ESL socket outbound: the execution of answer has not effect
by Stephen Wilde 22 Feb '11

22 Feb '11

I'm running an esl socket outbound application and I have a systematic problem: in a particular situation, the execution of answer on incoming call has no effect. This happens always when (and only in this case): 1. an incoming call is received (legA) and via dialplan I send the call to my socket outbound application 2. I make an outbound call with originate (legB) 3. I receive a CHANNEL_PROGRESS_MEDIA on legB 4. I do a "pre_answer" on legA 5, I do a "uuid_bridge" between legA and legB in this phase, legA can hear the progress tone coming from legB (an in-band ringback) 5. legB answer the call and I receive a CHANNEL_ANSWER on legB 6. I do an execute of "answer" on legA This "answer" has no effect! I do both pre_answer and answer specifying the UUID parameter (sendmsg <uuid>), obviously using legA uuid . I do the bridge specifying inbound uuid as first parameter and outbound uuid as second parameter: uuid_bridge <inbound_uuid> <outbound_uuid> In fs_cli I see: [WARNING] switch_ivr_bridge.c:1412 reversing order of channels so this will work! To me it seems that in uuid_bridge is done an inversion with my inbound/outbound channels and because I do an answer to the incoming uuid, probably (due to the inversion) is treated as outbound so the answer is ignored. Attached to this email the .pcap file related to tcp traffic between Freeswitch and my socket outbound application where at time 8.562639 there is my sendmsg with the answer. Stephen

The call dropped prematurely error on txfax
by rex.alex 22 Feb '11

22 Feb '11

Hello, I am testing the FreeSWITCH mod_spandsp module. I have got a gateway registered in FreeSWITCH which supports fax and using the following command to send the fax, but It always ended up with the "result (49) The call dropped prematurely" error. Also if I remove fax_enable_t38 variables, it's giving "Reinvite Codec Error!". I have pastebin the entire log in http://pastebin.freeswitch.org/15394. originate {absolute_codec_string='PCMU,PCMA', fax_enable_t38=true,fax_enable_t38_request=true}sofia/gateway/Pulse/1XXXXXXXXXX &txfax(/var/www/html/faxtest/docs/15Feb2011103600.pdf.tiff) Please assist. Thanks, Rex -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/The-call-dropped-prematurely-… Sent from the freeswitch-users mailing list archive at Nabble.com.

Updating callee info when using application intercept
by mayamatakeshi 22 Feb '11

22 Feb '11

Is there any way to update the callee number/name that would show up in a terminal that gets a dialplan to intercept a channel? I am trying with this: <action application='set' data='sip_callee_id_number=12341234'/> <action application='set' data='sip_callee_id_name=abcdabcd'/> <action application='send_display' data='fffff'/> <action application='answer'/> <action application='intercept' data='Some-UUID'/>" But I don't see any changes (I was expecting that it might change the username in the header To or cause FS to send some extra SIP message before or after "200 OK"). r, takeshi

Enterprise bridge, groups and "follow me" dialplan
by Dmitry Bely 22 Feb '11

22 Feb '11

I am trying to implement the following bridging scenario: <action application="set" data="call_timeout=30"/> <action application="bridge" data="group/group1@domain,[leg_delay_start=10]group/group2@domain"/> ... i.e. all phones in group1 should ring for 10 seconds and if nobody answers group1+group2 rings for additional 20 seconds. That almost works, but only the first phone rings in either group: [WARNING] switch_ivr_originate.c:2339 Only calling the first element in the list in this mode. Surely I need enterprise bridge: <action application="bridge" data="group/group1@domain:_:[leg_delay_start=10]group/group2@domain"/> but now there is no correct caller id and no leg delay. Caller id can be restored with: <action application="bridge" data=" <origination_caller_id_name=${caller_id_name},origination_caller_id_number=${caller_id_number}> group/group1@domain:_:[leg_delay_start=10]group/group2@domain"/> (is this a bug or design decision?), but what to do with leg delay? [leg_delay_start=10] is simply ignored there. - Dmitry Bely

How to create a C++ application (project), that can code FS C code function?
by Frankie Yiu 22 Feb '11

