Could someone please explain what the effect the -waste parameter has on starting FreeSwitch? Also, what are the implications of turning off the scoreboard by running with -nosql? What functionality is lost? thanks, -- Guillermo Ruiz Camauer

Delays on VirtualMachines vs baremetal
by Daniel Ivanov 25 Jun '14

25 Jun '14

I am running multiple FS nodes on virtualmachines and sometimes am getting choppy audio and network delays when network conditions are perfect. Do you think it's worth migrating the instances to bare metal and will i notice improvement in call quality?

NORMAL_CIRCUIT_CONGESTION on gsmopen
by Shlomi Agiv 25 Jun '14

25 Jun '14

(moved from a different thread) on occasion, when trying to make a call, we're getting 'NORMAL_CIRCUIT_CONGESTION' and we're not getting any incoming calls. Currently what we do is unload mod_gsmopen, remove and reinsert the usb stick, then load mod_gsmopen. This also doesn't always help since sometimes we can't unload the gsmopen module (it says 'model in use'). in that case we restart freeswitch and reinsert the usb stick. This might not be caused by the gsmopen, since we're controlling the messages coming from the sim, and we might be doing something wrong. Anyone know what the issue is? Thanks, Shlomi

Core parameters questions
by Guillermo Ruiz Camauer 24 Jun '14

24 Jun '14

There are a few Core Parameters in switch.conf that I would like to know when they should be tweaked from their default configuration: max-db-handles: Should there be one handle every N simultaneous calls? What is N? initial-event-threads: Does it hurt or help to bump this up to 2 or 3 on an 8 core machine, even if the WARNING "Create additional event dispatch thread" hasn't come up? db-handle-timeout: What symptoms would indicate that this needs tuning? Should it somwhow be scaled when max-db-handles is changed?Thanks, -- Guillermo

How to configure Freeswitch for SIP over WebSocket behind server-side NAT?
by Bernhard Wendel 24 Jun '14

24 Jun '14

Dear all, I have a FreeSWITCH server that lies behind a NAT on the server side. While usual SIP-Calls (using UDP) are working, I'm facing issues when it comes to the WebSocket Server. While specifying the external IP in the profile definition (<param name="ext-sip-ip" value="$${external_rtp_ip}"/>), on WebSocket the server sends the private instead of the public ip. The reverse proxying is done using nginx. As I didn't found an answer on the web, I hope you can help me! Here is a snippet of the ws communication (FreeSWITCH is answering the INVITE; 172.XX.42.1 is the private gateway and public nginx server; 172.XX.0.3 is the private IP the FreeSWITCH server uses): SIP/2.0 200 OK Via: SIP/2.0/WS ii6c2sdshbua.invalid;branch=z9hG4bK7579777;received=172.XX.42.1;rport=43567 From: <sip:13c0f2b0-b5b8-4822-afe6-38930cddc646@domain.tld>;tag=8a01krubf0 To: <sip:a3352c35-7a6d-4c9e-aeea-1a5f74e90b6f@domain.tld>;tag=p2K9pvtH70Nmm Call-ID: l6ijpvvic6l1ung778sr CSeq: 6213 INVITE Contact: <sip:a3352c35-7a6d-4c9e-aeea-1a5f74e90b6f@PUBLIC.IP:5060;transport=udp> User-Agent: FreeSWITCH-mod_sofia/1.3.4-n20140511T185316Z-1~trusty+1+git~20140509T214701Z~7e0995d069~64bit [...] o=FreeSWITCH 1403358295 1403358296 IN IP4 *172.XX.0.3* s=FreeSWITCH c=IN IP4 *172.XX.0.3* [...] a=ice-pwd:6MXY3JdpOCdmDT9W a=candidate:0823320109 1 udp 659136 *172.XX.0.3* 25176 typ host generation 0 The nginx proxy configuration looks like the following: location /sip { access_log off; proxy_pass http://172.XX.0.3:5066; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # WebSocket support (nginx 1.4) proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_redirect off; } What configuration options do I have to set, so that FreeSWITCH uses the public IP for candiate creation and all other occurences instead of the private one? Or is it easier to adjust nginx configuration to replace the IP? Kind regards Bernhard

Multi-Tenant Versus Multiple FS Instances
by Jerry Richards 24 Jun '14

24 Jun '14

Has anyone considered the Multi-tenant implementation (as described in the FS Wiki) versus having multiple Freeswitch instances running on the same machine (i.e. one instance for each company)? I am wondering if there is a trade-off between these two approaches? Regards, Jerry

mod_xml_curl parse problem and solution
by Colin Martin 24 Jun '14

24 Jun '14

Hi, I was on IRC briefly yesterday asking about a parsing issue I had with mod_xml_curl. Essentially although the XML was correct, the parsing was failing. The person I was discussing it with suggested removing the header (<?xml version="1.0" encoding="UTF-8" standalone="no”?>) which was being generated by the library I was using to generate the XML. This header appears in many examples in books etc and so it had not occurred to me to remove it. Anyway, removing it worked and now mod_xml_curl is working perfectly for my needs, so thanks to the person who suggested it (sorry I can’t remember the IRC nick), and hopefully this’ll turn up in someone else’s Google search if they have a similar problem in the future. Thanks, Colin Martin

Announcing FreeSWITCH Chinese Book and some FreeSWITCH updates from China
by Seven Du 24 Jun '14

24 Jun '14

Hi list, I’m glad to announce that the first Chinese book about FreeSWITCH (FreeSWITCH the Definitive Guide ) is available - http://book.dujinfang.com . During the years, the Chinese Community was growing and we have 1191 members in our local IRC Group - QQ. And we just finished a tiny ClueCon called FreeSWITCH Developers’s Salon where 100+ people joined us last week. We also suscessfully done 2 FreeSWITCH training sessions in Spring and Summer, Shanhai and Beijing respectively. Each has 30+ people attended and they came from everywhere in China mainland, and Taiwan. The FreeSWITCH Developers’s Salon 2014 is non profitable, but we got a few sponsors this year and a little money left so we donated to the FreeSWITCH community. ClueCon is coming and thanks Anthony and his team brought us so great software. I’m not doing Ads but China has biggest market in every aspects so if you are expand your services to China or finding VoIP terminations etc I might have some thoughts or suggestions. Meet at ClueCon. -- Seven Du http://about.me/dujinfang http://www.dujinfang.com http://www.freeswitch.org.cn
