disable video from being automatically added to sdp
by Jimmy Simpson 03 Nov '21

03 Nov '21

I can not seem to disable and stop Freeswitch from adding the m=video to the SDP: m=video 17076 RTP/AVP 104 105 Is there a channel variable I can set to disable all Video. The extra m=video keeps getting added. I only need audio only. This takes up an extra 3 ports that I do not want to take up. --------- in INVITE - From: udp:1.1.1.1:5060 To: udp:2.2.2.2:5060 ------ where 1.1.1.1 is the freeswitch, and 2.2.2.2 is the proxy INVITE sip:107@testsystem.example-domain.com SIP/2.0 Via: SIP/2.0/UDP 1.1.1.1;rport;branch=z9hG4bKX2j1QgS2cepaK Route: <sip:testsystem.example-domain.com:5060> Max-Forwards: 67 From: "test10first test10last" <sip:106@testsystem.example-domain.com >;tag=yDttpta215tXc To: <sip:107@testsystem.example-domain.com> Call-ID: 6bb53aa6-b0aa-123a-8c82-0050568c1d26 CSeq: 43054544 INVITE Contact: <sip:mod_sofia@1.1.1.1:5060> User-Agent: Freeswitch Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Supported: timer, path, replaces Allow-Events: talk, hold, conference, refer Content-Type: application/sdp Content-Disposition: session Content-Length: 991 X-Type: audio X-FS-Support: update_display,send_info Remote-Party-ID: "test10first test10last" < sip:106@testsystem.example-domain.com>;party=calling;screen=yes;privacy=off v=0 o=Cisco9 1635189532 1635189533 IN IP4 1.1.1.1 s=Cisco9 c=IN IP4 1.1.1.1 t=0 0 m=audio 27140 RTP/AVP 102 18 103 9 0 8 106 101 a=rtpmap:102 opus/48000/2 a=fmtp:102 useinbandfec=1; maxaveragebitrate=14000; maxplaybackrate=8000; sprop-maxcapturerate=8000; ptime=20; minptime=10; maxptime=40 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:103 opus/48000/2 a=fmtp:103 useinbandfec=1; maxaveragebitrate=14000; maxplaybackrate=8000; sprop-maxcapturerate=8000; ptime=20; minptime=10; maxptime=120 a=rtpmap:9 G722/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:106 telephone-event/48000 a=fmtp:106 0-16 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 m=video 17076 RTP/AVP 104 105 b=AS:3072 a=rtpmap:104 VP9/90000 a=rtpmap:105 VP8/90000 a=inactive a=rtcp-fb:104 ccm fir a=rtcp-fb:104 ccm tmmbr a=rtcp-fb:104 nack a=rtcp-fb:104 nack pli a=rtcp-fb:105 ccm fir a=rtcp-fb:105 ccm tmmbr a=rtcp-fb:105 nack a=rtcp-fb:105 nack pli

Re: [Freeswitch-users] Codec problem, Freeswitch does not regard absolute_codec_string?
by Rahman Duran 01 Nov '21

