It works, but now since it's missing the first frame, the resulting video is only partial, showing new bits.

GSMopen and Embedded Combined Devices
by Komar, Jason 18 Jan '12

Hi, I'm thinking about giving GSMopen a try and am wondering if anyone has a good source and recommendation for an embedded combined device for use with it? I have done some web searching, but must not be using the best search terms. Thanks, Jason Komar

Variable in dialplan
by Miha Zoubek 18 Jan '12

18 Jan '12

Hi, I need a little help about passing variable between dialplans. I have created one default diaplan. In this dialplan a have set: <action application="execute_extension" data="check special numbers XML default"/> In check special numbers XML there is a condition (<condition field="destination_number" expression="^check special numbers$" >) and than <action application="execute_extension" data="special numbers XML default"/>. In special numbers XML I have a condition and if this condition is right the variable $test is set to 112. SO in default dialplan after all this is set must default dialplan execute this <action application="bridge" data="sofia/external/386${test}(a)xx.xxx.xxx.xxx"/> where ${test} should be variable from special numbers XML. Why the value of variable is not passed? Thanks! -- Best regards / Lep Pozdrav Miha Zoubek Softnet d.o.o.

Question about the future of mod_nibblebill
by Carlo Dimaggio 18 Jan '12

18 Jan '12

Hi all, I'm thinking about a development of a custom prepaid application based on mod_nibblebill (that is very interesting). I'm wondering about the status and the future of this module in order to understand if this is the better way to achieve the aim of the project. I have seen in the mod_nibblebill source code this notes: * TODO: Fix what happens when the DB is not available * TODO: Fix what happens when the DB queries fail (right now, all are acting like success) * TODO: Add buffering abilities * TODO: Make error handling for database, such that when the database is down (or not installed) we just log to a text file * FUTURE: Possibly make the hooks not tied per-channel, and instead just do this as a supervision style application with one thread that watches all calls Does the developers think to continue supporting the module (not only bugfix but new features)? I'm sorry for the particular question but I wouldn't do errors at this stage of the project. Best Regards,

