Re- FreeSWITCH CDRs ${billsec} not correct when using Lua scripts and running a hangup handler with any delays inside it
by Andrew Keil 27 Feb '15

27 Feb '15

To FreeSWITCH users, I am currently experimenting with Lua scripts on FreeSWITCH (latest build) and found an interesting issue with FreeSWITCH default CDRs (inside log/cdr-csv/1000.csv). See below for my simple Lua script called from a diaplan as follows: <include>  <extension name="ivr_demo"> <condition field="destination_number" expression="^(9101)$"> <action application="lua" data="myservice.lua"/> </condition> </extension> </include> What I noticed is that placing a call into FreeSWITCH via a SIP phone (calling 9101) and landing on myservice.lua everything processes as expected. If I hangup after 3 seconds then I should expect the CDR to show ${billsec} = 3. However this is not the case since both ${duration} and ${billsec} are actually set once the Lua script completes (not based on HANGUP). So inside 1000.csv I see duration and billsec both having 8 seconds. You will see below that inside my hangup handler (function myHangupHook(s, status, arg)) I fire an event and wait up to 5000ms for an event to be returned (currently I am not returning an event so the 5000ms will take place). This explains the extra 5 seconds after the 3 seconds of the call. My question is since FreeSWITCH knows that the HANGUP has taken place why is the ${billsec} not correct (ie. should be 3 seconds)? I tried adding "session:hangup()" as the first line inside my hangup handler (function myHangupHook(s, status, arg)) and this made no difference. Is there a solution to this issue? Perhaps there is a different CDR variable that will contain the correct duration based on when HANGUP was actually received. Thanks in advance for any assistance with this. Regards, Andrew Keil Simple Lua Script: -- myservice.lua -- To test a simple service function MainService() freeswitch.consoleLog("INFO", "MAIN SERVICE SECTION\n") -- answer the call freeswitch.consoleLog("INFO", "ANSWER CALLER\n") session:answer(); -- sleep a second freeswitch.consoleLog("INFO", "Sleep for 1000ms\n") session:sleep(1000); freeswitch.consoleLog("INFO", "Playing 12345\n") session:say("12345", "en", "number", "pronounced"); freeswitch.consoleLog("INFO", "Finished playing 12345\n") if (session:ready()) then -- hangup freeswitch.consoleLog("INFO", "HANGUP\n") session:hangup() end end -------------------------------------------------------------------------------------------- -- Functions section ... function myHangupHook(s, status, arg) freeswitch.consoleLog("INFO", "myHangupHook: " .. status ..

How to measure QOS?
by Andrew V 27 Feb '15

27 Feb '15

How do you measure quality of service across all calls? What are ways to avoid bad quality of service? Say the call volume is in your control. Is it as easy as not letting the call volume get out of control? The attached is a hypothesis of the relationship between QOS and the number of concurrent calls. Does it work that way? What other factors need to be taken into account? [image: Inline image 1]

server to NAT'd server gateways
by Robert Oldham 26 Feb '15

26 Feb '15

I have two FreeSWITCH servers that I need to gateway calls between. Sip_A is on a public network with a static IP address. Sip_B is on a private network that is NAT'd. I am trying to pass calls from devices connected to Sip_B, through Sip_A and on to another server. I am also trying to pass calls from Sip_A into Sip_B. I don't have access to the firewall at the location of Sip_B so I am not able to forward standard ports into Sip_B. I am fairly new to FreeSWITCH, so I'm not certain how to solve this problem well. Many of the documents I have read online recommend using ACLs and port forwards for this. However, the private network does not have a static IP address that I can give access to and, as mentioned, I cannot make port forwards. Instead, I have created an extension on Sip_A and a gateway on Sip_B that registers using the extension on Sip_A. That works fine for passing calls from Sip_B through Sip_A and on. Sip_B has been maintaining a registered connection to Sip_A through the NAT'd connection for several days now without trouble. Not knowing a better solution, I have been searching for a gateway configuration on Sip_A that would allow it to route calls back over the registered extension from Sip_B. I have not found a way to accomplish it yet. As an alternative, I have also tried without success to create a passive gateway on Sip_A that the gateway on Sip_B could register with. Any help is appreciated! Thanks, Robert

updated xml file not seen by freeswitch
by dragoncloud 26 Feb '15

26 Feb '15

Hi, Don't know how I did this, but, I put in the wrong IP address in my xml file for freeswitch. I've edited and corrected it, but, freeswitch is still showing the incorrect one and it's in NOREG status. Can anyone tell me how to get freeswicth to see the new xml file? I've done "sofia profile external rescan reloadxml" but that doesn't do it. I've even tried "sofia profile (profile name) killgw (gateway name)" to get rid of the incorrect one, but, to no avail. Any help would be appreciated! -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/updated-xml-file-not-seen-by-… Sent from the freeswitch-users mailing list archive at Nabble.com.

?Hi, I have read in a number of places that you can have rtcp on 1 leg only but can see no examples or description of how to do this. I only want to send rtcp on the incoming a leg is this possible, and if so how do you do it? Thanks Chris

Where to go from here?
by T Fred Farmington 25 Feb '15

25 Feb '15

Let me begin with my apologies for again starting a new thread on this same topic. I am still not receiving the email notifications for postings so I am unable to Reply to them and thereby keep the thread contiguous. ================================= I tried having my SIP line vendor change the port to 5080 and that initially helped, but did not, by itself, fully establish the connection. I then made changes to the following configuration xml files conf\vars.xml I changed the default Password I defined the external_sip_ip & external_rtp_ip to be those of my SIP vendor conf/dialplan\public\00_inbound_did.xml I added in a new 'extension' which reflected the phone number of the 'caller' and defined the Action to take With these changes things started working (albeit in a simplistic manner) Then, in order to minimize the variables, I had my SIP line vendor return to its original port 5060 Things continued to work as before. So the 'outside' line port did not seem to make any significant difference. I will likely start a new thread about how to install in-house SIP phones onto the FreeSWITCH system (which xml files to modify, etc.) if I cannot make the correct guesses on my own. ( I hope that the list admin can 'knit' these various threads back into a single consolidated thread ) Thank you for your advice/assistance.