01 Nov '21

Hi, I am struggling tuning Freeswitch for late codec negotiation. Here is local profile settings: <param name="inbound-late-negotiation" value="true"/> <param name="inbound-codec-prefs" value="G722,PCMA"/> <param name="outbound-codec-prefs" value="G722,PCMA"/> <param name="inbound-codec-negotiation" value="greedy"/> As you see I enabled late-negotiation and set codecs prefs to allow G722 and PCMA. My goal is to use G722 if both sides support it and fall back to PCMA if G722 is not an option for A leg or B leg. Here is the local dial plan config where I bridge calls: <extension name="local_accounts_freeswitch"> <condition regex="all"> <regex field="destination_number" expression="^[0-9]{4}$"/> <regex field="${local_user_exists}" expression="^true$|^TRUE$|^True$"/> <regex field="${santral_kontrol}" expression="^freeswitch$"/> <action application="set" inline="true" data="call_pickup_group=${user_data(${destination_number}@${domain_name} var call_pickup_group)}"/> <action application="hash" data="insert/${domain_name}-last_dial/${caller_id_number}/${destination_number}"/> <action application="hash" data="insert/${domain_name}-group_pickup_last_uuid/${call_pickup_group}/${uuid}"/> <action application="hash" data="insert/${domain_name}-pickup_last_uuid/${destination_number}/${uuid}"/> <action application="log" data="ep_codec_string -- ${ep_codec_string}" /> <action application="set" data="inherit_codec=true"/> <action application="export" data="nolocal:absolute_codec_string='${ep_codec_string}'"/> <action application="set_profile_var" data="callee_id_name=${user_data(${destination_number}@${domain_name} var effective_caller_id_name)}"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="continue_on_fail=true"/> <action application="set" data="call_timeout=30"/> <action application="set" data="execute_on_answer=sched_hangup +21600 alloted_timeout" /> <action application="bridge" data="{origination_callee_id_name=${user_data(${destination_number}@${domain_name} var effective_caller_id_name)}}user/${destination_number}@${domain_name}"/> <action application="execute_extension" data="hata-${originate_disposition} XML hata_anonslari"/> </condition> </extension> So I export absolute_codec_string to B leg using ep_codec_string. When I test a call from 2730->2110, the call fails with "incompetible_destination". Call logs here: https://pastebin.freeswitch.org/view/b2978e79 The 2730 is a Cisco phone with "G722,PCMU,PCMA,G729,L16,iLBC" codec support. The 2110 is a Samsung phone that only supports "PCMA,PCMU,G729" codecs. As you see cisco invites with all codecs it supports and freeswitch sets absolute_codec_string with "G722,PCMA" as expected from the config. But as you see in the call logs Freeswitch only sends "G722" in SDP to Samsung phone so Samsung rejects the call. Why does Freeswitch only send G722? How can I fix this? What am I doing wrong? P.S. using debian packages: FreeSWITCH Version 1.10.6-release-18-1ff9d0a60e~64bit (-release-18-1ff9d0a60e 64bit) Regards, Rahman Duran

REGISTER with Telekom SIP Trunk
by Schäffner, Johannes 30 Oct '21

30 Oct '21

Hello, I am trying to register with a Deutsche Telekom SIP Trunk. The Deutsche Telekom technical documentation states that the client must set the following SIP header fields: For an initial REGISTER without Authentication Challenge the SIP Header fields - Security-Client: sdes-srtp;mediasec - Proxy Request: mediasec - Requirement: mediasec shall be included. The platform replies with SIP 401 Unauthorised and contains the SIP header fields - Security server: msrp-tls;mediasec - Security server: sdes-srtp;mediasec - Security server: dtls-srtp;mediasec with indication of the possible encryption methods. For the following REGISTER with Authentication Challenge, in addition to the originally included SIP header fields Security-Client, Proxy-Require, Require the SIP header fields - Security Check: msrp-tls;mediasec - Security check: sdes-srtp;mediasec - Security check: dtls-srtp;mediasec shall also be included. According to RFC3261, the Security-Verify header fields can also be combined as a single header field. I have seen, that the Sofia-Stack has implemented these Fields. But I have not found a way to set these header fields in the REGISTER message. (For the INVITE messages I'm using the set action sip_h_*; not sure if this is correct. There I have the Problem, that I'm not able to set the SDP Attribute a=3ge2ae:requested) Regards, Johannes

Bridging a channel via Push Notifcation
by Aditya Uppuluri 29 Oct '21

29 Oct '21

Hello All, Thank you so much for the amazing software. I am new to freeswitch and trying understand how to do the following use case (mobiles): 1. Call is received from LinPhone to User-B 2. Freeswitch (esl code) checks if User-B is a registered user or not 3. If a registered user, forward the call 4. If not a registered user, then send a push notification to the user-B's mobile. 5. Freeswitch parks the call from LinPhone user 6. User-B's mobile gets push notification and get's a call screen 7. User-B accepts the call (Actually, he will send an INVITE with the data received in the payload) 8. Freeswitch receives the invite and should bridge the Linphone user with User-B I am able to perform all the operations except the last one (Bridging the call). If I try to use `uuid_bridge`, it says at least one call must be answered. (*Neither channel is answered, cannot bridge them*. ) May I know how to bridge these two legs in freeswitch? FYI: I have the following park-only dialplan and controlling everything from esl <extension name="fspark"> <condition field="destination_number" expression="^(.*)$"> <action application="set" data="bypass_media=true"/> <action application="set" data="bypass_media_after_bridge=true"/> <action application="park"/> </condition> </extension> Thanks in advance Regards, Aditya

