Floating IPs and fs_cli
by Zach Rothy 14 Dec '16

14 Dec '16

Good Evening, I recently set up a floating IP on freeswitch as I have 2 servers that will be running as active and standby in case one goes down. I have the sip profiles for internal and external ipv4 as well as verto communicator's conf file set to bind to this floating IP. I also added the required thing to sysctl as listed on the high availability page so that it won't have problems binding to that IP if it wasn't there for some reason. After I set this all up I noticed I could no longer connect to the CLI with fs_cli. Is there some special arguments that have to be passed or used to access the CLI when using a floating IP address? Some notes of my set up: Though I mention high availability, I only referenced it for any settings that may be needed for freeswitch to bind properly to a floating IP and do not actually plan on doing anything else besides this floating IP. Right before I set this up my coworker had shut IPv6 off on the server as it was not needed. I noticed this as the IPv6 profiles couldn't bind anymore, and I had temporarily removed the sip profiles to remove errors in case that was a problem. Thanks in advance, Zach R

Dialplan not executed when INVITE has no SDP (3pcc)
by Dave Horton 14 Dec '16

14 Dec '16

I notice that when I set: <param name="enable-3pcc" value="true”/> and then send an INVITE to Freeswitch with no SDP, Freeswitch responds with 200 OK and an SDP offering all available codecs. That is good, but it also appears that it does not evaluate the dialplan at all - simply sends out the 200 OK. Is this by design? My intent was to send an INVITE with no SDP, execute answer through my event socket program and thereafter be able to issue commands. It seems like this is not possible? Or am I doing something wrong? Dave

Screen/document sharing with WebRTC/Verto API?
by Fred Pettersson 14 Dec '16

14 Dec '16

Can someone point me to an example of how-to do screen/document sharing and Verto API? Maybe a stupid question: since FreeSWITCH is a b2bua - does documents go (flow) through FreeSWITCH when screen/document sharing with WebRTC/Verto? Regards, Fred

Generating a INVITE with multipart content
by Marcel Haldemann 14 Dec '16

14 Dec '16

Hi, I need to generate a "content-type: Multipart" Body and add two additional content parts to an INVITE on the B-LEG (bridge). Is this currently supported ? I found there is the variable sip_multipart. If I set something in this var the outbound INVITE is MULTIPART. How can I add two additional parts to the body ? Tried some wired stuff such as: <condition field="${Username}" expression="^([5])$"> <action application="export"><![CDATA[sip_multipart[0]=application/pidf+xml]]></action> <action application="export"><![CDATA[sip_multipart[1]=test]]></action> <action application="export"><![CDATA[sip_mp_application/pidf+xml=testdata]]></action> <action application="info"></action> </condition> How to add this body parts ?

freeswitch fetching old records from sqlite
by Aqs Younas 14 Dec '16

14 Dec '16

Hi, We are using SQLite(separate database than core) with javascript and have observed a bizarre issue. Freeswitch query (Select) shows old records whereas data was changed a few minutes before. Sometimes updated data reflects back in FreeSWITCH after several minutes. Whereas in PHPadmin I see updated data for the query. I have asked the question on IRC where they advised me to change the database. Is there any workaround for this? Does freeswich caches data from sqlite? Sorry for asking again, we have a system in production doing some sqlite select queries, changing database would be the last option. Best, Aqs Younas

Lua DTMF Test
by Andrew Cassidy 14 Dec '16

14 Dec '16

Hi guys, Trying to build a DTMF test using flite TTS. So far I have this: session:setVariable("tts_engine", "flite") session:setVariable("tts_voice", "stm") digits = session:playAndGetDigits(2, 30, 3, 5000, "#", "say:Please enter some digits, followed by the hash key.", "say:Sorry, I didn't catch that. Please try again.", "\\d+") session:execute("speak", "flite|stm|" .. digits) I keep getting the following error and can't work out why: 2016-12-13 19:16:10.377932 [ERR] mod_lua.cpp:203 /usr/share/freeswitch/scripts/dtmf_test.lua:9: attempt to concatenate field '?' (a nil value) stack traceback: /usr/share/freeswitch/scripts/dtmf_test.lua:2: in main chunk It's mostly something stupid I'm doing, out of everything I'm good at lua isn't one of them! Does anyone have any ideas what I'm doing wrong?

Hello, During some call peaks, FS replies with 503 Maximum Calls and produces the following log: /var/log/freeswitch/freeswitch.log.2016-12-12-10-20-33.1:2016-12-12 10:08:54.964919 [CRIT] switch_core_session.c:2270 Over Session Limit! 973 /var/log/freeswitch/freeswitch.log.2016-12-12-10-20-33.1:2016-12-12 10:08:54.964919 [CRIT] mod_sofia.c:4406 Error Creating Sessi I dig into the configuration to change many settings related to this error.

Windows Azure and Freeswitch Compatibility / Issue
by Duke, Jeremy 13 Dec '16

13 Dec '16

Hello, I'm fairly new to FS and hopeful that someone can help me with this problem. We are trying to do a basic POC and make sure FS can work on Azure. Setup: Azure (MS Cloud) Windows 2008 R2 FS Installed X Lite Softphone Installed on Server Current State / Issue: I'm able to use the softphone to register, make extension calls, etc. from the server itself using local IP address (10.0.0.4). However, when I use the servers public IP address I can't register the softphone. I'm sure I'll have NAT issues to deal once I get past the phone registration. However, given I don't see registration attempts I'm thinking I have configuration issue within FS (ACL, ...). Things I've Done: - I've opened up UDP and TCP port ranges 5000-9000 for both inbound and outbound in Azure Portal. - I opened ticket with MS and we used network trace to verify that UDP traffic was mapping into server from outside and getting through the Azure firewall (network security group). I had initially suspected this as culprit, but MS is telling me they now allow UDP traffic. - Ran FS_CLI in debug to look at registry events and I get nothing on the failed registry attempts. - Looked at FS log. I don't see any clues. Thoughts on issue? Anyone else had experiences with Azure and FS.
