Re: [Freeswitch-users] illegal instruction
by Andrew 13 Mar '15

Thanks, I looked and its set to "NOT SET". I do know the CPU is a AMD that is having an issue. Not sure if the other server is an Intel or not. Andrew From: Andrew [mailto:aademattia@Comcast.net] Sent: Sunday, March 8, 2015 3:36 PM To: 'FreeSWITCH Users Help' Subject: illegal instruction Hi, I have an odd issue. I was going to run out of the box FreeSWITCH on a windows server and just by double clicking on freeswitch.exe I get a crash. When I did a debug I found it was illegal instruction error. If I remove mod_spandsp The program starts up fine. I then try to do a tone detection and then the program crashes again. What would cause the same release code to work on one server but crash on another server? Andrew

failover in freeswitch dialplan using | or lcr
by Jason Holden 13 Mar '15

13 Mar '15

Hi, If I send an invite for a call and don't receive a response to the initial invite message how can I force FS to try the next route right away? Here is one of my lcr dialplan chunks. <condition field="destination_number" expression="^(.*)$"> <action application="set" data="continue_on_fail=true"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="domain_name=$${domain}"/> <action application="set" data="instant_ringback=true"/> <action application="ring_ready" /> <action application="set" data="ringback=${us-ring}"/> <action application="set" data="transfer-ringback=${us-ring}"/> <action application="lcr" data="$1 inbound"/> <action application="set" data="bypass_media=true"/> <action application="bridge" data="${lcr_auto_route}"/> </condition> </extension> All advise is welcome, thanks.

by Vladimir Getmanshchuk 13 Mar '15

13 Mar '15

Hello Everyone! I have two installations of FS with absolutely identical configurations. Both has SIP profiles with proxy-media enabled. But on freeswitch@internal> version FreeSWITCH Version 1.4.15~64bit ( 64bit) I have values in read_codec/write_codec variables at CDRs: "read_codec":"PROXY","write_codec":"PROXY" but on another one freeswitch@internal> version FreeSWITCH Version 1.4.5~64bit ( 64bit) I have: "read_codec":"G729","write_codec":"G729", "read_codec":"PCMA","write_codec":"PCMA", etc... So Why? -- Yours sincerely, Vladimir Getmanshchuk

Fail to ban rule for detecting INVITES with no challenge
by Peter Steinbach 12 Mar '15

12 Mar '15

Hello, we receive a number of Invites from certain IPs, who want to break into our system and call external premium rate numbers Unwanted registers we can block already, but we still have the issue to block specific invites from fraudulent IPs inside the iptables firewall. In the Freeswitch log we see: 2015-03-12 16:54:38.381552 [NOTICE] switch_channel.c:1055 New Channel sofia/internal/149(a)10.11.12.13 [167bb9ee-c8d0-11e4-9f31-b39e581405c5] 2015-03-12 16:54:38.381552 [DEBUG] switch_core_session.c:1061 Send signal sofia/internal/149(a)10.11.12.13 [BREAK] 2015-03-12 16:54:38.381552 [DEBUG] switch_core_session.c:1061 Send signal sofia/internal/149(a)10.11.12.13 [BREAK] 2015-03-12 16:54:38.381552 [DEBUG] switch_core_state_machine.c:472 (sofia/internal/149(a)10.11.12.13) Running State Change CS_NEW 2015-03-12 16:54:38.381552 [DEBUG] sofia.c:8841 sofia/internal/149(a)10.11.12.13 receiving invite from 155.94.64.26:5076 version: 1.5.15b git 82f267a 2015-02-16 22:59:55Z 64bit 2015-03-12 16:54:38.381552 [DEBUG] sofia.c:9008 IP 15.194.164.26 Rejected by acl "domains".

The IP 10.11.12.13 is the (anonymized) IP of our server. The point here is: 15.194.164.26 is sending an INVITE, Freeswitch then sends "authentication required". Freeswitch then logs this entry with "Abandoned" (see last line above) and that's it. So Is there any way to make Freeswitch show up a log line with the fraudulent IP 15.194.164.26 and some text like "abandonned"? Example for extending a current log line 2015-03-12 16:54:48.461568 [WARNING] switch_core_state_machine.c:572 167bb9ee-c8d0-11e4-9f31-b39e581405c5 sofia/internal/149(a)10.11.12.13 Abandoned for IP 15.194.164.26 This would enable us to process this entry with fail2ban and block this IP in the Firewall. Any other hint is welcome. -- With kind regards Marvin Keil Telefaks Services GmbH mailto:lists (att) telefaks.de Internet: www.telefaks.de

