HANGUP_CAUSE after bridge in outbound ESL
by Dmitry Sytchev 02 Mar '11

02 Mar '11

Hi All What is correct method to get bridge status after execute("bridge") in ESL? I have inbound call that gets bridged to SIP endpoint. I need to know whether it was ORIGINATOR_CANCEL or BUSY or something else, but if I use sync, seems I can't determine ORIGINATOR_CANCEL status, because it is set on a-leg which is destroyed first after hangup. Is there a way to get bridge status without messing with events and event source filtering by channel uuid or event type? -- Best regards, Dmitry Sytchev, IT Engineer

Does FS handle three-way calling on the same POTS?
by GillesToo 01 Mar '11

01 Mar '11

Hello My ISP offers basic PBX features and free calls through when plugging a phone in an RJ11 on the ADSL modem. I'd like to hook up a PC to the modem with an FXO module, and use three-way calling so that the server calls me back on my cellphone, and then lets me call a number through the server before switching to a conference call. Poor man's callback system :-) I finally got Asterisk to make the first call, and put it on hold, but it stops there: It appears that Asterisk is unable to create a second channel on the same FXO module when a call has been put on hold ("app_dial.c:1310 dial_exec_full:Unable to create channel of type 'Dahdi' (cause 0 - Unknown)"). I was wondering if someone had successfully used Freeswitch in this scenario? FWIW, here's my extensions.conf: ============== [from_fxo] exten => s,1,Wait(2) exten => s,n,Set(GLOBAL(CID)=${CALLERID(num)}) exten => s,n,Hangup() ;script waits and creates callfile exten => h,1,system(/var/tmp/test10.lua ${CID}&) ;context used by callfile [callback] exten => start,1,NoOp(In callback, CID is ${CID}) ;how to wait until remote phone picked up? exten => start,n,Wait(5) exten => start,n,Answer() exten => start,n,Playback(tt-monkeysintro) exten => start,n,Flash() ;BAD exten => start,n,Dial(Dahdi/1/${GSM}) ;does ring second number, but no actual voice channel exten => start,n,SendDTMF(456789) ============== Thank you. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Does-FS-handle-three-way-call… Sent from the freeswitch-users mailing list archive at Nabble.com.

Thoughts about mod_conference enter-sound, when wait-moderator has been set
by Peter Olsson 01 Mar '11

01 Mar '11

Good afternoon (at least for me)! Stupid question maybe - but here it goes :) When I configure a conference to wait for the moderator before connecting people, I've noticed that "enter-sound" is played synchronously. Is there any special reason for this? I'm thinking about adding a new parameter to allow it to play asynchronously, even when in this mode. My reasons for this is if there are 50 people logged in, and the moderator connects to the conference, there will be lots of time spent just to play the enter-sound for each member. 1 second of sound for each member will cause 50 seconds before it has played them all. It makes sense in the case when the caller's name is read, but for a common enter-sound I think an asynchronous playback would be good enough? /Peter

Compilation with -march options
by curriegrad2004 01 Mar '11

01 Mar '11

Is compiling FreeSwitch with the -march option in gcc a good idea? Because I just compiled the latest git using the -march option targeted for a Pentium 3 Processor and it did seem to increase the performance slightly in switching calls and transcoding calls. So far I haven't seen any adverse effects of doing this, but I was wondering if anybody else out there is also compiling FS with a march option and saw some performance increase or adverse effects...

T.38 Issues with passthrough handshaking
by Johannes Jakob 01 Mar '11

01 Mar '11

Hi, I'm having some serious trouble getting outbound t38 passthru to work in the following scenario: SIP Upstream <> FreeSWITCH <> Asterisk <> SIP ATA <> analog fax I'm not sure if it's a plain FS problem, but I have to start somewhere and I found at least one problem (I think) with FS's behaviour when negotiating with the gateway. Inbound T.38 faxes, when the ATA has to do the reinvite, work perfectly fine from one end to the other. Outbound faxes on the other hand, don't work at all. Here are the important config parts: dialplan before bridging to gateway: <action application="export" data="t38_passthru=true"/> <action application="set" data="proxy_media=true"/> <action application="set" data="bypass_media=false"/> directory-entry for the asterisk-registration: <param name="t38-passthru" value="true"/> and <variable name="proxy_media" value="true"/> <variable name="bypass_media" value="false"/> and finally the gateway's sip_profile: <param name="t38-passthru" value="true"/> <param name="inbound-proxy-media" value="true"/> So much for introduction... When trying to send a fax to 017286483798, this is what happens on the SBC: asterisk "client" is sending the plain audio INVITE to SBC:

Is there any good pcap anonymizing utitlity, that can substitute application layer stuff as well? Well, *any* help/hint would be appreciated very much ;) Thanks in advance, John

problem with voice quality
by joy this 01 Mar '11

01 Mar '11

Dear all: The scenario is that, when I use 3CX (PCMA) to call XLite, 3CX will hear loud noise but XLite is fine. And I found that it would only happen when XLite supports PCMA and PCMU simultaneously. If XLite only support PCMA, everything is fine. Maybe it is because of the old version of Freeswitch, I download the latest version yesterday and re-test. The result is that 3CX hear nothing instead of noise. I use Wireshark to survey packages, and the server does not transfer UDP packages to 3CX. I check the log file, it is as below. -----3CX hears nothing----- 2011-02-24 20:17:30.724125 [DEBUG] sofia.c:4683 Channel sofia/internal/1000@thisjoy.x.x:5060 entering state [completed][200] 2011-02-24 20:17:30.724125 [DEBUG] switch_core_session.c:709 Send signal sofia/internal/1000@thisjoy.x.x:5060 [BREAK] 2011-02-24 20:17:30.724125 [DEBUG] switch_channel.c:2790 (sofia/internal/1000@thisjoy.x.x:5060) Callstate Change EARLY -> ACTIVE 2011-02-24 20:17:30.724125 [NOTICE] switch_ivr_originate.c:3363 Channel [sofia/internal/1000@thisjoy.x.x:5060] has been answered 2011-02-24 20:17:30.724125 [DEBUG] switch_ivr_originate.c:3408 Originate Resulted in Success: [sofia/internal/sip:1001@114.24.x.x:56922] 2011-02-24 20:17:30.739750 [DEBUG] switch_ivr_originate.c:3408 Originate Resulted in Success: [sofia/internal/sip:1001@114.24.x.x:56922] 2011-02-24 20:17:30.739750 [DEBUG] switch_core_session.c:709 Send signal sofia/internal/sip:1001@114.24.x.x:56922 [BREAK] 2011-02-24 20:17:30.739750 [DEBUG] switch_core_session.c:709 Send signal sofia/internal/1000@thisjoy.x.x:5060 [BREAK] 2011-02-24 20:17:30.739750 [DEBUG] switch_ivr_bridge.c:1234 (sofia/internal/sip:1001@114.24.x.x:56922) State Change CS_CONSUME_MEDIA -> CS_EXCHANGE_MEDIA 2011-02-24 20:17:30.739750 [DEBUG] switch_core_session.c:1116 Send signal sofia/internal/sip:1001@114.24.x.x:56922 [BREAK] 2011-02-24 20:17:30.739750 [DEBUG] switch_core_state_machine.c:320 (sofia/internal/sip:1001@114.24.x.x:56922) Running State Change CS_EXCHANGE_MEDIA 2011-02-24 20:17:30.739750 [DEBUG] switch_core_state_machine.c:369 (sofia/internal/sip:1001@114.24.x.x:56922) State EXCHANGE_MEDIA 2011-02-24 20:17:30.739750 [DEBUG] mod_sofia.c:552 SOFIA EXCHANGE_MEDIA 2011-02-24 20:17:30.974125 [DEBUG] switch_rtp.c:2985 Correct ip/port confirmed. 2011-02-24 20:17:30.974125 [DEBUG] sofia.c:4683 Channel sofia/internal/1000@thisjoy.x.x:5060 entering state [ready][200] 2011-02-24 20:17:31.021000 [DEBUG] switch_core_session.c:771 Send signal sofia/internal/sip:1001@114.24.x.x:56922 [BREAK] 2011-02-24 20:17:31.021000 [DEBUG] switch_core_session.c:771 Send signal sofia/internal/1000@thisjoy.x.x:5060 [BREAK] -----log end----- When XLite only supports PCMA, it would be an additional log: 2011-02-24 20:16:06.661625 [INFO] switch_rtp.c:2968 Auto Changing port from 192.168.1.1:51508 to 114.24.x.x:51508 And I test it again by using a public VoIP server ( sip.lowratevoip.com) there is no noise or silence situation, everything is fine. Does XLite get bugs? Why the public server can deal with the situation? Could anyone help me? Sincerely yours, thisjoy.

