Hello, When the following scripts were tested, it seems to do the memory leak. Please teach when there is a problem in this script. -- test script -- session.execute("ring_ready"); session.answer(); session.setVariable("ringback", "%(1000, 2000, 440, 460)"); var bleg = new Session(); var sound_wav = "sounds/test01.wav"; var sound_leg = "both"; var op = "api_on_answer=uuid_broadcast "+session.uuid+" "+sound_wav+" "+sound_leg; var ret = bleg.originate(session, "{"+op+"}" + "sofia/gateway/profile0_gateway1/1000"); if(!session.ready()){ return; } if(!ret){ // bleg not answered. var sound_wav = "sounds/test02.wav"; session.streamFile(sound_wav); if(session.ready()){ session.hangup(); } return; } if(bleg.ready()){ bridge(session, bleg); }

Replace Internal IP with External IP in From Header
by Code Ghar 01 Feb '10

01 Feb '10

I followed the example in Freeswitch behind NAT ( http://wiki.freeswitch.org/wiki/NAT_Traversal#Freeswitch_behind_NAT) In the Contact header of invite sent to an external gateway, I see sip:extension@ExternalIP:port but in the From header I see sip:extension@InternalIP. How can I change the From header of SIP message so that it displays the external IP instead of internal IP? The reason for doing this is that the external gateway authenticates and authorizes call based on the IP in From header. They expect an external IP and not an internal IP.

SS7 & MGCP support
by Abid Saleem 01 Feb '10

01 Feb '10

Hi, I am new to FreeSwitch. Please help me answer my following questions I could not find on wiki documentation. · Since it is a softswitch also, does it support SS7, MGCP and Megaco protocols to control media gateways? · Does it support call shops business model? · How to add new SIP user accounts into it that can be used to register to it. I know one way is to copy and paste 1000.xml file and edit it in the conf/directory folder. What is the optimal way to do this task?o Is there any GUI available. If yes how can I make it work and private label it.? Thanks for your great help.

Re: [Freeswitch-users] CPS per mod_sofia profile limited?

There is a tradeoff between cps and audio quality and timing accuracy. Try -vm -nocal if you want to mimic 1.0.4 we don't discuss performance here.

Yes, 1.04 offered a lot better performance in my test scenario, using the same call scripts.

I'll adjust the lengt of the call to 30 or 60 seconds and then try to see how many calls we can have. That's in the end what matters really and not cps on it's own.

CPS per mod_sofia profile limited?
by Robin Vleij 31 Jan '10

31 Jan '10

Hi guys, Doing a bit of testing / benchmarking with FS 1.04 (and 1.05 SVN). Found out some interesting things, I think. The setup is like this: SIPP Client -> FS -> SIPP Server The dialplan is as simple as it gets: <extension name="test-out"> <condition field="network_addr" expression="^130\.244\.190\.150$"/> <condition field="destination_number" expression="^(\d+)$"> <action application="set" data="proxy_media=true"/> <action application="set" data="hangup_after_bridge=true"/> <action application="bridge" data="{sip_contact_user=transit}sofia/gateway/${distributor(gwg1)}/$1|sofia/gateway/${distributor(gwg2)}/$1"/> </condition> </extension> For the rest it's running CSV cdr's, commented out all modules I'm not using, etc etc all that I could find on the wiki and the Interwebs. Hardware / OS: from the shelve quadcore Xeon, debian 64-bit, 12GB memory. SIPP is running a 500ms RTP pcap and the other side echos back. I had a few test setups then: 1: FS SVN, 1 sofia profile where the gateways were configured and the server_IP:5060 was used. 2. FS SVN, 2 sofia profiles where the gateways where in an seperate profile (server_IP:5070) and the "customer facing" side was the original profile. 3. FS 1.04, same as above 4. FS 1.04, 4 sofia profiles, distributor to spread load over 2 incoming and 2 outgoing profiles. Now the interesting thing was that under 1 I could go up, almost without any CPU load, to 50cps. As soon as I went over this, calls where handled slower and "ongoing" calls would pile up untill it became really slow. CPU load went to 100% on the FS process (both user and system time). Lots of interupts and context switches. No throughput anymore untill I lower and wait till the "buffer" is empty and FS is keeping up again. Under 2, I was able to increase the CPS to about 100 with the same effect. 3 then went much better, I was able to increase CPS to about 200 cps and response times in SIPP went up slighty untill it just hits some kind of limit and calls are handled slower. 4 is pretty cool. Here I can run 2 sipp clients both doing 150cps to the gateways that are spread on the distribution module, so I spread traffic over 2 profiles. With 300 cps in total, FS is keeping up and I have 30% idle CPU. However, increasing to over 300cps gives problems again, even though I have idle CPU left! All in all, I have a feeling that a single sip profile can't run more than a certain limit untill it gets into some problem. Depending on if I'm running SVN or 1.04 that limit seems to be 50cps or a bit higher. After that limit it starts piling up "ongoing" calls, by taking time to handle them and when that limit gets too high it's too late. All in all really fine, I just set the system wide limit to a little under that "threshold". But when I'm running just UNDER the threshold it's not CPU that's a problem. Theoretically I should be able to run (based on the CPU usage at 300cps) about 400cps. When running at 300 I get SOME failed calls and I see "switch_core_state_machine.c:525 a9a60636-0cea-11df-85a1-09c991f2afc5 Timeout waiting for next instruction in CS_NEW!" in the console. I didn't find much on how people do high cps setups and it feels a bit like a "friday afternoon solution" to run multiple sofia profiles on the same machine in order to max out the system. Maybe I'm missing something and I know it's not an exact science this, but I'm not sure "all is OK" because I'm not slowly getting to a 100% cpu (or disk / network) usage, I hit some kind of limit after which stuff goes wrong. Anyone any input! /Robin

