xml_cdr: end_epoch is 0, billsec are negative - how does this happen?
by Christian Benke 26 May '11

26 May '11

Hello! My xml-cdrs are saved with an end_epoch of 0/end_stamp 1970-01-01 and negative duration, billsec etc.(e.g. -1306336317) - start_epoch/start_stamp values are correct. What's causing this behaviour? I'm running FreeSWITCH on a OpenVZ-Container(2.6.32-5-openvz-amd64) - could there be a relation to the cdr-issue? Regards Christian

Making an outbound call to a cell phone and letting the callee interact with a JavaScript program
by Yungwei Chen 26 May '11

26 May '11

Hi, I am wondering which application allows me to do the following: 1. make an outbound call from a SIP phone to a cell phone. 2. When the call is answered, run a JavaScript application (so the caller can interact with the JavaScript program.) Thanks.

rtpmap line missing on answer
by Sean Eichhorn 25 May '11

25 May '11

I have a freeswitch system that (for the most part) works flawlessly for me. However, I need to have an additional rtpmap line in the SDP when a call is answered. My client sends the following SDP upon answering the call : m=audio 17214 RTP/AVP 0 19 101 100 c=IN IP4 192.168.98.79 a=rtpmap:0 PCMU/8000 a=rtpmap:19 CN/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=rtpmap:100 X-NSE/8000 a=fmtp:100 192-194 Freeswitch forwards the following SDP to the external gateway : m=audio 20654 RTP/AVP 0 19 101 c=IN IP4 66.223.187.208 a=rtpmap:0 PCMU/8000 a=rtpmap:19 CN/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 The other information appears fine. Everything works, but my client-side is not receiving the a=rtpmap:100 line. This issue appears regardless of whether or not I'm in proxy mode, bypass mode, or neither. Using "sip_append_audio_sdp" has no effect on the answering SDP, only the initial offer. Any ideas? Thanks in advance,

Playing a wav file on a remote web server
by Yungwei Chen 25 May '11

25 May '11

Hi, I am currently using the following javascript snippet to play a wav file on a remote web server. I'm wondering if there's another way to do it without involving a local file, just like mod_shout. Thanks. function on_dtmf(session, type, digits, arg) { dtmf_digits += digits.digit; console_log("dtmf_digits=" + dtmf_digits + "\n"); return(true); } var ttsUrl = "http://127.0.0.1/tts/getWav.aspx?text=please%20enter%20your%204%20digit%20p…"; var file = "/tmp/tts.wav"; fetchURLFile(ttsUrl,file); session.streamFile(file, on_dtmf);

DTMF Problems! In-band detection patchy, rfc2833 not working!
by Sidharth Kshatriya 25 May '11

25 May '11

Dear Friends, I'm using a voip carrier Voicenetwork.ca (recommended by someone on this list). While I'm generally happy with their service there seems to be one fatal problem: My IVR does not recognize DTMF! I have set <param name="dtmf-type" value="rfc2833"/> in both sip_profile/internal.xml and sip_profile/external.xml The symptom of the problem is that making a call via skype will *always*make the IVR recognize the DTMF while using something like a mobile phone *almost always* won't! I've tried in-band detection too. I'm making international calls into my IVR and the reliability of the in-band detection is not so good, possibly because of the quality of the call. Can someone please help me? Thanks, Sidharth -- Sidharth Kshatriya www.sidk.info

FS not recognizing 200 OK after far-end call is answered
by Blake Sevier 25 May '11

25 May '11

Hi all, I’m new, so please bear with me. My setup is fairly basic, and the routing all seems to work just fine: FS receives call from an OpenSIPS proxy, it answers the call, records it and plays back a short prompt before invoking the “bridge” function to place an outbound call via the same OpenSIPS proxy to an external SIP endpoint (in testing, just an Asterisk instance that answers the call). This all works just fine, except FS doesn’t seem to recognize the 200 OK it receives back for leg b after the Asterisk instances answers the call. It apparently does recognize/accept the 100 Trying, as FS doesn’t send additional INVITEs. I’m not seeing any issues with the SIP messaging received by FS – it’s apparently formatted correctly. To note, I’ve also tested calls direct to the Asterisk instance (bypassing OpenSIPS proxy), and get similar results. My guess is that I’ve got something incorrectly configured within my dialplan?? However, not sure how to debug any further to figure out why the 200 Oks are not being recognized. Eventually, after 60s, FS ends the call with a NO_ANSWER. Below is a link to a full call trace from FS – from start of call to when I see multiple 200 OKs from Asterisk. http://pastebin.com/bmEtiW9X Any help would be greatly appreciated. If any further details are needed, please let me know Thank you!!! Blake

transfer to extension without pattern matching
by Adam Kelloway 25 May '11

25 May '11

Hi there, The wiki page describing transfer (http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_transfer) states the following: "Immediately transfer the calling channel to a new context. If there happens to be an xml extension named <destination_number> then control is "warped" directly to that extension. Otherwise it goes through the entire context checking for a match." Is this a correct statement? It seems that even when I try to transfer control directly to an extension, the entire context is still checked for a match. I am using the following: .. <application="transfer" data="test XML default"/> .. <extension name="test"> <condition field="destination_number" expression="^test$"> ... </condition> </extension> Is there a way to disable the pattern matching/dial plan processing? Thanks, Adam

Errors while sending faxes
by Mathieu Lautram 25 May '11

25 May '11

Hi all, After sending faxes (it works very well know, thanks to Anthony Minessale) , sometimes I've got errors like that: - Disconnected after permitted retries - No response after sending a page - Received a DCN from remote after sending a page - Received bad response to DCS ot TCF - The call dropped prematurely - Timed out waiting for initial communication Those faxes are about 25% of all faxes that I send. I'm using the last git version. Where this problem comes from? Is there a way to fix this? I know that sometimes the remote end could be broken or could be an old fax machine, but it seems strange that I have so many errors like that. Thank you for your help :-) -- Mathieu LAUTRAM Application developer BJT Partners - FRANCE +33 1 79 75 99 60 +33 6 61 59 07 25