Stacked conditions are not acting like logical AND
by Herman Griffin 18 Jan '12

18 Jan '12

Hello Freeswitchers, I'm using stacked condition that are supposed to behave line logical AND operators. The call trace has been separated in to two section. The first section corresponds to the first set of stacked conditions in my dialplan and the second section corresponds to my second set of stacked conditions. The second condition in the second set of stack condition evaluates to FAIL (false). However the 'action' that are wrapped are still being exacuted. I expect the 'anti-action' to execute when any of the AND operands evaluates to FAIL. Note: I'm using break=never because I don't want a failed condition to break me out of the extension. There are multiple condition blocks in the extension. Regardless of whether break being set to never, it seems that the wrapped actions should not execute unless all conditions evalute to PASS (true) Can someone help point out my mistake? Thank you, Herman Griffin ------------------------------------ This is my call trace: Dialplan: sofia/external/Unknown(a)72.37.252.18 Regex (PASS) [emergency] ${open}(true) =~ /^true$/ break=never Dialplan: sofia/external/Unknown(a)72.37.252.18 Regex (FAIL) [emergency] ${emergency_call}() =~ /^true$/ break=never Dialplan: sofia/external/Unknown(a)72.37.252.18 Regex (PASS) [emergency] ${sip_gateway}(1006_7217) =~ /^1006_7217$/ break=never Dialplan: sofia/external/Unknown(a)72.37.252.18 Regex (FAIL) [emergency] ${emergency_call}() =~ /^true$/ break=never Dialplan: sofia/external/Unknown(a)72.37.252.18 Regex (PASS) [emergency] ${db(select/emergency/autoanswer)}(1) =~ /^1$/ break=never Dialplan: sofia/external/Unknown(a)72.37.252.18 Action set(call_timeout=60) Dialplan: sofia/external/Unknown(a)72.37.252.18 Action set(effective_caller_id_name=${regex(${caller_id_name}|^Emerg(_.*)$|Auto%1)}) Dialplan: sofia/external/Unknown(a)72.37.252.18 Action set(autoanswered=true) Dialplan: sofia/external/Unknown(a)72.37.252.18 Action answer() Dialplan: sofia/external/Unknown(a)72.37.252.18 Action set(group_confirm_file=/usr/local/freeswitch/sounds/en/us/callie/emergency/press_to_accept.wav) Dialplan: sofia/external/Unknown(a)72.37.252.18 Action set(group_confirm_key=1) Dialplan: sofia/external/Unknown(a)72.37.252.18 Action bridge(user/1000@${domain_name},sofia/gateway/1006_7217/${mobile_number}) ------------------------------------ This is the corresponding dialplan: <condition field="${open}" expression="^true$" break="never"/> <condition field="${emergency_call}" expression="^true$" break="never"> <action application="set" data="session_in_hangup_hook=true"/> <action application="set" data="api_hangup_hook=python emergency.hangup"/> </condition> <condition field="${sip_gateway}" expression="^${default_provider}$" break="never"/> <condition field="${emergency_call}" expression="^true$" break="never"/> <condition field="${db(select/emergency/autoanswer)}" expression="^1$" break="never"> <action application="set" data="call_timeout=60"/> <action application="set" data="effective_caller_id_name=${regex(${caller_id_name}|^Emerg(_.*)$|Auto%1)}"/> <action application="set" data="autoanswered=true"/> <action application="answer" data=""/> <action application="set" data="group_confirm_file=/usr/local/freeswitch/sounds/en/us/callie/emergency/press_to_accept.wav"/> <action application="set" data="group_confirm_key=1"/> <action application="bridge" data="user/1000@${domain_name},sofia/gateway/1006_7217/${mobile_number}"/>  <anti-action application="set" data="effective_caller_id_name=${regex(${caller_id_name}|^Emerg(_.*)$|NotAuto%1)}"/> <anti-action application="set" data="call_timeout=30"/> <anti-action application="set" data="autoanswered=false"/> <anti-action application="bridge" data="user/1000@${domain_name},sofia/gateway/1006_7217/${mobile_number}"/> </condition>

sip_auto_answer auto copy to bleg
by Seven Du 18 Jan '12

18 Jan '12

Hi, I use originate {sip_auto_answer}user/1000 &bridge(user/1001) and want 1000 to be auto answered but not 1001, but it seems FS automatically copy to b-leg. I manually comment the following lines and it seems to work. // switch_channel_set_variable(nchannel, "sip_invite_params", "intercom=true"); } switch_ivr_transfer_variable(session, nsession, SOFIA_REPLACES_HEADER); // switch_ivr_transfer_variable(session, nsession, "sip_auto_answer"); would it be good to default to not copy but leave the "export" or equivalent to do that? Or should I patch to add a var to disable that? Thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)

announce count mod conference
by Rodney 17 Jan '12

17 Jan '12

the following section of mod conference does not seem to work for me. is this meant to be played for the whole room or just the user entering the room. I would like it only to work for the person entering the room to cut down on the amount of them pressing the dtmf to execute the announce count extension. it seems this is the first thing they do and I want them to not have to do that. I have set this to 0 and 1 and still no caller count announced. how may I trouble shoot this problem? thanks. when i go into an empty room it says my zerocallers.wav but nothing else if i enter a room with 1 or more callers. for announce-count Requires TTS. The system will speak the total number of callers in the conference when a new person joins, but only once the threshold specified in this parameter is reached. 5

FreeSWITCH Community Conference Call Tomorrow
by Michael Collins 17 Jan '12

17 Jan '12

Hello all! Just a reminder that we have our FreeSWITCH community conference call tomorrow. We have Moc scheduled to discuss some of the new things he's been cooking up. However, he might have to go play with his cable modem for a bit so we'll see how the schedule pans out. The agenda is here: http://wiki.freeswitch.org/wiki/FS_weekly_2012_01_18 Make a note of the upcoming conference calls. Normally I could say that we are booked solid through February, but since 2012 is a leap year we actually have a call scheduled for February 29. I'd love to hear some suggestions for a special leap-year edition of the FS community conference call! Let me know what you think. :) Thanks, Michael
