Verto: not able to establish media with Firefox 40 with symetric NAT
by Nicolas Trangosi 11 Sep '15

11 Sep '15

Hello, I have installed Freeswitch server 1.6.0 to test Verto. I am able to make call without issues with Chrome or Firefox 39 and browser behind symetric NAT. When I try with Firefox 40 and browser behind symetric NAT, the signaling part is OK, but no media is sent or received. I have took a wireshark trace on server, and it seems that Freeswitch send STUN binding requests always to same destination (and do not try other candidates from SDP or from incoming STUN binding requests). As NAT is symetric, port discovered using ICE are wrong but STUN request sent by browser should allow freeswitch to find right host and port. Thanks for any help, Nicolas

Dialing two destinations simultaneously hangup early
by John Nash 11 Sep '15

11 Sep '15

I need to test a case to generate following user experience .. User dials a number and when call hits freeswitch, freeswitch plays a sound file but the same time dials out to a gateway, that means user hears sound file but at the same time call is being tried by gateway and when gateway sends ring 183 or 180, Sound file stops playing and user hears ringback or any media sent by gateway . I plan to do this by using bridge application to two destinations, One is to play sound file and other to send call to gateway. But how can I hangup the call to extension which is playing Sound file, upon receiving the 180 or 183 from gateway (Second fork )..where should I look for this?

Audio Issue with FreeSWITCH (TLS + SRTP)
by Saurabh Kumar Verma 11 Sep '15

11 Sep '15

Hi, Hope you're doing good. I'm facing an issue with having FreeSWITCH (TLS + SRTP). *Issue:* Audio not coming when I've SRTP(media) enabled on both of the soft-phone endpoints. *Observation: *Audio is coming if we don't use SRTP for media encryption. *Set-up Description:* I'm registered using TLS and able to make call through FreeSWITCH, but call is disconnected after 30 sec because there is not media flow between the endpoints. I have two softphone (we're using Linphone as soft-phone) registered on FS server with extension 1003 & 1010, call flow is like: Call Flow 1003 ------> FS Server -------> 1010 x.x.x.x - Server Public IP y.y.y.y - Server Local IP *NOTE:* *For security reasons replaced the actual IPs.* FreeSWITCH Version Information: *freeswitch@internal> version* *FreeSWITCH Version 1.4.21+git~20150901T202622Z~a223dd0236~64bit (git a223dd0 2015-09-01 20:26:22Z 64bit)* I've done some changes in default dialplan/configuration in FreeSWITCH: 1.

Using Lua to extract TOD conditions from Database‏ -How to do it with multiple entries.
by Jonathan Hunter 11 Sep '15

11 Sep '15

Hi Guys, Wonder if anyone can help. I am testing with time of day routing, and I want to be able to check yearly/monthly conditions before weekly conditions are picked up. I can do this successfully by just inputting XML into the dialplan, and works as expected, my issue is now when extracting the detail required from a database using lua. I for example have 3 entries below for different times of the year; +------------+-------+------+----------------+ | dayofmonth | month | year | dayofmonthtime | +------------+-------+------+----------------+ | 25 | 12 | 0 | 0 | | 1 | 1 | 2016 | 540-1050 | | 10-18 | 9 | 2015 | 600-840 | So when creating directly using xml I get; table.insert(xml, [[<condition mon="12" mday="25" break="on-true">]]); table.insert(xml, [[<action application="set" data="TOD=sales" inline="true"/>]]); table.insert(xml, [[<action application="set" data="Status=closed inline="true"/>]]); table.insert(xml, [[</condition>]]); table.insert(xml, [[<condition year="2016" mon="1" mday="1" break="on-true">]]); table.insert(xml, [[<action application="set" data="TOD=sales" inline="true"/>]]); table.insert(xml, [[<action application="set" data="Status=closed inline="true"/>]]); table.insert(xml, [[</condition>]]); table.insert(xml, [[<condition year="2015" mon="9" mday="10-18" break="on-true">]]); table.insert(xml, [[<action application="set" data="TOD=sales" inline="true"/>]]); table.insert(xml, [[<action application="set" data="Status=closed inline="true"/>]]); table.insert(xml, [[</condition>]]); However my issue is when my lua script extracts them, it loops through the 3 entries (each row) , so that only the 3rd entry is available for on-wards routing as it is populating the dialplan 3 separate times. Can someone let me know what Im doing wrong? The data return is fine and I can implement lua and freeswitch for all other scenarios, its just this one which I am having issue with. Im just doing a query as; local todnew_query = string.format("select * from timeofday_new where todname='sales' and context_name='xx.xx.xx' order by priority") assert (dbh:query(todnew_query,function(todresult) And using the result with some if statements, I wondered if anyone had any advice on this? Thanks Jon

mod_rtmp concurrent calls on same session
by Paul Cuttler 11 Sep '15

11 Sep '15

I was wondering if it's possible to have more than one call running in mod_rtmp without logging in, that is, more than one call running on the one session. I'm getting an error with an invalid chunksize that is terminating the TCP socket. thanks, Paul

fail to add opus to freeswitch
by Assaf Dahary 11 Sep '15

11 Sep '15

Hi, When I installed freeswitch 1.4 long time ago I've commented out #mod_opus because I use SILK only. Now I would like to add the opus codec so I enabled it in the modules.conf and try to compile with: /usr/local/src/freeswitch/make mod_opus-install But it fails with error: Unknown target mod_opus-install make[2]: *** [mod_opus-install-all] Error 1 make[1]: *** [mod_opus-install] Error 2 make: *** [mod_opus-install] Error 2 I also download opus from source and compiled OK but still fail to 'load mod_opus' from cli: switch_loadable_module.c:1391 Error Loading module /usr/local/freeswitch/mod/mod_opus.so How can I add the opus codec? Regards Assaf

uuid_bridge vs intercept
by Ben Hood 10 Sep '15

10 Sep '15

Hi all, I was wondering if anybody can explain the difference between uuid_bridge and intercept. I have an app with parked legs - using the uuid of a parked leg, I can originate a call to multiple endpoints, and the "winner" is piped into the intercept application which effectively bridges the two legs together: originate endpoint1,endpoint2 &intercept(first_uuid) This seems to have the same effect as originate endpoint1,endpoint2 &park() // returns second_uuid And then in another thread uuid_bridge first_uuid second_uuid But I'm not sure whether there's something different going on under the covers. Interface-wise it looks like intercept is an application, and as such, it exposes the necessary calling convention for a successful originate invocation to pipe it's result to, whereas uuid_bridge appears to be a API from mod_commands and hence doesn't suffice the call interface for originate. So on face value, it seems that intercept can join the currently executing channel to a specific uuid, whereas uuid_bridge is executed in a separate context to the two uuids that are being joined together. Because they appear to have same result, albeit invoked in different calling contexts, I was wondering whether there's any fundamental difference between the two methods? Cheers, Ben

fs_cli | show calls | answer timestamp
by Dmitry Mordovin 10 Sep '15

10 Sep '15

Hello All! I use fs_cli api for interraction with FS from my application. Now I wish get current active calls (api show calls) and calculate current duration. "show calls" output many fields, but timestamp represent call originate time and no one field with timestamp represent b_leg answer time (SIP 200 OK message) So, any idea (easy implementation) to obtain SIP 200 OK timestamp or current call duration since 200 OK received?
