Preferred Intel QPI Bandwidth Priority Setting for FreeSWITCH
by Shaun Stokes 17 Oct '16

17 Oct '16

We're looking at deploying FreeSWITCH 1.6 with SIP, Conferencing, Video and WebRTC connected to PostgreSQL for 1000-2000 endpoints using dialplans (stored in memcache) of upto roughly 100 lines. The hardware we've spec'd includes 32GB RAM, 2x Intel X5650 CPUs and 6x 73GB 15.2K SAS HDs in RAID 5 volume (for increased I/O and throughput) on PERC H700 controller. My question is, what would the preferred setting be for Intel QPI Bandwidth Priority, the options are either 'Compute' (default) or 'I/O' (optimized for I/O intensive workloads)? This is what we've found on the suppliers website: The Intel QPI Bandwidth priority has two settings, compute and I/O. It is set to "compute" by default. This option determines the number and priority of requests on the QPI bus. Recall that the QPI connects the processor sockets as well as the IOH. The "compute" setting favors computational traffic while the "I/O" setting is optimized for IO intensive workloads. The last thing we want is an I/O bottlenecks but after researching this on Intel's website I believe the above 'I/O' setting is specifically aimed at prioritizing traffic between the memory controller (RAM) and CPU, while 'Compute' prioritizes computational traffic. Does anyone know what the preference should be FreeSWITCH in this scenario?

FreeSWITCH on Docker
by Ehsan Minachi 16 Oct '16

16 Oct '16

Hello all, We’ve containerized our infrastructure. The only piece left is FreeSWITCH which we’re hesitant. Has anyone run FreeSWITCH under high load in a container? Would love to hear if there are any downsides to running FreeSWITCH in a container. Thank you, - Ehsan

Weekend Maintenance For FreeSWITCH.org
by Ken Rice 14 Oct '16

14 Oct '16

Hey Guys, Major parts of the website infrastructure that makes up https://FreeSWITCH.org will be offline starting late Friday Night (Oct 14th) and will remain offline until sometime on Monday (Oct 17th) This maint window is to allow us to do some much needed software upgrades and to realign some services onto different hardware. For additional information as this maint window progresses please follow us on Twitter @FreeSWITCH We are currently looking to replace some aging infrastructure and this realignment of service will help, but it does not address the underlying issue in that we seriously need to replace several old servers as they just aren't strong enough to keep up with the ever growing loads. You can assist the FreeSWITCH Team in making the hardware upgrades possible by hitting the Donate button on FreeSWITCH.org or via paypal to paypal(a)freeswitch.org <mailto:paypal@freeswitch.org> Tag in your donation that this is to assist in hardware upgrades. Thanks and have a good weekend. Ken Rice FreeSWITCH.org

Changing sound file suffixes

Is possible change sound file suffixes on FS? I would like to share files that I already use in Asterisk with my FS, like .alaw, instead of .PCMA. Regards, Valter

Hello, Two SIP profiles: External 83.хх Internal 10.23.154.0/24 Via external we are receiving/send calls from/to 172.17.2.0/29 For some reason if we call outside FS sends unmodified addresses in SDP.

Re: [Freeswitch-users] Inbound or Outbound Socket connection?

Ok David. There are too things here. I have the dialplan from one side and I have the esl socket from the other side. In the dialplan I should call the esl connection somehow to work on that specefic call in progress. Right? So how can I make this link without an instruction in the dialplan? Does this make sence?

Few things I forgot to ask, the scale-ability I was referring to as horizontal scale and thanks for your input on that. For point#2, mod_curl you mentioned for realtime, will it sustain more than 500-1K CPS and will it stress out the httpd/apache service? For point#3, you mean to say Freeswitch doesn't use system files for media like Asterisk does? For point#4, multi-threading; I forgot to mentioned whether Freeswitch supports multi-processing? As Asterisk, it uses/runs on single process whereas OpenSIPs/Kamilio, we can set multiple child processes.

Inbound or Outbound Socket connection?
by Anis Bedhiafi 13 Oct '16

13 Oct '16

Hi Guys, I guess I have a little confusion here between inbound esl and outbound esl. *My Goal:* What I am trying to do is detect if the call is being transferred and notify the caller about it. *My Scenario:* 1- I have an application based on SIP.js client that makes outbound calls via a registered SIP trunk on my Freeswitch box. I upload a list of phone numbers to call and hit Launch button. 2- Some calls can be transferred by the callee endpoint. I want to detect this fact. 3- According to my research, I can do this using Event Socket library. 4- To detect if there is a transfer, I can control the channel variable RDNIS or TRANSFER_TIME. If there is a transfer these variables are not empty. 5- Once I detect there is a transfer I want to send a NOTIFY packet to the client. *My confusion is the following:* I don't know whether to use an Outbound socket connection or an Inbound Connection. I tried to do this with outbound connection as follows: <condition field="destination_number" expression="^1703$"> <action application="set" data="socket_resume=true"/> <action application="socket" data="127.0.0.1:8084 async"/> <action application="bridge" data="sofia/gateway/mygateway/$1"/> </condition> I have a perl server listening on port 8084/tcp. In this perl script I subscribe for CHANNEL_ANSWER Events and I filter by the call uuid. The problem is when I call the socket connection, the bridge application never executes. How am I supposed to listen for a specific event and make a bridge call? Is what I am doing wrong. Please correct me. Thank you for your support. Kind regards.
