AWS Instance Recommendations
by Colin Morelli 22 Feb '17

22 Feb '17

Hey list, I'll start by saying I have read the warnings and recommendations to *not* run FS on virtualized hardware. For right now, though, it's really the only option for me. I don't anticipate nor will I expect the behavior to be the same as what I would get on physical hosts, but would just like it to be as consistent (and good) as possible given the constraints. My question is - does anyone have particular kernel and instance type recommendations for AWS? I'm getting relatively frequent jitter and what seem like timing-related issues on calls, even in simple device <-> device calls within FS (no external gateway involved). I'm currently running FS in a Debian 8 docker container (with no memory or CPU limits) on a c4.large Ubuntu 16.04 host (kernel 4.4.0-45, default 250hz timer). The particular behavior I'm seeing *feels and sounds* like a few frames of silence, followed up by the audio being sped up slightly for a second or two (almost like it's trying to catch up), happening occasionally throughout calls. Note that this is with one call, and ~5% CPU usage on the host. Thus I'm pointing a finger most likely at kernel timer resolution. Running time_test 100 on FS returns an average of 200, which seems pretty bad. I've heard people have better success with the Amazon Linux AMIs for their packaged kernels. Is this true? Would recompiling the kernel with a 1000hz timer help a lot here? If you're having success on AWS, would be great to know what AMI you're based off of, what kernel version (and timer), and instance size. Thanks in advance. Best, Colin

Conditional route-advance?
by Jean-Michel Hiver 22 Feb '17

22 Feb '17

Hello Freeswitch-users, In Freeswitch dialplan, you can route-hunt by stacking bridge commands like so: <extension name="internal"> <condition field="destination_number" expression="^1111"> <action application="set" data="hangup_after_bridge=true"/> <action application="bridge" data="sofia/local_profile/1111@@" /> <action application="bridge" data="sofia/local_profile/1111(a)example2.company.com" /> </condition> </extension> My question is - is it possible to have more fine grain control about when to route-advance? For example, it might be OK to route advance when example1.company.com is not reachable or returns a 5XX response code or doesn't return a 183 Session progress or 200, but it may not be OK to route advance on a 4XX for instance... Any ideas on how to have finer control? I haven't found anything relevant in the docs, but if iI've missed something, pointers to the relevant doc would be highly appreciated. All the best JM

Media Intercept
by hide name 22 Feb '17

22 Feb '17

Hello, I am trying to build Media analysis software and need help to figure out how to tag media packets and send it to another process running on different box. 1. Call comes in, dialplan answers channel and I have inbound event socket module to get call details. 2. If this call needs media analysis then I want to send all RTP packets received on channel to a process (UDP socket) running on same/different machine. I only want to send media packets without SIP signaling. If possible tag/encapsulate media packets with uuid or other identification. 3. If inbound channel receive SRTP media then is it possible to send RTP to media analysis process? Thanks in advance. Regards, Ashutosh

Javascript Event Consumer -- How to run at startup?
by Nicholas Blasgen 21 Feb '17

21 Feb '17

I've written a simple Event Consumer which I ported from LUA. When I run it via the CLI, it works great. Now... How do I get the Javascript Event Consumer to run at startup? I would have expected this to be in the documentation, but not yet. There's documentation on it being used as an Event Consumer at https://freeswitch.org/confluence/display/FREESWITCH/JavaScript+Event+Handl… which is great (especially for people like me who already are familiar with event consumers), but just nothing that covers startup scripts. https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/conf/testi… -- example from Lua's config file. There's a "startup-script" variable in the <settings> section https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/conf/insid… -- v8 config, no startup-scripts. There is a very new "hooks" implementation which is interesting, but not ideal when execution time is important (or at least I'd need to performance test it). (copying Andrey Volk on this as he committed the recent hook modifications).

xml_curl and purpose=gateways
by Gregor Nanger 21 Feb '17

21 Feb '17

Does anyone have example what to return in xml_curl request for purpose=gateways for profile. I want to feed gateways definition in external profile from database. Is there such solution to return only gateways or do I need to feed entire sofia.conf if I want to have gateways stored in db? Best regards, Gregor