conference dialing and montly billing
by deniro 01 Mar '11

01 Mar '11

Hi All I would like to write some type of billing program that will collect the charges for each account monthly When someone calls into the (freeswitch) conference by dialing toll free number or local number and enters PIN number the program will recognize that and start collecting number of minutes and number of persons dialed in and calculate the amount of dollars. Lets say conference is 10cent/per minute /per person for a tool free number Each time people dial into conference it will calculate total amount by person and by minutes, and generate monthly billing. The PIN numbers may be different for conferences that belong to same account. How would I do such thing? Where do I start from? Is there any sample programs like it somewhere out there Which language would be best to it with I would pay for any professional services Thanks in advance deniro--

[ANNOUNCEMENT] EVERYONE PLEASE READ
by Anthony Minessale 01 Mar '11

01 Mar '11

Hi, I just want to give a reminder that we have a growing community and we want to put our resources to their best use. Here are some important things to consider. Many of you are already doing these things so if you already are, thank you, please help encourage others to follow your example. 1) We have a bug/issue tracker site using JIRA: http://jira.freeswitch.org This site is for reporting and discussing issues. Please use this tool to keep track of issues you have. Even if it's not a bug we can easily close it tagged "not a bug". Also please help out when you can by reviewing this site to see if you can provide answers to other people. 2) If you see someone complain about the WIKI please remind them that anyone can edit the WIKI and if it's wrong we can clean it up. It takes longer to complain about the wiki than it does to edit it to be correct or add the missing info. That is the idea behind wikis. 3) Please take the time to provide answers to any questions you may know when perusing the list. The more people who help the less work it is to keep everyone informed. 4) Take the time to test the latest development build. Its better to find bugs before we release than after. People tend to anchor themselves to the "official" releases and never try the BETA versions. The sad truth is the tagged release will begin to build a large list of known bugs starting 30 seconds after its tagged. You don't have to run HEAD in production every morning but you should stay up to speed with what's going on with the software and help to produce a stable release that truly is stable. 5) We will be branching 1.0 so it will slow down and taper off from upstream patches from HEAD. Anyone who wants to help maintain that via JIRA and GIT should let us know. Once we branch, most of our attention will still be focused on HEAD and only critical patches or bug fixes will be shared between 1.0 and 1.2 and we will rely on those interested in slower paced development to help keep that code base in order. -- Anthony Minessale II FreeSWITCH http://www.freeswitch.org/ ClueCon http://www.cluecon.com/ Twitter: http://twitter.com/FreeSWITCH_wire AIM: anthm MSN:anthony_minessale@hotmail.com GTALK/JABBER/PAYPAL:anthony.minessale@gmail.com IRC: irc.freenode.net #freeswitch FreeSWITCH Developer Conference sip:888@conference.freeswitch.org googletalk:conf+888@conference.freeswitch.org pstn:+19193869900

Global configuration to enable SRTP in the entire FS system
by Goutham BG 01 Mar '11

01 Mar '11

Hi All, We can enable SRTP for a particular channel/call by setting the variable sip_secure_media in the XML dialplan or in the dial string. Is there any global configuration to enable and enforce SRTP which would apply to all the extensions in the dialplan and all the channels that are created. Thanks Goutham B G
