About Call Transfer
by 王聡 08 May '19

08 May '19

Hey all, I’m trying to add a new function to my callcenter server which allow peers transfer their call to other operator. I added the following configure into my dialplan: <action application="bind_meta_app" data="4 b s execute_extension:att_xfer XML features”/> And features.xml showed like: <extension name="att_xfer"> <condition field="destination_number" expression="^att_xfer$"> <action application="read" data="3 6 'tone_stream://%(10000,0,350,440)' digits 30000 #"/> <action application="set" data="origination_cancel_key=#"/> <action application="att_xfer" data="user/AA-${digits}@$${domain}"/> </condition> </extension> This should works when *4 was pressed and att_xfer activated, however when I test this dialplan, freeswitch showed the log as: 2019-05-08 18:31:46.546807 [DEBUG] switch_rtp.c:7789 RTP RECV DTMF *:1280 2019-05-08 18:31:46.546807 [INFO] switch_channel.c:515 RECV DTMF *:1280 2019-05-08 18:31:46.986810 [DEBUG] switch_rtp.c:7789 RTP RECV DTMF 4:1280 2019-05-08 18:31:46.986810 [INFO] switch_channel.c:515 RECV DTMF 4:1280 2019-05-08 18:31:46.986810 [DEBUG] switch_ivr_async.c:4233 sofia/internal/anonymous(a)192.168.121.11 Processing meta digit '4' [execute_extension:att_xfer XML features] 2019-05-08 18:31:47.226816 [DEBUG] switch_ivr.c:625 sofia/internal/anonymous(a)192.168.121.11 Command Execute playback(local_stream://moh/8000) EXECUTE sofia/internal/anonymous(a)192.168.121.11 playback(local_stream://moh/8000) 2019-05-08 18:31:47.226816 [DEBUG] mod_local_stream.c:907 Opening Stream [moh/8000] 8000hz 2019-05-08 18:31:47.226816 [DEBUG] switch_ivr_play_say.c:1497 Codec Activated L16@8000hz 1 channels 20ms 2019-05-08 18:31:47.226816 [DEBUG] switch_ivr.c:625 sofia/internal/BB-000004@192.168.121.3:54129 Command Execute playback(execute_extension:att_xfer XML features) EXECUTE sofia/internal/BB-000004@192.168.121.3:54129 playback(execute_extension:att_xfer XML features) 2019-05-08 18:31:47.226816 [ERR] mod_native_file.c:74 Error opening /usr/local/freeswitch/sounds/en/us/callie/execute_extension:att_xfer XML features.PCMU 2019-05-08 18:31:47.226816 [ERR] mod_sndfile.c:204 Error Opening File [/usr/local/freeswitch/sounds/en/us/callie/execute_extension:att_xfer XML features.wav] [System error : No such file or directory.] 2019-05-08 18:31:47.246814 [DEBUG] switch_ivr_play_say.c:1941 done playing file local_stream://moh/8000 The anonymous is my test phone and BB-000004 is operator.

redirect + swapping of ports
by Vrajendra VT 08 May '19

08 May '19

Hi, I am a novice in Freeswitch. I have a provider sending me calls on 5060 port only. I have 2 FS's. Calls are landing on FS1. From FS1, I need to redirect to FS2 (lets assume all calls to be redirected) With normal config's (I had done few config changes in default and public), I was able to get some logs albeit (Proxy Authentication error). This may be because by default internal calls are authenticated. Thats why I swapped ports 5060 and 5080 of internal and external profiles. But I am getting 480 error Any help is appreciated. Thanks. Thanks.

ESL connection lost to FS
by Neil Patel 07 May '19

07 May '19

Hi all, I have a fresh server running FS 1.8 from package on Debian 9. It runs a python app connecting to FS using ESL that executes this code per call attempt: c = ESLconnection(str(settings.ESL_HOSTNAME), str(settings.ESL_PORT), str(settings.ESL_PASSWORD)) if not c.connected(): abort() dial_command = "originate …" ev = c.api("bgapi", str(dial_command)) c.disconnect() if ev: result = ev.serialize() logger.debug('API result = {}'.format(result)) When we ran 350K call test, 70K calls got to this code and failed the final if condition, meaning ev was None. No CDR generated. This is totally an unexpected error case for us after tens of millions of calls over last 3 years on our other servers. Any idea why this is happening? The only difference I can see is we’ve not seen this issue on FS 1.6 (built from source), so maybe it’s introduced in 1.8 (run from package)? FYI we've built pyESL from source, which is what's recommended here. Any chance there is an incompatibility between pyESL built from source and FS 1.8 installed from package? Thanks, Neil This question reproduced from Slack <https://signalwire-community.slack.com/archives/CDC8H14PN/p1555508784091900> where I didn't get a response

RTP Packet Loss
by 王聡 07 May '19

07 May '19

Hey all, I established a freeswitch server on a cloud server for video chat based on master branch(1.9.0), and got a problem recently. Last week I found the video was lagged in several hours, and log showed: Correcting calculated ptime value from [1660] to [20] to compensate for [82] lost packet(s) I supposed it was a network trouble, but network monitor showed no huge traffic(no more than 100Mbps), but the inbound traffic was larger than outbound, This problem was gone after I executed the VMotion for this cloud server(without storage, network interface not changed). Is there any suggestions for this problem? Regards. C.Wang

Gateways and DNS and TTL
by David Villasmil 06 May '19

06 May '19

Hello all, When creating a new gateway with a FQDN instead of an IP Address, does freeswitch make a DNS Query on every call or is there a cache or does it follow the TTL? I'm on Debian 9, installed FS from freeswitch's repo. Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

by Ramesh Kandasamy 06 May '19

06 May '19

Hi all, I am relatively new to Freeswitch and I am looking for a way to add isfocus parameter in the Contact header of 200 OK (INVITE response) from the freeswitch. I found channel variable sip_contact_params that can be set in dialplan as below, but it doesnt seem to help. Am I missing something or doing something wrong here? <action application="answer"/> *<action application="set" data="sip_contact_params=isfocus"/>* <action application="conference" data="..." Please advise. Thanks Ramesh

Abuse of files.freeswitch.org
by Brian West 06 May '19

06 May '19

FreeSWITCHers, I have found over 2000 IP Addresses that are abusing the files repo, If you happen to be one that has been blocked please email me directly to resolve your access. This isn't about resources, it isn't about us needing mirrors, its blatant abuse. The few that have come forward and resolved their issues had no idea they were doing this, They have various scripts that have gone off the rails and they are investigating and resolving the issue. AKA When Automation Goes Wrong!
