session timer - enable/disable per call
by Gabriel Kuri 06 Sep '17

06 Sep '17

Is it possible to either: a) enable/disable the session timer per call, via the dialplan? b) change the session timeout value per call, via the dialplan? Currently, it's set in the sofia profile, either: <param name="enable-timer" value="false"/> or <param name="session-timeout" value="xxx"/> However, it would be great if it could be changed/set per call. If you ask why, a particular device when it receives a re-invite mid-call decides to re-invite an already established T.38 call to PCMU which breaks the FAX transmission. Yes, this is a long fax :) Unfortunately, the vendor won't fix, so it'd be nice for these devices to be able to simply disable or set the timer to a really long time in the dialplan. Thanks ...

Does Freeswitch support RFC 4662 for BLF Resource list URI? Asterisk does: https://wiki.asterisk.org/wiki/pages/viewpage.action?pageId=30278158 They have a good overview page Kamillio does: https://kamailio.org/docs/modules/3.2.x/modules_k/rls.html Good info from Grandsteam about why to use this: http://www.grandstream.com/ sites/default/files/Resources/GXP21x0_Eventlist_BLF_Guide.pdf Same with Polycom: http://community.polycom.com/polycom/attachments/ polycom/VoIP/19112/1/Technical%20Brief%20-%20Busy%20Lamp%20Field.pdf Others have asked this question on the freeswitch users list, but responses were limited.

B-leg transfer
by David Villasmil 05 Sep '17

05 Sep '17

I have this dialplan i'd like to do, let's see if i can explain it :) I have a call coming in on 5080, which i forward to another box. When B-leg is answered, I want to disconnect the A-leg and bridge B-leg to a conference. I'm trying with the following: <extension name="Move_b_leg_to_conference" continue="false"> <condition field="destination_number" expression="^9999$"> <action application="callcenter" data="support@default"/> </condition> </extension> <extension name="Forward_to_proxy" continue="true"> <condition field="destination_number" expression="^(.*)$"> <action application="export" data="nolocal:execute_on_answer=transfer -bleg 9999@public"/> <action application="bridge" data="sofia/gateway/proxy/$1"/> <action application="hangup" data="NORMAL_CLEARING"/> </condition> </extension> The idea is to answer the call with the second extension and execute_on_answer to transfer the b-leg to extension 9999 on public, which sends it over to the conference... But this doesn't seem to be working, the call seems to be sent to 9999@public: 2017-09-04 23:09:21.243247 [NOTICE] sofia.c:8159 Channel [sofia/external/4345412121] has been answered EXECUTE sofia/external/4345412121 transfer(-bleg 9999@public) 2017-09-04 23:09:21.243247 [DEBUG] switch_ivr.c:2165 (sofia/external/ 12345(a)1.2.3.4) State Change CS_EXECUTE -> CS_ROUTING 2017-09-04 23:09:21.243247 [NOTICE] switch_ivr.c:2172 Transfer sofia/external/12345(a)1.2.3.4 to XML[9999@public@public] I've also tried doing uuid_transfer on the bleg like so: <extension name="Forward_to_proxy" continue="true"> <condition field="destination_number" expression="^(.*)$"> <action application="set" data="new_uuid=${create_uuid foo}" inline="true"/>  <action application="bridge" data="{hangup_after_bridge=true,origination_uuid=${new_uuid}}sofia/gateway/proxy/$1"/> <action application="uuid_kill" data="${uuid}"/> </condition> </extension> and also instead of uuid_transfer, i tried putting the bleg on hold like: <action application="export" data="nolocal:api_on_answer=uuid_hold ${new_uuid}"/> But is seems as soon as the aleg dies, the whole thing dies Help is much appreciated!

