PROTOCOL_WARNING when sending a fax via T.38
by Markus Bönke 18 Sep '15

18 Sep '15

Hello, I want to send a fax between two freeswitches (1.4.20) via T.38. On the SENDER freeswitch, I have Sangoma A104 TDM card and use the following dialplan: <action application="export" data="fax_enable_t38=true"/> <action application="export" data="fax_enable_t38_request=true"/> <action application="export" data="fax_verbose=true"/> <action application="export" data="execute_on_answer=t38_gateway self"/> <action application="bridge" data="sofia/external/${destination_number}@${destination_ip}"/> On the RECEIVER freeswitch I use the this dialplan: <action application="answer" /> <action application="playback" data="silence_stream://2000"/> <action application="set" data="fax_enable_t38_request=false"/> <action application="export" data="fax_enable_t38=true"/> <action application="rxfax" data="/tmp/FAX-${uuid}.tiff"/> When I try to send a fax, on the RECEIVER freeswitch, I can see in the (second) INVITE the T.38 data is present: ... a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxFillBitRemoval a=T38FaxRateManagement:transferredTCF a=T38FaxMaxBuffer:2000 a=T38FaxMaxDatagram:400 a=T38FaxUdpEC:t38UDPRedundancy … On the SENDER side I can see that it tries to start the t38_gateway … 2015-09-17 23:36:51.092799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38 Rx 2: IFP 00 2015-09-17 23:36:51.092799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38 Rx 2: indicator no-signal 2015-09-17 23:36:51.092799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38G Changing - (0) ced -> no-signal 2015-09-17 23:36:51.092799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38G Changing to no-signal 2015-09-17 23:36:51.092799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38G Non-ECM mode 2015-09-17 23:36:51.172799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38 Rx 3: IFP 06 2015-09-17 23:36:51.172799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38 Rx 3: indicator v21-preamble 2015-09-17 23:36:51.172799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38G Changing - (0) no-signal -> v21-preamble 2015-09-17 23:36:51.172799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38G Changing to v21-preamble 2015-09-17 23:36:51.172799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38G Non-ECM mode 2015-09-17 23:36:52.072799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38G HDLC underflow at 4 2015-09-17 23:36:52.172799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38 Rx 4: IFP c0 01 80 00 00 ff 2015-09-17 23:36:52.172799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38 Rx 4: (0) data v21/hdlc-data + 1 byte(s) … But then fails with a protocol error 2015-09-17 23:34:07.652799 [DEBUG] mod_spandsp_fax.c:286 FLOW T.38 Tx 1: indicator v21-preamble 2015-09-17 23:34:07.652799 [ERR] mod_spandsp_fax.c:659 INVALID WRITE: 8:3 2015-09-17 23:34:07.652799 [ERR] mod_spandsp_fax.c:671 TERMINATING T30 STATE … 2015-09-17 23:34:07.652799 [WARNING] mod_spandsp_fax.c:286 PROTOCOL_WARNING T.38 Tx packet handler failure On the RECEIVER side the fax fails with „result (49) The call dropped prematurely“. Can this be because of a wrong configuration (dialplans/mod_spandsp), or is this a bug? Thanks and Regards Markus

Dialplan to listen live calls with mod_xml_curl
by Rutu Patel 18 Sep '15

18 Sep '15

Hi All, I want to enable live call listening with xml_curl module. I have tried by enabling mod_spy,mod_shout and tested telecast webapi. Now I want to integrate it with mod_xml_curl.I am using ESL and followed instructions mentioned at https://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_eavesdrop but no luck. Is there anyway to achieve this? Anyone have suggestions regarding this? -- Thanks, Rutu Patel <http://www.inextrix.com>

Large number of extensions with presence - any performance implications?
by Yehavi Bourvine 18 Sep '15

18 Sep '15

Hello, We currently have over 500 extensions, most of them sharing the same profile which has presence enabled (since some of them need shared lines and BLFs). I am now watching the future of having over 6,000 extensions on that PBX. So' I have a few questions: - Does having all the phones on the same profile can induce performance problems which we won't face if we split them among a few profiles? - Is there a difrerence (mainly database access) between placing all phones that need presence on the same profile vs. splitting them to 3-4 profiles? - About 2/3 of the phones do not really need presence; however, it is more comfortable for me to put them on the same profile. Will the databases access due to presence events might be so high that I should invest the effort to put the single line phones on a different profile without presence? Thanks, __Yehavi:

proxy-refer
by huseyin kalyoncu 17 Sep '15

17 Sep '15

Hello, When i set proxy-refer=true on the sip profile; Attended & blind transfers from uas to Freeswitch show strange debug outputs like this: [DEBUG] sofia.c:8848 sofia/main/nobody@freeswitch_ip receiving invite from proxy_ip:5060 version: 1.4.20 64bit Freeswitch shows transfer target as nobody on all incoming transfers. But when i check with tcpdump, i see all Invite (also Refer) packets have correct from & to fields. Is this normal behaviour or do i have a config problem? 007 calls 009, then 009 calls 002 and makes a attended transfer. All bridging done on Freeswitch. Call is successful but Freeswitch shows empty user for transfer target in the cdr: from to calltime reason "009","002","2015-09-16 16:40:28","PICKED_OFF" "007","009","2015-09-16 16:40:16","NORMAL_CLEARING" "009","","2015-09-16 16:40:38","NORMAL_CLEARING" Freeswitch version 1.4.20 running on debian jessie. Thanks Huseyin

non-blocking music
by Matt Broad 17 Sep '15

17 Sep '15

Hi, I can see that this question has been asked before, but my googling ability has let me down. Is it possible to play some music which does not block? I am trying to put together a javascript service that will play music whilst doing some other tasks. I have tried playfile & uuid_broadcast and both block. Is there another method that I am missing? Or perhaps I am missing something :) Any help would be appreciated. thanks

Automatic transcoding does not seem to occur.
by Michael Nielsen 16 Sep '15

16 Sep '15

I've got a client with OPUS and G.711 codecs enabled and FreeSWITCH with OPUS and G.711 codecs enabled. I've got a SIP gateway connected to FreeSWITCH with only support for G.711. I want to have clients only use OPUS codec - as this seems best for mobile data connections. As of now client <-> FS <-> client use OPUS, but whenever the SIP gateway is involved G.711 is chosen. If I disable G.711 codec on the client side, to force OPUS, I'm not allowed to dial out via my SIP gateway. So transcoding to G.711 does not occur. My fs_cli reports this: Hangup sofia/external/+4413265874 [CS_CONSUME_MEDIA] [SERVICE_NOT_IMPLEMENTED] Again, reenabling G.711 in the client and everything works. I have not set disable-transcoding=true. What to do?

Hi, With FS 1.4 I used the following dial plan to call a python script located under /usr/local/freeswitch/scripts/ <action application="python" data="send-xmpp”/> Is the scripts directory still available somewhere with the FS 1.6 debian package? Thanks! Raphael
