Using Unix Environment Variables in FreeSWITCH vars
by Oleg Stolyar 21 Aug '13

21 Aug '13

Hi, I have a somewhat unusual question. Can I use Unix variables somehow in vars.xml? I have an environment variable $FOO. I want to define a variable in vars.xml like this <X-PRE-PROCESS cmd="set" data="my_var=value_$FOO"/> Thank you *Oleg*

Validating configuration freeswitch.xml.fsxml
by Grant Bagdasarian 21 Aug '13

21 Aug '13

Hello, I've started to configure FS from scratch by making my own configuration files, based on the files in the vanilla directory. I don't know if this is normal behavior but whenever I start FreeSwitch and check the freeswith.xml.fsxml file, the XML elements in the freeswitch/conf/customsbc/freeswitch.xml and vars.xml are not shown. Only the commentary is shown in this .fsxml file. Is this normal? Also when running the netstat -unlp command, I see freeswitch isn't binding to the address defined in the bind_server_ip variable. Is this because the configuration isn't properly loaded? Htop shows FS is running.

can't load codec

2013-08-20 19:14:58.820110 [WARNING] switch_core_codec.c:699 Codec PROXY Exists but not at the desired implementation. 90000hz 0ms 2013-08-20 19:14:58.820110 [ERR] switch_core_media.c:1837 Can't load codec? Getting this error with following settings: 1. media proxy mode enabled 2. late negotiation enabled 3. <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G722,PCMU,PCMA,GSM,H264"/> Both sip clients are are h264 capable. The same configuration work fine on freeswitch running over ubuntu 12.04 but generates the above log and error on window 7 x64. I found that the freeswitch version I was using on linux was 1.2 and on windows it was 1.5 with git 39ad799 On Linux I checked out same revision and built it again. I could reproduce the issue on linux too. but in the latest revision the problem seems to be fixed. So now I am going to build the the current revision code for windows. Any comment on this or have anybody faced this issue ? Cheers, Pankaj

Patchs Jira and more....
by Ken Rice 21 Aug '13

21 Aug '13

Hey Guys, there seems to be a rash of people uploading patchs to Jira lately that just do not work... So lets hit this one really quick... 1. if you are patching a generated File like the Makefile or configure script make sure you are patching the files they are generated from... ie: configure.in for configure... 2. don¹t try to diff 2 separate trees... git diff > /tmp/my.fancy.patch.txt¹ from the root of your fs source checkout will give you a plain text file of the patch suitable for uploading to jira. 3. Please include all information you have on the jira and what problem/feature the patch addresses. Don¹t just say ³here¹s a patch² and expect someone to look at it without knowing what it is. 4. If a commiter comments on your jira that you need to freshen the patch please do so in a timely fashion or your patch will go back to the bottom of the queue as they will move on to something else... This isnt ignoring your efforts, but developers tend to get distracted easily with new shiny objects so getting back to them quickly helps tremendously. These simple things will help keep the devs from going crazy! Now for you guys that use git on a regular basis, before you blow a gasket, yes this is very basic, and is intended to be so... Yes there are other (and possibly arguable better ways to generate a patch, but this way is the simplest for people not familiar with git) -- Ken http://www.FreeSWITCH.org http://www.ClueCon.com http://www.OSTAG.org irc.freenode.net #freeswitch

ACL Behaviour
by Andrew Cassidy 21 Aug '13

21 Aug '13

Hi all, I've just noticed a slightly unexpected (in my view) behavior when checking ACLs. If you have an empty ACL with default="allow" it will always return false. Of course the workaround is to add a nonsense node into the list such as 0.0.0.0/32 (either allow or deny) then the ACL works as expected. Now, before people shout FILE A JIRA at me, the reason I haven't is because this behavior may be intended to prevent users accidentally leaving their FreeSWITCH installations open. So my question is, is this the intended behaviour? If so, I'll add it to the wiki. Thanks, -- *Andrew Cassidy BSc (Hons) MBCS SSCA* Managing Director *T <info(a)cassidywebservices.co.uk> *03300 100 960 *F<info(a)cassidywebservices.co.uk> *03300 100 961 *E <info(a)cassidywebservices.co.uk> *andrew(a)cassidywebservices.co.uk *W <info(a)cassidywebservices.co.uk> *www.cassidywebservices.co.uk

Matching context based on sip_req_host
by Grant Bagdasarian 21 Aug '13

21 Aug '13

Hello, I want to match a context based on the value of sip_req_host, but the context isn't matched. <extension name="internal_to_external"> <condition field="sip_req_host" expression="^10\.0\.0\.1$"> <action application="set" data="hangup_after_bridge=false"/> <action application="set" data="continue_on_fail=true"/> <action application="bridge" data="sofia/external/${sip_req_uri}"/> </condition> </extension> Debug output: Dialplan: sofia/internal/31765727000(a)192.168.18.6 Regex (FAIL) [internal_to_external] sip_req_host() =~ /^62\.180\.237\.73$/ break=on-false I checked with an online regex validator and it seems that the first and last '/' character is causing it to not match. I'm not a regex expert, so I would appreciate it if someone could help me out with this. Thanks!