Channel Event Issue
by Freeswitch 04 Sep '17

04 Sep '17

Hi, since updating from FreeSWITCH 1.6.8 to FreeSWITCH 1.6.17 (Windows Server 2012 R2), the Event Socket Handler(inbound mode) sporadically stops sending Channel related Event Info. Once in this situation, the Event Socket Handler does not recover until either reset of the ESL connection by the Host that established the ESL connection or reload of mod_event_socket. Shortly before Event Socket connection drops it seems that there is a problem trying to close a channel. Example Log for failure case: Channel with uuid d9be476b-6a9d-4c96-95fb-5d8728bcc08e is never closed after leavig the conference. d9be476b-6a9d-4c96-95fb-5d8728bcc08e 2017-08-29 10:59:35.399989 [NOTICE] switch_channel.c:1104 New Channel sofia/external/149@dialin [d9be476b-6a9d-4c96-95fb-5d8728bcc08e] d9be476b-6a9d-4c96-95fb-5d8728bcc08e 2017-08-29 10:59:35.399989 [INFO] mod_dialplan_xml.c:637 Processing 149 <149>->4600 in context public d9be476b-6a9d-4c96-95fb-5d8728bcc08e 2017-08-29 10:59:35.399989 [NOTICE] switch_ivr.c:2172 Transfer sofia/external/149@dialin to XML[4600@default] d9be476b-6a9d-4c96-95fb-5d8728bcc08e 2017-08-29 10:59:35.419958 [INFO] mod_dialplan_xml.c:637 Processing 149 <149>->4600 in context default d9be476b-6a9d-4c96-95fb-5d8728bcc08e 2017-08-29 10:59:35.439966 [NOTICE] mod_dptools.c:1312 Channel [sofia/external/149@dialin] has been answered d9be476b-6a9d-4c96-95fb-5d8728bcc08e 2017-08-29 10:59:55.940144 [NOTICE] sofia.c:1012 Hangup sofia/external/149@dialin [CS_EXECUTE] [NORMAL_CLEARING] d9be476b-6a9d-4c96-95fb-5d8728bcc08e 2017-08-29 10:59:55.940144 [INFO] conference_loop.c:1469 Channel leaving conference, cause: NORMAL_CLEARING Example Log for regular case: Channel with uuid 982453be-a321-4825-a944-ecfffa715914 is closed correctly after leaving the conference): 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:55:51.340132 [NOTICE] switch_channel.c:1104 New Channel sofia/external/149@dialin [982453be-a321-4825-a944-ecfffa715914] 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:55:51.340132 [INFO] mod_dialplan_xml.c:637 Processing 149 <149>->4600 in context public 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:55:51.360126 [NOTICE] switch_ivr.c:2172 Transfer sofia/external/149@dialin to XML[4600@default] 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:55:51.360126 [INFO] mod_dialplan_xml.c:637 Processing 149 <149>->4600 in context default 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:55:51.380148 [NOTICE] mod_dptools.c:1312 Channel [sofia/external/149@dialin] has been answered 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:56:11.900321 [NOTICE] sofia.c:1012 Hangup sofia/external/149@dialin [CS_EXECUTE] [NORMAL_CLEARING] 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:56:11.900321 [INFO] conference_loop.c:1469 Channel leaving conference, cause: NORMAL_CLEARING 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:56:11.900321 [NOTICE] switch_core_session.c:1683 Session 9744 (sofia/external/149@dialin) Ended 982453be-a321-4825-a944-ecfffa715914 2017-08-29 10:56:11.900321 [NOTICE] switch_core_session.c:1687 Close Channel sofia/external/149@dialin [CS_DESTROY] The channel with uuid d9be476b-6a9d-4c96-95fb-5d8728bcc08e will still be displayed at fs_cli on request of "show channels" freeswitch@1250-0110> show channels uuid,direction,created,created_epoch,name,state,cid_name,cid_num,ip_addr,dest,application,application_data,dialplan,context,read_codec,read_rate,read_bit_rate,write_codec,write_rate,write_bit_rate,secure,hostname,presence_id,presence_data,accountcode,callstate,callee_name,callee_num,callee_direction,call_uuid,sent_callee_name,sent_callee_num,initial_cid_name,initial_cid_num,initial_ip_addr,initial_dest,initial_dialplan,initial_context d9be476b-6a9d-4c96-95fb-5d8728bcc08e,inbound,2017-08-29 10:59:35,1503997175,sofia/external/149@dialin,CS_EXECUTE,149,149,dialin,4600,playback,{playBackId=2573}us/announcement.wav,XML,default,L16,8000,128000,PCMA,8000,64000,,1250-0110,,,,ACTIVE,,,,,,,149,149,dialin,4600,XML,public 1 total.

Same issue exists with FreeSWITCH 1.6.19. We are continuously sending api commands to the channel. Could this be a race condition, receiving an api, while the Channel is trying to close ? Would bgapi help ? Why is it not an issue with FreeSWITCH 1.6.8 ? Regards, Tobias

detect_speech via Event Socket not working
by Henning Heedfeld 01 Sep '17

01 Sep '17

Hi, I cannot get the detect_speech app working. I fire the command as following: SendMsg 31ada607-aede-4073-86ff-4dcc318ee839 call-command: execute execute-app-name: detect_speech execute-app-arg: unimrcp:uni2 builtin:speech/transcribe This is the only result I see in fs_cli: 2017-09-01 17:15:26.518812 [DEBUG] switch_ivr.c:623 sofia/internal/1001@tst Command Execute detect_speech(unimrcp:uni2 builtin:speech/transcribe) EXECUTE sofia/internal/1001@tst detect_speech(unimrcp:uni2 builtin:speech/transcribe) When I use the play_and_detect_speech app instead, the MRCP connection is established immediately and everything is working fine. SendMsg 31ada607-aede-4073-86ff-4dcc318ee839 call-command: execute execute-app-name: play_and_detect_speech execute-app-arg: /tmp/beep.wav detect:unimrcp:uni2 builtin:speech/transcribe What am I doing wrong? Thanks for any hints, Henning