Expert help needed debuging sip registration [logs included]
by Miguel Andrade 29 Oct '21

29 Oct '21

Some how I'm able to register sip phones and softphones but not as a freeswitch gateway. I've tried several combinations to no avail. My provider instructions are: · Endereço Registar (Host): sip.sapo.pt · Endereço Proxy (Outbound Proxy): proxy.sip.sapo.pt · Porta Proxy: 5070 · Username: +3513020xxxxx (*) · Password: [de 6 a 8 carateres] · Transporte Rede (Network Settings): UDP · SIP URL: +3513020xxxxx (*) I've entered this as username: +351xxx, password: xxx, proxy: proxy.sip.sapo.pt:5070 , from domain: sip.sapo.pt Doesn't work. I went to advanced and set transport to udp and outbound proxy as proxy.sip.sapo.pt:5070 didn't work wither. Tried all combinations I could but also no cigar. Can anyone help me debug this?

Changing device on one leg improves the audio recorded from another leg?
by David P 29 Oct '21

29 Oct '21

We had this bizarre experience today: A user on this device... Dell Latitude 5580 i7-7600U CPU Windows 10 Education OS 19042.685 ...made verto calls in which he heard clicks and pops every few 100ms from our virtual agent on another leg, and those audio defects also appear in the mp4 recording. When he then switched to this device *on the same desk* using the same network... Dell Latitude 5590 i5-8350U CPU Windows 10 Education OS 17763.1821 ...there were no audio defects. Playing audio from other sources on the problematic device revealed no problems with its speaker. At least one of the failed calls used srflx candidates, not any relaying. How could changing the device on leg A affect the audio recording that apparently comes from leg B? If it's relevant: - We use "jitterbuffer_msec=5p:100p" - xml_cdr logs for both legs show seemingly high values for some aspects like these... - <skip_packet_count>187</skip_packet_count> <jitter_packet_count>1620</jitter_packet_count>

Trying to get short hostname
by Antony Stone 28 Oct '21

28 Oct '21

Hi. I'm using FreeSwitch 1.10.7 as a client registering to other PBXs as well as a SIP server itself. I am setting the user-agent string in the SIP profile, such as: <param name="user-agent-string" value="FS $${CFGver} $${hostname}"/> The variable $${CFGver}} is a version string I'm definiing in vars.xml This is working, but it gives me the FQDN of the machine as $${hostname}} and I really only want the machine name without the domain. I've found https://freeswitch.org/confluence/display/FREESWITCH/Regular+Expression and https://freeswitch.org/confluence/display/FREESWITCH/mod_dptools:+regex and I've tried to use them to cut the domain off the value of $${hostname} but with no success: In vars.xml: <X-PRE-PROCESS cmd="set" data="shorthostname=${regex($${hostname}|([^\.]*).*| %1)}"/> This results in the variable shorthostname being assigned the value: %{regex(abcd.efgh.tld|([^\.]*).*|%1)} where abcd.efgh.tld is the server's FQDN. Instead of doing that in vars.xml and creating the variable shorthostname, I tried putting the regex into the SIP profile: <param name="user-agent-string" value="FS $${CFGver} ${regex($${hostname}| ([^\.]*).*|%1)}"/> This ends up with precisely the same result. The ${regex(....)} function simply isn't being executed. Given that the machine's hostname is also available from the system command "hostname -s" I decided to try that instead: In vars.xml: <X-PRE-PROCESS cmd="set" data="shorthostname=${system(hostname -s)}"/> Or in the SIP profile definition: <param name="user-agent-string" value="FS $${CFGver} ${system(hostname -s)}"/> These both produce the output: FS 0.65 ${system(hostname -s)} In other words, the ${system(....)} command isn't working any more than ${regex(....)} did. What am I doing wrong please? How can I get the machine's short hostname into a user-agent string for registration to a server? Thanks, Antony. -- Perfection in design is achieved not when there is nothing left to add, but rather when there is nothing left to take away. - Antoine de Saint-Exupery Please reply to the list; please *don't* CC me.

