5-for-1 review request for FS-3899 (mod_xml_curl error detection)
by Cal Leeming [Simplicity Media Ltd] 10 May '13

10 May '13

Hello, In line with the 5-for-1 approach mentioned a few months ago, I have triaged FS-3964, FS-4211, FS-4211, FS-4891 and FS-5154. In return, could a core dev please take a moment to look at this ticket: http://jira.freeswitch.org/browse/FS-3899 This started off as a discussion about making FS wait until a remote web server is available before booting up, however I've added some extra comments on a different approach that could be used. My suggestion is to add additional functionality to mod_xml_curl that allows you to define an on_failure event, which then executes any script of your choice.. you can then implement your own logic in the script. This would allow you to detect mod_xml_curl problems, and stop your FS instance from being in a 'semi loaded' state in the event of a temporary web server problem. Any thoughts/feedback would be much appreciated. Many thanks Cal

looking for a way to do appointment reminders
by Brandon Coale 10 May '13

10 May '13

Hello, I am in the research phase for the following project and am researching what options are available. My health care organization is looking for a way to do appointment reminders. We currently have staff members who spend part of each day manually calling patients to remind them of their upcoming appointments, and we would like to automate this process. Our electronic health record software would provide such information as the patient's name, phone number, and day and time of the appointment, and FreeSWITCH could take this information and place an automated call to the patient. We would like the reminder call to use text-to-speech to personalize the call, such as "We have an appointment reminder for [first name]. The appointment is on [date] at [time]. I am wondering if anyone has experience with using FreeSWITCH for this type of application, and would be willing to share any details of how you implemented it? I am interested in any ideas, from very simple to feature-rich. We would be doing a new installation of FreeSWITCH for this purpose, so we could use any version of FreeSWITCH or any operating system you would recommend. Thank you! Brandon

Analysis of Cisco 7940, SIP ALG and NAT traversal problems
by Cal Leeming [Simplicity Media Ltd] 10 May '13

10 May '13

Hello all, I've seen the matter of NAT traversal come up several times, but very few people go into detail about some of the specific problems and how/why they happen. So today I spent a few hours doing a write up of an on-going problem we've had with the Cisco 7940 phones, and a variety of routers. This article goes into quite a bit of detail, giving a breakdown of some of the specific problems we were having, and some of the ways you can resolve it. Although not strictly FreeSWITCH related (despite the FS reference), I'm hoping that this write up will help others understand some of the NAT traversal problems; http://blog.simplicitymedialtd.co.uk/476/analysis-of-cisco-7940-sip-alg-and… Thanks Cal

set_tts_params
by Alex Lake 10 May '13

Can anyone tell me in which version of Freeswitch set_tts_params function was introduced? Although set_tts_parms is now deprecated, I seem to have some 1.2 installations that don't have it!

how Curl post dynamic variables
by rajat 10 May '13

10 May '13

Hi I am new to freeswitch and i am trying to integrate one php application with freeswitch. Purpose is freeswitch will send the user dialed (dtmf numbers) as input to this php application and in return it will send the response back. Dialplan which I have written for this is <extension name="inte"> <condition field="destination_number" expression="^9199$"> <action application="read" data="0 9 $${base_dir}/sounds/en/us/callie/conference/8000/input-string.wav res 60000 #"/> <action application="sleep" data="2000"/> <action application="export" data="new=${res}"/> <action application="sleep" data="2000"/> <action application="say" data="en name_spelled iterated ${new}"/> <action application="curl" data="http://192.168.10.27/index.php post id=${new}" inline="true"/> <action application="sleep" data="2000"/> <action application="speak" data="flite|slt|${curl_response_data}"/> <action application="info"/> <action application="speak" data="flite|slt|Thanks for your query"/> <action application="lua" data="helloworld.lua ${curl_response_data}"/> </condition> </extension> Now http://192.168.10.27/index.php this is a url on which i am sending my requests. Problem here is curl is not taking variable in the post. If instead of ${new}, i put some random static value like 256, then it is working perfectly fine but I want my users to input the values. Kindly suugest some way via which I can post variables in curl url -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/how-Curl-post-dynamic-variabl… Sent from the freeswitch-users mailing list archive at Nabble.com.

Re: [Freeswitch-users] Freeswitch silent crash
by Mr Nathan Downes 09 May '13

09 May '13

I appear to have fixed this on mine, when I moved everything over to the new server (12.0.4) I forgot the ulimit stuff in the init.d script and threading=0 in the odbc file for postgres.. Since these have gone in I haven't had a crash.. I also moved up to current head from stable.. not sure if this helps. From: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Richard Zheng Sent: Monday, 29 April 2013 4:08 AM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] Freeswitch silent crash I have this problem too. There are several similarity here. There is no core dump even with suid_dumpable to 1 and other suggestions on the wiki, e.g. ulimit, change directory to /tmp in FS start script. Using ubuntu latest 12.04, running as non-root, lua to generate dialplan and control routing. The most troubling/headache is that there is no core dump when crash. I understand that there is no much to do without it... Any suggestion is appreciated!

Dead channels in freeswitch
by Farrukh Ali 09 May '13

09 May '13

Hi, I need some help, there is an issue in Freeswitch with SIP clients, when a call is not hung up properly Freeswitch does not close its RTP channels, and it starts to get load on bandwidth after too many dead channels are generated, Improper hang up means if during call sip client went out of the range of WiFi, the client i.e SipDroid shows call hang up but freeswitch continues to send voice packets. Kindly reply

Call Hangup cause 'None'
by Rob Moore 09 May '13

09 May '13

Hi Guys, I was wondering if someone could clear up exactly what the hangup case 'none' means? It started appearing after an upgrade to the latest version of Freeswitch (from a very very old 1.0.0 version) in place of the usual "ALOTTED_TIMEOUT" outcomes we would expect to see from and unanswered call. I would have considered this a simple reclassification of the call result however we are still getting a few "ALOTTED_TIMEOUT" mixed in with these "none's" which makes me wonder if its actually the symptom of another problem I'm not seeing yet. Any advice on what none means and why it appears in our CDRS would be greatly appreciated! Thanks Rob
