Bridging from Event Socket API
by Klaus Teller 03 Dec '08

03 Dec '08

Hi Folks, so far i could understand how to bridge calls with Javascript. I'm trying to do the same with Java via the Socket Interface. My first trials weren't successful. maybe you can help me understand what is goin on. What i want to do is to bridge an existing leg (Unique-ID is known) to a party that wasn't yet dialed (Unique-ID unknown). With javascript it is something like: session.bridge("sofia/internal/1002"); How do i do this using the event socket interface? what application/command would i use with which arguments? One way i tried to do this is to orginate a call to 'sofia/internal/1002' and bridge the two existing legs using uuid_bridge. Unfortunately, it wasn't successful. The only message i had on the FS console is: 2008-12-02 16:57:34 [DEBUG] switch_core_session.c:693 switch_core_session_queue_private_event() Send signal sofia/internal/1001(a)192.168.1.121 [BREAK] Any idea what i'm missing? Thanks, Klaus. -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger

Unstable att_xfer
by x y 03 Dec '08

03 Dec '08

Hy! I have tested several times so far the att_xfer function of the freeswitch, and I've found it unstable. I'm using a similar code to the example at the freeswitch wiki, and sometimes a call isnt transfered. The att_xfer works fine in the cases as I figured out from the log, when the switch_ivr_bridge comes back with a "ending bridge by request from read function" message. When it comes back with a "request from write function", the two channels dont get bridged together: they cant hear each other form the other side, and they dont even realize that the other hangs up. I have pasted some logs about this a week ago into paste bin, but if you wish, I could paste new logs with the newest fs. Could it has something with silence, because I think there are more failures when I dont talk into the phones? Im using latest fs, and sip phones without built in transfer.

TLS receiving calls
by matrim 02 Dec '08

02 Dec '08

Hi, I'm having problems using TLS to receive calls. I'm using a Nokia N95 to test TLS against freeswitch. I can register my client against freeswitch and make outbound calls to the test numbers (e.g. 9999). I can also make calls to other users registered over UDP. However if I try to make a call to a user registered over TLS the leg of the call to that user always goes via UDP. e.g. 1000 registered via TLS 1001 registered via TLS 1002 registered via UDP 1003 registered via UDP 1000 -> 1002 works ok 1003 -> 1002 works ok 1001 -> 1000 Doesn't work. The leg of the call between freeswitch and 1000 tries to setup via UDP 1002 -> 1000 Doesn't work. The leg of the call between freeswitch and 1000 tries to setup via UDP === >From looking at some of the documentation it seems to me that the issue may be with the "tls-bind-params" being "transport=tls". The phone I'm using doesn't add the "transport=tls" parameter, and only uses "sips:" to specify that the connection is via TLS. I tried setting "tls-bind-params" to a blank string but it didn't change anything. Is there any way to receive calls over TLS if you don't specify "transport=tls" in your contact string during registration? According to RFC3261 the use of the "transport=tls" parameter isn't recommended anymore and is now deprecated. -- View this message in context: http://www.nabble.com/TLS-receiving-calls-tp20771637p20771637.html Sent from the Freeswitch-users mailing list archive at Nabble.com.

Support for Junghanns duoBRI
by Sergey Kirillov 02 Dec '08

02 Dec '08

Greetings, Can somebody tell me, if it is possible to use duoBRI card (http://www.junghanns.net/en/duobri_express_produkt.html) from Junghanns.net together with Freeswitch? I've found that this card has Zaptel drivers, and Freeswitch has mod_openzap. On the other side, I saw somewhere in wiki that Freeswitch does not support BRI at all at the moment. Please confirm or allay my apprehensions.

Listen to a file, while recording?
by Dennis 02 Dec '08

02 Dec '08

hi, i would like to be able to listen to conversations, while they are ongoing. this should not happen over a phone. i would like to be able to have a link or something in my admin-area, where i can click, if i want to listen to a conversation. i thought about to start a record with socket inbound on a specific uuid and while the recording is done, i would like to play the file. but i have the feeling, that this is not possible, while the file is not finished. is there a way to stream the audio over the web? thanks for your help.

