Strange behviour with DTMF
by Kamil Nigmatullin 14 Sep '16

14 Sep '16

I want to implement a little feature, when client in on a queue of mod_callcenter, and is able to press *1 if he want to leave a message. <action application="answer"/> <action application="bind_meta_app" data="1 a s transfer::cvm_3 XML public"/> <action application="callcenter" data="$1"/> Generally it works, but DTMF sometimes (3 of 5) times are not seen (as if it is missng) and pressing *1 together is a success on a third or forurth try. When I use other applications like ivr DTMF works prefectly. Is this a bug? -- Kamil Nigmatullin Tel: 77272323748 mob: 7 (707) 2517003 Skype: kamil.nigmatullin

Variables in a user directory config will not a channel variable
by Alexander Haugg 14 Sep '16

14 Sep '16

Hi, I’m set the valiable „effective_caller_id_numer“ in the user config file. The user is working fine, but the variables are not set to the channel variables. <user id="170"> <params> <param name="password" value="xxx" /> </params> <variables> <variable name="effective_caller_id_number" value="+4989840798170" /> <variable name="any_key" value="any_value" /> </variables> </user> The user 170 is calling another user. In the dialplan, I’m trying this <action application="log" data="ERR effective_caller_id_number=${effective_caller_id_number}"/> The documentation for the user directory says https://freeswitch.org/confluence/display/FREESWITCH/XML+User+Directory#XML… “Any variables defined in the domain or user will be defined as channel variables when there is a call to user or when there is an inbound calls from that user.” Needs the freeswitch the mod_directory for this? I think not. What do I wrong? Thanks a lot!

originate local extension with mod_vlc into conference -> window not available
by Sebastian Denz 14 Sep '16

14 Sep '16

Hi, i want to combine audio from a sip client and video from an external ip-webcam into one outgoing call... I use mod_vlc to integrate the webcam into my dialplan like this: <extension name="video1" continue="true"> <condition field="destination_number" expression="^101$"> <action application="answer"/> <action application="playback" data="vlc://rtsp://user:pass@192.168.23.101:554/axis-media/media.amp?videocodec=h264&resolution=640x480"/> </condition> </extension> When i call 101 from a video capable client everything works fine! My current approach is to add the caller and the video extension in a conference and add then add the target extension to the conference. But when i try to add the video extension to a conference with originate loopback/101 &conference(301) the console shows: ... VLC: window not available VLC: Cannot create primary surface VLC: standard input is not a TTY see https://pastebin.freeswitch.org/view/a83b47ba for a full console log. It seems that the conference doesnt accept the output of playback/mod_vlc?! When i run freeswitch in foreground the video is displayed in ascii style directly in the freeswitch console ;) I tried it with 1.6.10 and git master... To me this feels like a bug?! But of course i would appreciate suggestions on other approaches too! Regards, Sebastian

Transfer in a Conference
by Colin Morelli 13 Sep '16

13 Sep '16

Hey again, >From looking through the source (and some light experimenting), it looks like blind transfers don't work unless the call is bridged. This means they don't work in a conference. That makes sense (the behavior would be undefined). However, I have a case in which I want this behavior, and am looking to see if anyone has done anything similar. Say two people join a call together, then a third gets added. When the third is added, all participants are moved into a conference. Now, #3 drops off, and it's just 1 and 2 again. It doesn't seem like there's any straight forward way of allowing 1/2 to initiate blind transfers, is that right? Has anyone else encountered this issue? Should I just be dynamically pulling people out of and adding them back into conferences in this case? Ideally, there'd be a way to specify conference transfer behavior such that when in a conference, blind transfers can still work so long as there are exactly two people in that conference. Would this be a welcome addition? Best, Colin

Redirect to another FS Instance
by Colin Morelli 13 Sep '16

13 Sep '16

Hey all, I tried searching through mailing list archives for this and it seems like I was able to find some related questions but they were either unanswered or different enough that it felt worth asking again. I have a distributed FS setup, and I'm trying to allow for transferring calls between two FS instances. For example, a call comes in to FS1, gets answered, goes through a few dial plan applications and then needs to be bridged into an active call (or conference) on FS2. I'm looking to figure out the best way to redirect that call to FS2 such that FS1 is neither in the signaling nor media path after the redirect. In this case, I have Kamailio in front of FS. Is uuid_simplify the answer here? Or is there another best practice for this? Thanks in advance. Best, Colin

Getting fail2ban working properly
by Don Hawkins 13 Sep '16

13 Sep '16

Morning! I've followed all instructions here, 10 times over now: https://freeswitch.org/confluence/display/FREESWITCH/Fail2Ban Then I type iptables -L f2b-freeswitch iptables: No chain/target/match by that name. It keeps saying it's not there, but I did add it, is there something I'm missing?

Interacting with another session
by Oleg Stolyar 12 Sep '16

12 Sep '16

Hi guys, Is there a way to interact with another session from Lua if you know that session's uuid? I found JS documentation that says you can do new Session(uuid) but when I try that from Lua, I get errors. When tried this: otherSession = new freeswitch.Session(uuid) otherSession was null. Hopefully I am missing something obvious.
