Is Session.uuid the same as caller_profile/uuid in the cdr.xml?
by Brian Deacon 31 Jan '09

31 Jan '09

Hiya, So my xml cdr has just one uuid in it. (I guess the shape and contents of this are configurable? But I'm using however it defaults.) cdr/callflow/caller_profile/uuid I wouldn't have thought caller_profile would be where I'd find a session.uuid, but since that seems to be the only uuid in the cdr, I'm guessing that's it if it's there. Is that it? I'm going to be logging the start of a phone call using the session uuid as the PK for a log record and need to be able to update that record later with call duration information when the CDR comes through after hangup.

Spanish prompts for mod_say

Does anybody know where I can find Spanish prompts for mod_say? I see the English ones in http://files.freeswitch.org, but no other languages. Thanks, Marc

compiling mod_openzap
by Dan 30 Jan '09

30 Jan '09

Hi guys I pulled FS from trunk today to build some debian packages and ran into this error when building mod_openzap: mod_openzap.c:2197: warning: assignment discards qualifiers from pointer target type I went ahead and changed the line at 2178 in mod_openzap.c from char *pcapfn = NULL; to const char *pcapfn = NULL; Do you see any problems with this change?

I don't know, I must have had a momentary lapse of reason .. but at least I documented it!

Is pyrun available from mod_commands (and thus to mod_xml_rpc?)
by Brian Deacon 30 Jan '09

30 Jan '09

Maybe this is just missing documentation for mod_commands. I can run pyrun from fs_cli. Does that mean I can run it from mod_xml_rpc? Brian

Strange Performance when using as SBC
by rod 30 Jan '09

30 Jan '09

Dear list, I've been playing with freeswitch for some time (2 months) and the fact is that I'm very pleased with the functionnalities of this software. I'd like to use FS as a SBC handling media and I'm doing some tests with sipp to load the machine but I'm unable to bridge more than 60 calls without seeing the CPU being loaded at 100%. I'm sure something is going wrong with my setup but I'm unable to see what. The test machine has the following specs: Athlon XP 3500+ with 2GB of memory (I know this is not a high end machine :p) Freeswitch:/opt/freeswitch/log# cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 95 model name : AMD Athlon(tm) 64 Processor 3500+ stepping : 2 cpu MHz : 2199.973 cache size : 512 KB fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow up rep_good pni cx16 lahf_lm svm extapic cr8_legacy bogomips : 4402.97 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp tm stc I installed FS on a fresh debian 64: Linux Freeswitch 2.6.26-1-amd64 #1 SMP Sat Jan 10 17:57:00 UTC 2009 x86_64 GNU/Linux I set the ulimit parameters like those on the website: freeswitch@internal> ...

Crash Protection [Disabled] Max Sessions[1000] Session Rate[100] SQL [Enabled] The test is very simple: sipp dial 9999 that matches in my FS dialplan and this is bridged to an other FS machine playing music on hold. When I launch "top" I see after 30 to 40 s that FS consumes all the CPU ressources (with a mean of 50-60 % before), with 80 calls. When I set 70 calls, I have to wait 70-80 s before seeing the same issue. Presence is set to false on the 2 profile. I have the same issue with FS 1.0.2 that' s why I tried FS 11560. When I use the FS machine as a router to test the packet per second performance, I'm reaching 100Mbps with 8000pps in each direction (from vlan 55 to vlan56) with less than 12% CPU. So that I don't think there's an issue with the network. Here is an "mpstat -P ALL 1" to show you what's happening suddenly with 70 bridge calls: 12:31:26 CPU %user %nice %sys %iowait %irq %soft %steal %idle intr/s 12:31:27 all 3,00 0,00 3,00 0,00 1,00 4,00 0,00 89,00 6241,00 12:31:27 0 3,00 0,00 3,00 0,00 1,00 4,00 0,00 89,00 6241,00 12:31:27 CPU %user %nice %sys %iowait %irq %soft %steal %idle intr/s 12:31:28 all 14,14 0,00 56,57 0,00 2,02 5,05 0,00 22,22 6035,35 12:31:28 0 14,14 0,00 56,57 0,00 2,02 5,05 0,00 22,22 6035,35 12:31:28 CPU %user %nice %sys %iowait %irq %soft %steal %idle intr/s 12:31:29 all 24,75 0,00 67,33 0,00 0,99 6,93 0,00 0,00 5483,17 12:31:29 0 24,75 0,00 67,33 0,00 0,99 6,93 0,00 0,00 5483,17 The CPU is going from 89% idle to 0% in less than 2 seconds. I know that I don't have to expect too much from this kind of hardware, but it seems strange that the CPU power vanished so suddenly. Thanks a lot for the guys that have read this long mail :p kind regards, rod

More troubles with SQLAlchemy and mod_python
by Brian Deacon 30 Jan '09

30 Jan '09

Greetings, So I see from nabble and on the wiki that others have had problems with sqlalchemy and the hangup hook, but I appear to be having a more basic problem. I'm running FS 1.0.2, python 2.4.3, and SqlAlchemy 0.4.7 Here's an extension in my public.xml that works: <extension name="Python_Test_On_5186"> <condition field="destination_number" expression="^6468715186$"> <action application="set" data="group_confirm_file=voicemail/8000/vm-hello.wav" /> <action application="set" data="group_confirm_key=4" /> <action application="set" data="call_timeout=60" /> <action application="set" data="destination_number_python= ${python(callcontrol.routing.DummyRouteHandler)}" /> <action application="bridge" data="${destination_number_python}" /> </condition> </extension> With this silly DummyRouteHandler.py: import os from freeswitch import * #import sqlalchemy def fsapi(session, stream, env, args): stream.write('sofia/internal/1000%10.48.5.207') (Note the commented out sqlalchemy import. Uncommenting the import gets me an "error importing module" or "error reloading module" in the fs_cli output) Oooh, and just now trying to reproduce I got my first crash. Thoughts? Brian

record session in fifo
by Tamas Cseke 29 Jan '09

29 Jan '09

Hello, we would like to distribute calls with fifo and record these sessions but we'd like to skip the recording while the caller is waiting. (we don't need to record the hold music, just the speech with the fifo consumer.) I tried <action application="set" data="RECORD_ANSWER_REQ=true"/> <action application="record_session" data="${callfilename}"/> <action application="fifo" data="myfifo in"/> but it doesn't work because the channel is answered immediately when the caller is pushed into the fifo. (I don't know if there exists any other channel flag that could be use here) I also tried fifo_record_template. but it records the session from the point of view of the consumer's session, and after the bridge the recording is stopped. we would like to record the whole session into a single file even after calltransfers moreover we'd like to use some kind of predcitive dialing which 1, originate a loopback channel via event socket 2, loopback-b channel is hunting the dialplan, wich decide routing, caller_id, the need for recordings and so forth, and bridge a sofia call 3. the record_session is running on the sofia channel with bridge_pre_execute magic vars 4 loopback-a channel is pushed into the fifo 5 a script get the fifo::info via event socket 6 originate a call to the consumer with the proper strategy with &fifo out application 7 sofia channel is bridged to the consumer 8 loopback channels die after transfers everything is recorded into one file. but the problem here is again the unwanted recording in the fifo while the caller is waiting Could you please advise me any solution, if there is? Thank you, Tamas
