a HostedPBX platform but again information for Billing is lacking. I would like to know what the feel out there is for Billing on a HostedPBX Platform, i.e. Cloud. If would be great if there is an opensource Billing system. I've purchased the jBilling Telecom guide, but no where can I find information about integrating with FreeSWITCH nor implementing it for a HostedPBX platform in the Cloud. Kind Regards

delay_echo with half of time
by Julio Cesar Esteves Cabezas 05 Dec '14

05 Dec '14

Hi, The delay I am getting from delay_echo is roughly half of what I pass as parameter in its data. This is the snippet, and the log shows on screen that I am passing what I intend to <extension name="delay_echo"> <condition field="destination_number" expression="^\*7(\d)$"> <action application="answer"/> <action application="set" data="delta=${expr(1+1000*$1)}"/> <action application="log" data=" *** delta = ${delta} "/> <action application="delay_echo" data="${delta}"/> </condition> </extension> I am running FreeSWITCH Version 1.5.12b~64bit ( 64bit) (as per command "version" in fs_cli) in a VMware VM with OS=Windows Server 2012. Thanks.
