Hi Duvid Thanks for your suggestion, yes, that is one way of achieving it. However, our application layer is currently stateless. This allows us to have mulitple instances of it for HA, and also avoids any issues with stale state. We currently implement some custom features which do require holding conference state, and we are storing this on FreeSWITCH in the call sessions associated with the conference, which is obviously not ideal and becoming unwieldy as we develop more features. Therefore being able to store state on the conference object would be really helpful to us.

Hi Michael Thanks for looking at this - I have submitted a patch in FS-6559. Let me explain the reason that the feature would be useful to us. We have an application layer that provides customer specific conference features via mod_conference. We wish to further develop this to provide potential features such as : Questions and Answers : guests in lecture mode press some dtmf to indicate they wish to ask a question, and the chair presses some dtmf to manage the queue and unmute the questioner. Chair greeting : the chair can record a personal greeting message which is played to guests when they join. Security Passcode : the chair can dynamically set a further PIN on the conference instance via DTMF. Chair privacy : a chair can invoke privacy via some DTMF so all guests are put on hold, and only chairs can speak. And others. All of these features will require us to store state relevant to the conference instance. It would make life a lot easier if we could store this state as custom variables on the conference object via the mod_conference api.

CallerID withheld problem
by Alex Lake 28 May '14

28 May '14

Hello there.... One of our carriers has changed their signalling today and its resulted in some strange behaviour through our Freeswitch box. The change was that the P-Asserted ID has changed format to have a "+44" at the beginning - it used to be in the national format (eg. "02070601234"). The problem manifests itself further down the chain (the FS box forwards to an Asterisk box which forwards to a legacy system using E1's and Aculab cards). For some reason the E1 interprets the signalling as withheld caller id. Message Header is: Max-Forwards: 69 Session-Expires: 3600;refresher=uac Min-SE: 600 Supported: timer, 100rel To: <sip:448700802332@213.239.197.41> From: <sip:02070604380@217.145.67.2>;tag=3609589914-358461 P-Asserted-Identity: <sip:+442070604380@193.113.183.202> Call-ID: 3560925-3609589914-358457(a)MSX1.mydomain.com CSeq: 1 INVITE Allow: CANCEL, ACK, INVITE, BYE, OPTIONS, REGISTER, NOTIFY, INFO, REFER, SUBSCRIBE, PRACK, UPDATE, MESSAGE, PUBLISH Via: SIP/2.0/UDP 217.145.67.2:5060;branch=z9hG4bK630bccab557da527f8875b902c88fb6b Contact: <sip:02070604380@217.145.67.2:5060> Content-Type: application/sdp Accept: application/sdp Content-Length: 373 I forward this on as: Via: SIP/2.0/UDP 213.239.197.41;rport;branch=z9hG4bKm3jHajt7g1gaa Max-Forwards: 68 From: "02070604380" <sip:02070604380@213.239.197.41>;tag=57cmagKg0yctN To: <sip:448700802332@89.202.128.200> Call-ID: 81dbf634-5ad9-1232-1f90-d43d7ee2fdec CSeq: 59964493 INVITE Contact: <sip:mod_sofia@213.239.197.41:5060> User-Agent: FreeSWITCH-mod_sofia/1.2.23+git~20140319T002132Z~b96946822d~64bit Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: timer, path, replaces Allow-Events: talk, hold, conference, presence, dialog, line-seize, call-info, sla, include-session-description, presence.winfo, message-summary, refer Privacy: none Content-Type: application/sdp Content-Disposition: session Content-Length: 207 X-FS-Support: update_display,send_info P-Asserted-Identity: "02070604380" <sip:02070604380@213.239.197.41> I don't know if the SIPerati can discern anything from this. I could pastebin the pcap file if that would be useful. But the angle might be for me to tell FS to give calls a sip_cid_type of "none". But I don't quite undersrand from the wiki (https://wiki.freeswitch.org/wiki/Variable_sip_cid_type) where I should put this. The current dialplan is: <extension name="ajl-test2"> <condition field="destination_number" expression="^44"> <action application="privacy" data="no"/> <action application="log" data="INFO caller_id_number 0${caller_id_number:3}"/> <action application="export" data="origination_caller_id_number=0${caller_id_number:3}"/> <action application="bridge" data="sofia/internal/${destination_number}(a)89.202.128.200"/> </condition> </extension> Note the hack to change callerid from +44xxx... format to 0xxx... has been replaced by a Lua script that handles it a bit more cleanly. But that "privacy" setting doesn't seem to be enough. Any ideas or suggestions for more diagnostics?

