Why does both core.db and sofia_reg_internal.db have registrations tables?
by Jerry Richards 30 May '12

30 May '12

Just curious why core.db and sofia_reg_internal.db have registrations tables? Is this redundant? Thanks, Jerry From: Jerry Richards Sent: Wednesday, May 23, 2012 10:06 AM To: 'FreeSWITCH Users Help' Subject: Channel Variable To Disable Processing of 2833 DTMF Messages? Is there a channel variable to disable/ignore 2833 DTMF messages that are going from the internal network toward the PRI? I have a scenario where I am getting both inband and out-of-band DTMF (i.e. double DTMF digits). This happens when a call comes in through the PRI and routes back out the PRI. Inband DTMF coming from the caller is converted to out-of-band 2833 internally, so when the audio is routed back out the PRI, it contains both the inband DTMF and the 2833 conversion. In some cases, we don't want to use disable_dtmf, since we may need to detect inband DTMF in FreeSwitch. Thanks, Jerry

FreeSWITCH Weekly News and Notes
by Michael Collins 30 May '12

30 May '12

Happy Tuesday to all. We hope you enjoyed your holiday weekend. We've had a steady stream of presentations on the FreeSWITCH conference call over the past month. Ken Rice has graciously done two presentations on how to create a dialplan module in C, including a fully functional example module. This code is extremely helpful not just in understanding how to write a dialplan module but in writing any module that exposes new dialplan applications or command line APIs. This week we will take a break from the formal presentations and have an open discussion on any topics of interest to the community. Our ClueCon plans are gearing up as well. We are pleased to announce that Plivo, Inc. is a brand new silver sponsor for this year's event. Plivo<http://www.plivo.org?cc12-0529>is an open-source framework for developing Web-based solutions with FreeSWITCH. We are also happy to report that the Illinois Institute of Technology (IIT) is again with us a media sponsor. IIT holds the annual Real-Time Communications conference and expo <http://www.rtc-conference.com?cc12-0529>where academia and industry meet to discuss various aspects of global telecommunications. We invite you to visit our sponsors' Web sites to learn more about what they have to offer. As a reminder, ClueCon still has openings for sponsors and speakers. Please contact us via email or at the phone number below if you have any questions. Visit the registration<http://www.cluecon.com/register?cc12-0529>page to get signed up and be sure to book your room at the Wyndham <http://www.cluecon.com/hotels?cc12-0529>. (And don't forget that the Wyndham will shortly be renamed to the Hyatt Chicago Miracle Mile.) We look forward to meeting everyone in person this August! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE cc12-0529

request SDP in 200 OK
by B.Tietz＠pinguin.ag 30 May '12

30 May '12

Hi list, I want to receive faxes with T.38 and spandsp (app spandsp). The INVITES for the calls come with or without SDP-headers. If the SDP-header is in the INVITE to freeswitch, Freeswitch can receive the fax without problem. But if FS gets an INVITE without SDP it can not receive the call and ends with error code 'MANDATORY_IE_MISSING', because FS doesn't send an SDP-offer in the 200 OK message. How can I achieve this? Is it late-negotiation? Benjamin

A couple of short questions on mod_sms: Has anyone done any work with using xml_curl to get the chatplan? If that isn't available, how about ESL OUTBOUND in the chatplan? Much thanks..... Tim

Gateway failover with LUA
by Muhammad Naseer Bhatti 29 May '12

29 May '12

Hi, I am trying to implement a gateway failover functionality with lua. Right now I am using limit and using hash backend to limit number of channels to each gateway. Since I am forwarding all calls with a default dialplan which is sending all calls to application lua and the bridge is done outside lua setting all the necessary vars. The idea is if all channels of first gateway are occupied, send the call to second gateway in the list and so on. Any idea how to implement this with lua? Can not seem to find the logic. If I query with limit_status it is going to be a query on every call. In a high call volume scenario, I don't think this would be really a good choice. Any ideas, thoughts? Thanks.