ESL object taking large memory
by DP Siddharth 12 Mar '15

12 Mar '15

Hi All, I am working on python/esl based server. We are seeing memory getting increase by ~6.5MB when con = ESLconnection() get called. We tried to cleanup this object as soon calls gets complete, but somehow we are not successful. Further looking into esl/src/include/esl.h we found #define BUF_CHUNK 65536 * 50 #define BUF_START 65536 * 100 modifying these values help in controlling python server memory growth. Can someone help me in understanding why we have this buffer size of 6.5MB? -- Thanks & Regards, D P Siddharth Director (Platform) Knowlarity Communications Ph: +919999115231 dp.siddharth(a)eng.knowlarity.com <emailID(a)knowlarity.com> *"Come together to build a lasting world-class cloud telephony company that helps businesses grow"*

Aastra 9133i phones Intercom/AutoAnswer w/FreeSWITCH
by T Fred Farmington 12 Mar '15

12 Mar '15

Hello, My current challenge is getting the AutoAnswer to work on the 9133i phones to support Intercom functionality. Within the conf/dialplan/default.xml file I am basically using the FreeSWITCH default settings <extension name = "extension-intercom"> <condition field = "destination_number" expression = "^8(1[012][0-9])|8(10[012][0-9])$">  <action application = "set" data = "dialed_extension=$1"/> <action application = "export" data = "sip_auto_answer=true"/> <action application = "bridge" data = "user/${dialed_extension}@${domain_name}"/> </condition> </extension> The AutoAnswer is working on the single Aastra 6731i phone that I have in the system, but not on any of the 9133i phones. This is in spite of both phone models have the Auto-Answer parameter set in their individual internal configurations. 9133i: Incoming Intercom Settings -- Auto-Answer -- Enabled 6731i: Incoming Intercom Settings -- Auto-Answer -- Enabled NOTE - the 9133i extension's will ring, but not go into the AutoAnswer/Speaker/Intercom mode While searching the web for an answer I came across an old posting (Feb 11, 2011) where Tim St. Pierre indicates that he has a relatively large FreeSWITCH phone system incorporating a number of Aastra models. He goes on to say that he has Intercom calls (auto-answer to speaker phone) working on the 9133i phones (among others) I'd appreciate any advice anyone might have so that I can get the FreeSWITCH Intercom auto-answer working on the 9133i phones as well. Thanks, TF

blf status stress testing
by Raphael Lechner 12 Mar '15

12 Mar '15

Hi, We have the problem that on different installations the blf keys in combination with yealink phones don’t always show the correct status, sometimes ringing or busy is not shown. The installations are relative small from 3 to 80 Phones. We still have the V72 Version of firmware on the phones and not all installations have the current 1.4.15 version of FreeSWITCH. I’m trying to build some kind of stress test environment to try to reproduce the issue do identify if the problem is resolved with the new phone firmware and FreeSWITCH version or to identify what is going wrong. Can someone recommend tools for stress testing the blf keys? Thank you, Raphael

Chrome 42 Beta (on Windows) not working with FreeSWITCH
by Oleg Stolyar 11 Mar '15

11 Mar '15

Hi guys, I just got Chrome 42 beta and it does not work with FreeSWITCH. I am getting this error on FS: 2015-03-10 19:04:12.272683 [ERR] switch_rtp.c:2800 audio DTLS packet not written I tested it with the FS Verto test site and it also does not work. https://webrtc.freeswitch.org/verto/index.html#page-main Is this a known issue? Of course 42 Beta also does not recognize Java for me, so hopefully it's just a crappy build and Google will fix it but my concern is that other WebRTC test sites still work, so should we look into this in case it's not fixed by the time Chrome 42 becomes stable?

xml_cdr encoding issues
by Assaf Dahary 11 Mar '15

11 Mar '15

Hi, I have installed a fresh FS on a DigitalOcean VPS (CentOS 6.5 64bit). FreeSWITCH Version 1.5.15b+git~20150303T230402Z~86c68d906a~64bit (git 86c68d9 2015-03-03 23:04:02Z 64bit) I'm using mod_cml_cdr to process call logs into DB using a PHP script ($xml = simplexml_load_string($xml_string);) The problem is that the xml parsing is failing because the generated POST XML CDR string received on my web is NOT url-encoded as should be. I verified that encoding is enabled: <param name="encode" value="true"/> (see full conf file below). This un-encoded line from the posted xml CDR is one example for what is causing the xml parsing error: <sip_full_from>"99252627" <sip:1234@11.11.11.11>;tag=y3Xr3g6HZZtBQ</sip_full_from>. On other FS I get it encoded with no xml errors: <sip_full_from>%3Csip%3A1234%40abc.com%3E%3Btag%3DnQGk6NEXS0yYrSeyIYCbrXmge7 80R7J4</sip_full_from> I've reinstalled all PHP/XML/CURL related modules with no help. I also tried to post to my other FS web server thinking that the local FS web is decoding and then passing to the php xml script - still with no help. Any tip/help/advise will be appreciated. Regards Assaf This is my xml_cdr.conf.xml file: <configuration name="xml_cdr.conf" description="XML CDR CURL logger"> <settings>           <param name="log-dir" value=""/>   <param name="log-b-leg" value="false"/>   <param name="prefix-a-leg" value="true"/>  <param name="encode" value="true"/>         </settings> </configuration>
