How to report bad HDLC frames?
by Sadhika Sharma 11 May '11

11 May '11

In freeswitch logs I can see the received data but only for those packets which are received accurately (HDLC framing is OK.) How can I see bad HDLC frames (if there are any) in the logs? -- Sadhika

Freeswitch Code compromised? Hacked?
by Sidharth Kshatriya 11 May '11

11 May '11

OK. So maybe I'm being paranoid. I downloaded Freeswitch 1.0.7 from http://latest.freeswitch.org/ <http://latest.freeswitch.org/>I get the following startup message: FreeSWITCH Version 1.0.7 (hacked-20110509T092215Z) Started. Now in common parlance "hacked" could mean "built". But I still* *just* *want to know if the code wasn't compromised in any way and any cheeky hacker left a message in "plain sight" like osama :-) Is this startup message okay? Can it be changed to something a little bit nicer / less alarming le.g. built-20110509T092215Z ? Now another question: I downloaded this on May 8 from http://latest.freeswitch.org/. There seems to be another download dated May 10. Has 1.0.7 not been released yet? Is it still being finalized? -- Sidharth Kshatriya www.sidk.info

Can anybody recommend some good sip trunk providers?
by Sidharth Kshatriya 11 May '11

11 May '11

Dear All, I'm thinking of buying a sip trunk from https://store.freepbx.com/ . A single trunk is $24.99 a month. I'd like to be able to support 2-3 simultaneous calls to my IVR on a single US DID number. So that is ~$75 a month. Any cheaper options? Other providers ? Thanks, Sidharth -- Sidharth Kshatriya www.sidk.info

Major deployment of outbound FAX on latest version of Freeswitch question
by Andrew Keil 11 May '11

11 May '11

To Freeswitch developers, RE: MOD_SPANDSP I have a client that wishes to send 20,000 to 30,000 outbound faxes daily and has requested me to quote for a Freeswitch setup that will support this. I notice the comment on the mod spandsp wiki page: "We are finishing mod_spandsp. It requires full field testing now." Well this could be a perfect opportunity :) I need to understand the following: 1. Does the mod spandsp support the TDM cards (Sangoma) to send faxes out over E1 (Euro ISDN)? 2. How many concurrent faxes out have been tested using mod_spandsp ? Was this over SIP or over ISDN? 3. What is the preferred Operating System to use (since basically I would prefer to use the same one as the main developer of mod_spandsp)? 4. Where do I source the latest email2pdf to test that out? That should be enough to kick this question off. Kind Regards, Andrew Keil

mod_crd_sqlite entry limit and sqlite segfaults on triggers
by Neven Boric 10 May '11

10 May '11

Hi, By looking at the code, I believe there is no limit on the number of rows mod_cdr_sqlite will add to the cdr table. This could lead to (eventually) eating all RAM if you DB is in tmpfs or eating all disk space if it is stored on disk. Is this correct or am I missing something? To correct this I tried to add a trigger to the table along the lines of: CREATE TRIGGER IF NOT EXISTS CDR_LIMIT AFTER INSERT ON cdr BEGIN DELETE FROM crd WHERE rowid <= (SELECT MAX(rowid) from cdr) - 100000; END and no matter how I try to add the trigger, I get a segmentation fault when the code calls sqlite3_exec in switch_core_db_exec. Currently I'm blaiming SQLite, as there is a somewhat similar issue involving triggers reported for versions older than 3.5.4 (FS is using 3.3.13) http://sqlite.org/cvstrac/wiki?p=DatabaseCorruption Of course I could just execute the delete statement manually after every insert, but it is uglier (more costly, non atomic). Has anyone any experience using triggers with the sqlite version included in FS? Or has anyone tried other solution to limit the number on entries on the cdr table? Thanks in advance Neven Boric

Does FS supports speex with ptime=40?
by mayamatakeshi 10 May '11

10 May '11

I am testing making calls with x-lite 4. Although it doesn't send a ptime in its INVITE/SDP, i can see it is sending RTP using ptime=40 as I can count 25 UDP packets per second. When I try to bridge this to PSTN which responds with PCMU, at the PSTN side I hear trembling/metallic/robotic audio. I was suggested to set FS to use ptime=40, so I've tried setting codecs with speex@8000h@40i But it doesn't work. I get: "488 Not Acceptable Here" (Reason: Q.850;cause=88;text="INCOMPATIBLE_DESTINATION) So it seems only ptime=20 is supported as listed here: http://wiki.freeswitch.org/wiki/Codecs#Transcodable_codecs Could mod_speex be changed to work with ptime=40 too? Or is there anything else that i can try? regards, takeshi

Call state notifications
by Rogelio Perez 10 May '11

10 May '11

> Event sockets is what you want.... Thanks Ken, it looks like Event Sockets will do the job, but I'm not sure how. I'm testing with netcat listening on port 8084, and then I've managed to connect to it by inserting this line on the dialplan: <action application="socket" data="127.0.0.1:8084 async full"/> Since I dont need to control the call but only receive notification events about the channel state changes I assume I have to send the command "myevents\n\n\" and the pass the variable socket_resume:true back, but this doesnt seem to be working. sendmsg call-command: execute execute-app-name: myevents\n\n\ socket_resume:true This is my first attempt to write an application for FS so I need some guidance. Thanks!

many outgoing calls with mod_lcr at the same time possible?
by Anestis Mavro 10 May '11

10 May '11

Hello Freeswitchers, Is it possible to make many outgoing calls with mod_lcr at the same time? An example would be to redirect an incoming call to two mobile phones and ring them simultaneously. With a "normal" bridge we can achieve this, but what about having also LCR (billing and limit included) involved? Regards Anestis
