New message from latest STABLE git - Auto-Fixing Broken SLA
by Sean Devoy 11 Mar '14

11 Mar '14

Hi All, I succeeded in refreshing with the latest git from stable this weekend. Many thanks to Brian West. I have a new message on my console and I don't know how worried I should be. It appears that one of my registered extension sent an INVITE which generated the "Auto-Fixing Broken SLA" message 2014-03-11 13:33:59.859112 [WARNING] sofia_reg.c:1532 SIP auth challenge (INVITE) on sofia profile 'external' for [303@<asecret>.com] from ip <irrelevant> 2014-03-11 13:33:59.959109 [WARNING] sofia.c:8585 Auto-Fixing Broken SLA [<sip<my domain>>;appearance-index=1] Is this indicating a possible configuration error in FS or on the device? Is this something I need to fix? Thanks, Sean

Re: [Freeswitch-users] performance

Hi Ali, I am using 1.22 as it's the latest stable for production use. If you use the latest release, 1.4.x I think it is then I have seen a massive performance improvement. However I think my issues are mainly around the timer settings. As I said before I don't really understand enough to know what the impact of changing these settings! I'm continuing to play so will feed back my findings. Cheers Keith

Hi, No i haven't commented out the RTP timeout value as in my test I echo the RTP back from SIPP so this is fine. If anyone can give me some more info on the rtp-timer function and how it works I can decide whether leaving it off is safe. Thanks Keith

How to set FS variable to the value returned by linux command
by Victor Chukalovskiy 10 Mar '14

10 Mar '14

Hello, I run the same config on multiple boxes. Need to tell apart which box CDR is coming from without setting it manually per-box. Is there a way to set a global variable to the output of linux 'hostname -s' command? E.g. instead of: <X-PRE-PROCESS cmd="set" data="sbc_hostname=sbc1"/> <X-PRE-PROCESS cmd="set" data="sbc_hostname=sbc2"/> ..... <X-PRE-PROCESS cmd="set" data="sbc_hostname=sbcN"/> I need something like: <X-PRE-PROCESS cmd="set" data="'hostname -s'"/>\ Thank you, -Victor

Difference between last_bridge_to and signal_bond
by Victor Chukalovskiy 10 Mar '14

10 Mar '14

Hello, Looking at this for the purpose of putting a and b leg CDRs together: http://wiki.freeswitch.org/wiki/CDR#Putting_Together_CDRs I noticed that ${last_bridge_to} and ${signal_bond) are always the same in my use scenario. Is there any real difference between the two and if so which on is better to use? Thank you, -Victor

Matching incoming calls to a gateway
by mbo 10 Mar '14

10 Mar '14

I’ve setup a gateway, he the configuration: sofia status gateway myGateway ================================================================================================= Name myGateway Profile external Scheme Digest Realm <GatewayIP> Username FreeSWITCH Password no From <sip:FreeSWITCH@<GatewayIP>> Contact <sip:gw+COLT@<FreeswitchIP>:5060;transport=udp;gw=myGateway> Exten myexten To sip:FreeSWITCH@<GatewayIP> Proxy sip:<GatewayIP> Context default Expires 3600 Freq 3600 Ping 0 PingFreq 0 PingState 0/0/0 State NOREG Status UP CallsIN 0 CallsOUT 0 FailedCallsIN 0 FailedCallsOUT 0 ================================================================================================= In default context, I’ve setup the following extension: <extension name="myexten"> <condition field="destination_number" expression="^(\d{5,20})$"> <action application="socket" data="192.168.1.20:8029 async full"/> </condition> </extension> If I dial out via this gateway I can see that the outbound calls are counted in CallsOUT or FailedCallsOUT. But When I receive a call, they are not counted in CallsIN or FailedCallsIN, However the context and the extension matches. How are incoming calls ,mapped to a gateway? Thanks Markus