Inbound sip invite from external gateway
by juan camilo ospina quintero 31 Jan '10

31 Jan '10

hi to all im already do the integration with. Freeswitch sends invite messages to sailfin, in sailfin there is a sip servlet that acts as a proxy, this means it receives the invite from extension1000 and send the invite back to freeswitch at extension 1001, but i get the freeswitch messages go to sailfin, but i dont get freeswitch to understand sailfin messages. there is my configuration for sending messages and for receiving messages In /freeswitch/conf/dialplan/default.xml <extension name="redirect"> <condition field="network_addr" expression="^192\.168\.2\.9$"/> <condition field="destination_number" expression="^1(\d+)$"> <action application="bridge" data="sofia/external/$0@127.0.0.1:5070"/> </condition> </extension> this works fine, it redirects the messages to sailfin in 127.0.0.1 In /freeswitch/conf/dialplan/public.xml <extension name="receive"> <condition field="network_addr" expression="^127\.0\.0\.1$"/> <condition field="destination_number" expression="^1(\d+)$"> <action application="bridge" data="sofia/internal/$0@192.168.2.9:5060"/> </condition> </extension> this doesnt work, i also use <action application="transfer" data="$1001 XML default/> instead <action application="bridge" data="sofia/internal/$0@192.168.2.9:5060"/> but still doesnt work, the invite that sailfin sends appears in the freeswitch console, but the 1001 extension doesnt get it _________________________________________________________________ Keep your friends updated—even when you’re not signed in. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/so…

Re: [Freeswitch-users] Multiple DTMF on group_confirm_key

If the both answer you can hangup on the one who entered the wrong or no info. The winner is whichever one exits the script first and is not hungup.

Multiple DTMF on group_confirm_key
by lakshmanan ganapathy 31 Jan '10

31 Jan '10

Hi all, I've experimented with group confirm key and group confirm file. It works great. However, I was unable to give multiple DTMF digits to get the confirmation. I've set group_confirm_key=1234, I thought it will ask the 4 digits from the user. But it simply taken 1 and when the user presses 1, the call got bridged. Is there any way to specify multiple dtmf to be confirmed??

Strategies for reliably detecting nat on B-leg?
by Bill W 31 Jan '10

31 Jan '10

Hey All, I know FreeSWITCH has the agressive-nat-detection parameter for sofia configs which will detect NAT on an incoming call. So we know if the A-leg is natted. The question is, are there any reliable ways to detect nat at the destination before bridging that call? One could assume that if the destination is a gateway, then it would be okay to bypass-media. Also, one could check the sofia registry and assume that if an endpoint is registered to FreeSWITCH that it is NATted and therefore no point in trying to bypass media. But neither of these options seems 100% reliable. Thoughts? Suggestions? Thanks! Bill W.