Postgress BDR insert failed for "complete" table
by Abdirahman Osman 28 Oct '21

28 Oct '21

Hello, I am using postgres with BDR bidirectional replication which requires primary keys for the freeswitch tables. So far so good , except freeswitch is complaining about one table here is the error 2021-10-26 23:40:47.772796 95.47% [DEBUG] mod_pgsql.c:784 Query (insert into complete values (0,'hash_remote', 'list', '', '', '', '', '', '', '', '', 'dagobah-api-gw-1-2')) returned PGRES_FATAL_ERROR 2021-10-26 23:40:47.772796 95.47% [ERR] mod_pgsql.c:551 Error executing query: ERROR: column "complete_uuid" is of type uuid but expression is of type integer LINE 1: insert into complete values (0,'hash_remote', 'list', '', ''... What I noticed is that freeswitch is doing an INSERT INTO command with no column names specified. I checked the source code and found this to be the only case for the "complete" table whereas the other tables when INSERT INTO is used column names are specified. Here is the structure of my complete table with the new column complete_uuid as primary key. CREATE TABLE :myschema.complete ( complete_uuid uuid DEFAULT public.gen_random_uuid() PRIMARY KEY, sticky INTEGER, a1 VARCHAR(128), a2 VARCHAR(128), a3 VARCHAR(128), a4 VARCHAR(128), a5 VARCHAR(128), a6 VARCHAR(128), a7 VARCHAR(128), a8 VARCHAR(128), a9 VARCHAR(128), a10 VARCHAR(128), hostname VARCHAR(256) ); Any suggestions? Thanks Abdirahman A. Osman

Issue with mod_event_multicast in 1.10.7
by Koldo Aingeru 28 Oct '21

28 Oct '21

Hi, I just updated a test server from FS 1.10.6 to 1.10.7 on Debian 10 (apt update/upgrade from the official repo) and without changing anything on my config I got a buffer overflow when running "/usr/bin/freeswitch -u freeswitch -g freeswitch -c -nonat ": *** buffer overflow detected ***: /usr/bin/freeswitch terminated Aborted I tried the original modules.xml that comes with the package and it starts up without problems. Doing a bit of trial & error with my modules.conf.xml I noticed that the problema is with the mod_event_multicast module. Loading it from modules.conf.xml or by doing “load mod_event_multicast” result in a crash. This is the current module: # sha1sum /usr/lib/freeswitch/mod/mod_event_multicast.so 4daee6fa8ae8ed59c5ebc32393cb7357fead8198 /usr/lib/freeswitch/mod/mod_event_multicast.so Overwriting the module with the 1.10.6 one seems to work: freeswitch(a)pbx.mydomain <mailto:freeswitch@pbx.mydomain>.com> load mod_event_multicast +OK Reloading XML +OK 2021-10-28 14:21:23.038592 96.17% [CONSOLE] switch_loadable_module.c:1768 Successfully Loaded [mod_event_multicast] 2021-10-28 14:21:23.038592 96.17% [NOTICE] switch_loadable_module.c:389 Adding API Function 'multicast_peers' but even with the module loaded the events aren't being sent to my other server, my event_multicast_conf.xml is this: <configuration name="event_multicast.conf" description="Multicast Event"> <settings> <param name="address" value="225.1.1.1"/> <param name="port" value="4242"/> <param name="bindings" value="CUSTOM sofia::register"/> <param name="ttl" value="1"/>     <param name="psk" value=“pbx.mydomain.com"/> </settings> </configuration> I don’t see any multicast traffic being sent from this server nor the " Propagating registration for….” message. Any idea what can be happening? Thanks! ======================================== Koldo Aingeru Marcos Fdez.