I need to barge in again and add to my last post with this email from Voxeo support. Here is their response to the port binding conflict and it brings up a possible problem if FreeSwitch will be looking for Prophecy at that port? I assumed it would if I set up the extension right but now I don't know and need your assistance with this issue ... as well. Thank you. MESSAGE: Hi Mark, You are correct in that having multiple applications binding to the same port can cause a bundle of problems. You can configure Prophecy to stay away from port 5060, but then the question is whether FreeSwitch will be looking for Prophecy at that port (if its assuming that it's residing on a different box). Port 5060 is the standard for SIP traffic. To get Prophecy off 5060 you will need to edit the config.xml and callrouting.xml files. You will need to search out all instances of "5060" and replace with, perhaps, port 5068. For instance: <item name="ListenOnIP1">0.0.0.0:5068</item> <item name="ListenOnIP2">0.0.0.0:5061</item> <item name="ListenOnIP3">0.0.0.0:5067</item> <item name="ListenOnIP4">0.0.0.0:5063</item> <item name="ListenOnIP5">0.0.0.0:5064</item> <item name="ListenOnIP6">0.0.0.0:5065</item> instead of this... <item name="ListenOnIP1">0.0.0.0:5060</item> <item name="ListenOnIP2">0.0.0.0:5061</item> <item name="ListenOnIP3">0.0.0.0:5062</item> <item name="ListenOnIP4">0.0.0.0:5063</item> <item name="ListenOnIP5">0.0.0.0:5064</item> <item name="ListenOnIP6">0.0.0.0:5065</item> Regards, Jeff Kustermann Voxeo Support ? -----Original Message----- From: mszlazak(a)aol.com To: freeswitch-users(a)lists.freeswitch.org Sent: Mon, 1 Dec 2008 10:40 pm Subject: Re: [Freeswitch-users] Problems with Mod_openMRCP Just to follow up. Moshe Yudkowsky has an article on "Routing calls from FreeSwitch to Prophecy":? http://www.prophecy2006.com/node/145 My problem is that Freeswitch and Prophecy need to be on the same machine BUT both need to bind to port 5060 so I'm getting errors from one or the other depending who's running first. So can I change what port(s) FS uses and that way avoid this conflict? Maybe, this might let me bridge the call via FreeSwitch to Prophecy similar to what Moshe's article discusses??? -----Original Message----- From: mszlazak(a)aol.com To: freeswitch-users(a)lists.freeswitch.org Sent: Mon, 1 Dec 2008 4:44 pm Subject: Re: [Freeswitch-users] Problems with Mod_openMRCP Does "bridging" a call from FS to Voxeo's Prophecy server require openMRCP? If not then the other issue I might have is a database look up that is part of the dialogue that maybe need as the person response to prompts from the asr. It's possible to run a php script for the database stuff that Prophecy might need or could that happen via Javascript in FS?

As i have clearly stated in 2 previous emails, the man has decided to discontinue the openmrcp project. So now we are left with the remains of the module and discontinued code.? This was not our decision it was his. Since the author of openmrcp has stated that he has a new unimrcp we are certainly going to work towards getting mod_unimrcp to replace mod_openmrcp.? He had already commented on that previous thread to state he is willing to consider making a new module. Some people use it without issue which may mean that the crash you reported is windows specific and I do not have a working lab of any mrcp capbable system to try it against in unix for that matter.? I have a list of work to do from here to the moon and back so on an issue like this, unless someone can hand me login credentials to some box and give me a phone number to dial to reporduce the issue, it will be a long time until we can deal with it.? And the question arises, should we bother working on it anymore if the lib has been abandoned and we cannot even get any support from it's author which is where the problem most likely lies. I try not to get too annoyed by these remarks about what we *ought to do* because I know people lose sight of how much of the work to support the project is done by a small group of 3 people and not the 2000 people it appears to be from the outside looking in. (I've been answering email for 4 hours now) My suggestion is to pool some cash and pay the guy to make mod_unimrcp for FS that we can maintain in tree knowing the development can be supported by the original author.

Without wishing to sound like a stuck record, one thing that you guys really ought to do is to decide what's supported and what isn't, and make this obvious - for example, move unsupported modules to a different place in the tree, don't have them built by default, etc.? MRCP is in the specsheet on the Wiki.? Otherwise folk like Mark and I spend time installing stuff, go round in circles a bit trying to make it work, and then find out (a) that it doesn't and (b) it's not going to be fixed because it's not supported.

I say this because I can't seem to get it to work at all with the example in that Mod_openmrcp wiki page but I thought it might because I'm not be using the right Cepstral software (freetrial download versus the paided for SDK) or that I'm not using the right port numbers or something else I didn't do. I used TcpView to look at local port associated with my Cepstral software and changed a few things but still nothing. I changed the loglevel setting to 7 in the wiki's example but I don't see the kind of output on the console that I would expect for debug mode. Thanks.

Question about wrapping libfreeswitch
by Woody Dickson 02 Dec '08

02 Dec '08

Hi, I am sorry again for sending another email to the group again. I am working on embedding libfreeswitch to provide better monitoring. The first thing I attempt to do is to run the sample code provided in the website: #include <switch.h> int main(int argc, char **argv) { switch_core_flag_t flags = SCF_USE_SQL; int nc=0; /* this is for 'no console' mode, FALSE console is there, TRUE it isnt */ const char **err = NULL; /* error value for return from freeswitch initialization */ #define LOGFILE "freeswitch.log" static char *lfile = LOGFILE; /* if NULL no logfile is generated */ switch_core_init_and_modload(*lfile,flags,err); switch_core_runtime_loop(nc); switch_core_destroy(); return (0); /* per C89 spec */ } But this code gives me segmentation fault when executing it. This piece of code is supposed to start up freeswitch and run it is a loop. Does anyone see what is wrong with it? Does anyone have any working example that I can refer to? Thanks, Woody

Problem with Freeswitch capturing DTMF
by Keith Wood 02 Dec '08

02 Dec '08

Hi, I am wondering if I am the only one getting this problem or not. When sending in DTMF to freeswitch, freeswitch is not always capable of capturing all the DTMF being sent. For instance, sending 1000 to freeswitch may end up becoming 100 or 10003 becoming 1003. Am I the only one getting this strange issue? If anyone know how to fix this problem, I would greatly appreciate it. Regards, Keith