Changing bitrate of conference recording file
by Karol Matuszewski 28 May '14

28 May '14

Hi, I see the default values in conference.conf.xml allow to create a recording wav file with parameters: PCM 8000Hz mono 128Kbps I can modify the file using codec after recording. Is it possible to change the value of bitrate before I start recording, using some parameter? -- Regards, Karol Matuszewski

FreeSWITCH Week in Review(Master Branch) May 18th-24th
by Kathleen King 27 May '14

27 May '14

Hello, again. This passed week in the FreeSWITCH master branch we had 37 commits. We saw the addition of a new module, mod_graylog2, which when asked about the module the author, Chris Rienzo, said "Basically, mod_graylog2 allows FS to send logs to a graylog2 server in its native log format: http://graylog2.org/gelf . This GELF implementation is simplified in that I didn't implement compression or chunking, though you still get logs up to around 8192 bytes (minus any fields and JSON overhead). This is an improvement over the 1024 byte limit of syslog. If anybody is interested in adding compression or chunking, feel free to send patches! In addition to supporting larger logs, we are also able to structure the logs such that fields like call UUIDs are easily searchable without having to write a bunch of extractor regexes. We're not yet sure how well graylog2 will scale for us, but the logging code was simple enough to implement in an afternoon that it's worth a try."

problem with wss
by Jamie McClelland 27 May '14

27 May '14

Hi all - I'm very excited to see support for websockets in 1.4.4! However, I'm having trouble getting wss working. When I enable it, by adding the following to internal.xml: <param name="wss-binding" value=":7443"/> I get the following error when I reload mod_sofia: 2014-05-27 09:24:47.910948 [ERR] sofia.c:2778 Error Creating SIP UA for profile: internal (sip:mod_sofia@209.234.253.18:5060;transport=udp,tcp) The likely causes for this are: 1) Another application is already listening on the specified address. 2) The IP the profile is attempting to bind to is not local to this system. When I comment out the wss line, the error goes away. Strange... 209.234.253.18 is local to the machine, and I'm specifying 7443 as the wss bind IP, not 5060 (which is specified as the "sip_port" in the internal.xml file). If I change the sip_port to a different number, I get the error, but it specifies the new sip_port. Also, accordig to lsof, port 7443 is not in use. I have ws enabled without problems. Here are the only differences between my sip_profile directory and the vanilla conf one: 0 paul:/etc/freeswitch# diff -ur /usr/share/freeswitch/conf/vanilla/sip_profiles/ /etc/freeswitch/sip_profiles/|less Only in /etc/freeswitch/sip_profiles/external: mfpl-voicepulse.xml diff -ur /usr/share/freeswitch/conf/vanilla/sip_profiles/internal.xml /etc/freeswitch/sip_profiles/internal.xml --- /usr/share/freeswitch/conf/vanilla/sip_profiles/internal.xml 2014-05-22 14:39:26.000000000 -0400 +++ /etc/freeswitch/sip_profiles/internal.xml 2014-05-27 09:29:29.000000000 -0400 @@ -196,7 +196,7 @@  <param name="tls-sip-port" value="$${internal_tls_port}"/>  -  + <param name="tls-cert-dir" value="/etc/freeswitch/certs"/>  <param name="tls-passphrase" value=""/>  @@ -304,7 +304,7 @@  -  + <param name="ws-binding" value=":5066"/>   Any suggestions? jamie p.s.