22 Feb '11

Hi there, I am new to FreeSwitch and I would like to implement a C++ application / mod that would do some analysis of RTP packets. I would like to ask what mod I should use as a template to create my C++ project so that I can access the core FreeSwitch APIs / functions, since they are in C language? I know under Endpoints, there are 2 MODs that are using C++ code (mod_h323 and mod_opal), but I don't know if I should implement the same way if I am creating an "application" instead of "endpoints". Please kindly let me know if there is any special / required function that I need to implemented in C++ code. Thanks in advance. Frankie

escape in originate
by Seven Du 22 Feb '11

22 Feb '11

I want to put tone_stream in dialstring but don't know how to escape the comma. originate {some_var='tone_stream://%(2000,4000,440.0,480.0);loops=1'}portaudio/auto_answer &echo 2011-02-20 19:13:09.516139 [DEBUG] switch_ivr_originate.c:1971 variable string 0 = [some_var=tone_stream://%(2000] 2011-02-20 19:13:09.516139 [DEBUG] switch_ivr_originate.c:1971 variable string 1 = [4000] 2011-02-20 19:13:09.516139 [DEBUG] switch_ivr_originate.c:1971 variable string 2 = [440.0] 2011-02-20 19:13:09.516139 [DEBUG] switch_ivr_originate.c:1971 variable string 3 = [480.0);loops=1] There's a work around but it's not elegant. http://lists.freeswitch.org/pipermail/freeswitch-users/2010-September/06275… Actually we may not need to escape the comma, the parser should keep reading until found the second quote. Would this need a patch? Thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn

bridging?
by Neil Patel 22 Feb '11

22 Feb '11

Hi Folks, newbie question: I have a simple dialplan that takes calls to an extension and executes a lua app: *<extension name="incoming">* * <condition field="destination_number" expression="^7777$">* * <action application="lua" data="lua/app.lua" />* * </condition>* * </extension>* * * >From the same extension I am initiating calls from FS to endpoints and executing another lua app. What I want to do is connect (bridge?) those outbound calls to app.lua. From FS perspective this call should now look like it was initiated by the caller to 7777. Is this what call bridging is? What commands/wiki page should I be looking at to do this? Thanks in advance, Neil

xml_curl and gateways
by Peter P GMX 21 Feb '11

21 Feb '11

According to http://wiki.freeswitch.org/wiki/Mod_xml_curl I'v tried to set up gateways dynamically, but I do net get it to work: I always get : "Invalid profile" My assumptions for a right xml answer back to FS are as follows, but I think at least one of it is false: 1. ) I start with <document type='freeswitch/xml'> <section name='configuration'> <configuration name='sofia.conf' description='RailsAdditionalConf'> 2.) I do not want to change settings, so I do NOT add a <settings> tag 3.) I want to enhance an existing profile, so I add a profile tag (<profile name='external'>) 4.) I assume that I can have an existing profile "external" in the xml conf files and can mix additional parts dynamically into the same profile 5.) Within the profile I want to add gateways, so I add a gateway tag (<gateways>) 6.) Then I add the gateways 7.) I add the closing tags Which one of the assumptions if wrong? The request I receive is as follows: {"key_name"=>"name", "action"=>"directory", "tag_name"=>"configuration", "key_value"=>"sofia.conf", "controller"=>"xml_curls", "hostname"=>"freeswitch", "section"=>"configuration"} I only answer once at startup with the follwing: <document type='freeswitch/xml'> <section name='configuration'> <configuration name='sofia.conf' description='RailsAdditionalConf'> <profile name='external'> <gateways> <gateway name="freeswitch2"> <param name="username" value="1007"/> <param name="realm" value="192.168.0.56:5061"/> <param name="password" value="xxxx"/> <param name="proxy" value="192.168.0.56"/> <param name="expire-seconds" value="30"/> <param name="register" value="true"/> <param name="register-transport" value="tls"/> <param name="retry-seconds" value="30"/> </gateway> </gateways> </profile> </configuration> </section> </document> Does anybody have a correct XML answer for a gateway and can post it? Best regards Peter
