Question on SpanDSP modem and correct usage of t38_gateway
by Dmitry Sytchev 07 Mar '13

07 Mar '13

Hi all We are trying to use SpanDSP modems with FS and hylafax for outbound faxing. We dial through FS0 modem to PSTN gateway. When FS receives a reinvite to T.38 from GW, it never replies with 200 OK, instead it begins to send t.38 data, which is ignored by gateway as it still waits for response on T.38 reinvite. After 30 seconds timeout GW sends BYE. Should I open ticket or we just need correct t38_gateway application params? What is recommended setup if there is a hylafax behind Freeswitch, and PSTN gateway is T.38-capable and sends T.38 re-invite by itself? I tried different combinations from wiki, results are different in details but one thing persists - there is no 200 OK from FS to T.38 re-invite on outbound call through FS0 modem. -- Best regards, Dmitry Sytchev, IT Engineer

Re: [Freeswitch-users] Door intercom/gate controller
by Mr Nathan Downes 07 Mar '13

Ahh it turns out fibre provider wont reprovision all the ATA's to use OOB so I am going to have to give this a go.. Endpoint 1 = Gate controller = only accepts OOB Endpoint 2 = Standard analogue phone on ATA = only generates inband Person uses endpoint 1 to call resident who needs to dial code to open gate so start_dtmf has to work from endpoint 2 to endpoint 1 when it is endpoint 1 that calls endpoint 2. I'll test it out and let you know the results! P.S. I love freeswitch and the work you guys have done, I have never seen such a flexible simple software that is still so complex there is a way to do anything you can imagine is possible!

Start_dtmf worked if I called the gate controller from the phones, but not in the other direction which is how it will be used. It has been resolved as it was discovered the ATA devices inbuilt to the fibre ONT have an option for OOB DTMF, enabling this on the POTS profile allowed the device to function. I am still interested on how I could of got it to work though, is start_dtmf a one directional app?

Rather than out the b-leg.. It works fine when I call a SPA502g as it will provide RFC 2833.. is there some trickery I can achieve this? Or am I just doing it wrong??

mod_xml_curl and https
by Alexander Haugg 07 Mar '13

07 Mar '13

hi all, since view hours i try to make a https request to a c# sslstream class. the same request works fine with the browser. In my descriotion the freeswitch is the web client and the c# sslstream side is the server. Is it possible to configure the xml_curl.config.xml to trust any server certificate and the certificate comes only from the server (the same that's working with the browser)? With all configurations that i try the client sends an Encryptet Alert and a [Fin, ACK]. At the moment, the server side use a *.pfx cert gerneratet with openssl. Thanks for your help.

FreeSWITCH Sometimes Doesn't Fire Custom Event
by Zoltan Medveczky 07 Mar '13

07 Mar '13

Hi, I'm encountering an issue where FS on occasion doesn't seem to dispatch a custom event from the dial plan. I would estimate that this occurs on average approximately once in every 15 calls. Here is the dial plan extension in question: <extension name="null_fwd2queue19"> <condition field="destination_number" expression="^(null_fwd2queue19)$"> <action application="set" data="CheckAgent=no" /> <action application="set" data="CheckAgentLoggedIn=no" /> <action application="set" data="CheckLoad=no" /> <action application="set" data="MaxLoad=null" /> <action application="set" data="LongestWaitingTimePermitted=null" /> <action application="set" data="MaxWait=null" /> <action application="set" data="QueueName=null" /> <action inline="true" application="event" data="Event-Subclass=Global_Reach::QueueCall,Event-Name=CUSTOM,GR_CallState=CallQueued" /> <action application="playback" data="local_stream://moh" /> </condition> </extension> And here is the normal sequence of events received by the client application which is connected to the event socket in inbound mode: CHANNEL_ANSWER CUSTOM PLAYBACK_START When the issue occurs, the sequence is the following: CHANNEL_ANSWER PLAYBACK_START This would seem to imply that the event queue is not getting blocked since the client app does receive all events subsequent to the CUSTOM event. It's not clear to me at this point if the event is not getting queued at all or if it is simply not being sent out on the event socket. I've started to debug the issue and have determined that it is at least getting as far as the call to "switch_event::switch_fire_event_detailed()" in "mod_dptools". It's probably worth mentioning that the dial plan XML is being loaded dynamically for each call via a Lua script as opposed to a static configuration file. Here are the details on the environment where I'm able to reproduce the issue: FS Version: 1.2.5.3 OS: RHEL 5.8 (Tikanga) Kernel: 2.6.18-308.el5 CPU: x86_64 Please let me know if you require any additional environmental information. I will amend this ticket as I uncover more data points. Thanks in advance... Cheers, - Zoltan

.NET managed code - call count
by Malay Thakershi 07 Mar '13

07 Mar '13

Hello, I have a .NET managed module handling calls transferred to it via dial plan. Now, I would like to maintain concurrent call count and decline the call if it has reached certain limit. What I do is, have a static variable to track this. *private static int mIntCurCalls = 0;* Then, when Run() is executed, I *mIntCurCalls++* after answering the call. I perform check *if mIntCurCalls > "max allowed calls"* then I play a message and hangup. I *mIntCurCalls--* this when call is hung up. Since last few days users have been complaining they get "busy" or "number not available" when dialing toll-free number. However, I don't see them getting the message that I have in the code. Is the method of keeping call count correct? Thanks.

Extract audio from PCAP
by Avi Marcus 06 Mar '13

06 Mar '13

I've have some really large PCAPs sometimes and wireshark just dies trying to decode the audio in them. All the links for audio extraction on voipinfo seem really old. Is there something else to extract the audio from pcaps? Or some command to to pass tshark to just save all audio as a .wav file? What does voipmonitor use? I think I asked this before... Thanks, -Avi Marcus
