T.38 via UPDATE request
by Peter P GMX 19 May '11

19 May '11

Hello, we have the following problem. 2 Fax machines are communicating via Freeswitch. One is externally attached via a Telco who is able to handle T.38. The other one is attached locally. When 2 Fax machines start syncing each other, the Telco sends a SIP UPDATE message with T.38 SDP, as it detects fax during the fax negociations. Freeswitch answers with an SIP OK message back to the telco, and I can see the T.38 SDP on the debug console of freeswitch. Then nothing happens any more until one of fax machines detects timeout. We have set proxy-media to true. However is was done during call setup when both machines communicated with G711 SDP. The UPDATE message was commited by FS to the telco, but was not sent to the other fax, so I think in this case Freeswitch is supposed to transcode between T.38 and G711 which it cannot do, as we know. How can I overcome this scenario? Is this a defect, should freeswitch send the UPDATE message to the other fax? Or is there a workaround? Best regards Peter Here's the UPDATE message: UPDATE sip:mod_sofia@82.115.xx.xxx:5080 SIP/2.0. Call-ID: 5283fe4e-334f-122d-d1b9-001517956764. Contact: <sip:212.91.xxx.xxx:5060>.

freeSWITCH segfault on openwrt
by Woody Dickson 18 May '11

18 May '11

Hi, I manage to get freeSWITCH to compile and run on openwrt, but then freeSWITCH keeps crashing when the number of calls reaches 25 consistently. Content of the core file returns nothing when opened with gdb. Does anyone have any clue as to why this is happening and how to fix it? thanks, woody

That looks like the problem I had with my FXS ports sending CID not understood by european phones. In which country are you / what kind of analog phones are you using ?

Call back from voice mail creates loop
by Tim St. Pierre 11 Mar '11

11 Mar '11

Hello, I'm trying to set up the option in voicemail so that users can return a call directly from VM. In my voicemail.conf.xml profile I have specified the dialplan as XML and the context as "internal", which is what I use for calls coming from our endpoints or authenticated users. In our internal dialplan, we do some pattern matching and call an appropriate lua dialplan script to do build a set of instructions. Problem is, the lua scripts are looking at the destination_number variable to decide where to send the call. This variable is still set to "voicemail" from when the user called into their voicemail. Shouldn't the voicemail app have set that to the number we want to call back? I used the info app to look at the variables, and I didn't see anything obvious. Is destination_number the correct variable to use in a lua script that generates a dialplan? -Tim

xml_curl and gateways
by Peter P GMX 21 Feb '11

21 Feb '11

According to http://wiki.freeswitch.org/wiki/Mod_xml_curl I'v tried to set up gateways dynamically, but I do net get it to work: I always get : "Invalid profile" My assumptions for a right xml answer back to FS are as follows, but I think at least one of it is false: 1. ) I start with <document type='freeswitch/xml'> <section name='configuration'> <configuration name='sofia.conf' description='RailsAdditionalConf'> 2.) I do not want to change settings, so I do NOT add a <settings> tag 3.) I want to enhance an existing profile, so I add a profile tag (<profile name='external'>) 4.) I assume that I can have an existing profile "external" in the xml conf files and can mix additional parts dynamically into the same profile 5.) Within the profile I want to add gateways, so I add a gateway tag (<gateways>) 6.) Then I add the gateways 7.) I add the closing tags Which one of the assumptions if wrong? The request I receive is as follows: {"key_name"=>"name", "action"=>"directory", "tag_name"=>"configuration", "key_value"=>"sofia.conf", "controller"=>"xml_curls", "hostname"=>"freeswitch", "section"=>"configuration"} I only answer once at startup with the follwing: <document type='freeswitch/xml'> <section name='configuration'> <configuration name='sofia.conf' description='RailsAdditionalConf'> <profile name='external'> <gateways> <gateway name="freeswitch2"> <param name="username" value="1007"/> <param name="realm" value="192.168.0.56:5061"/> <param name="password" value="xxxx"/> <param name="proxy" value="192.168.0.56"/> <param name="expire-seconds" value="30"/> <param name="register" value="true"/> <param name="register-transport" value="tls"/> <param name="retry-seconds" value="30"/> </gateway> </gateways> </profile> </configuration> </section> </document> Does anybody have a correct XML answer for a gateway and can post it? Best regards Peter

Call Recording
by Jerry Richards 18 Feb '11

18 Feb '11

Does the *2 DTMF method still work for recording calls? I recall this working before without needing to make changes to the dialplan XML, but right now it does not appear to work on the Sep 20 Freeswitch trunk. Thanks, Jerry

Doxygen help
by Yossi Neiman 08 Feb '11

08 Feb '11

I am not sure how many folks make use of the Doxygen documentation. I know I do all the time. I find that it provides a nice conceptual view of FreeSWITCH's API, which can make it very easy to find the functions and data types needed for writing modules for FreeSWITCH. A person by the name of Mohammad Shahzad (apologies if I misspelled it) started to do a lot of work on revamping the Doxygen configuration for FreeSWITCH a few months back. The problem with the work that he did was that he used Doxygen 1.6.x specific configuration parameters that are not understood by the Doxygen 1.4.x tree (which is what we currently use in FreeSWITCH) or even the 1.5.x tree which is what is in Slackware. In my discussions with Michael Collins we have decided that it might not hurt to go ahead and move the Doxygen version forward to match the 1.6.x tree. We are looking for somebody who has interest in working with the Doxygen configuration to continue the work that Mohammad had started and to help the project out. If you are such a person, please contact me off-list and I can provide further information. Thanks! Yossi Neiman
