[Freeswitch-dev] Issue while creating a session for an incoming call in managed application
by Papineni, Suneel 02 Jul '12

Hi, I am having a third party VoIP client which exposes API in .NET to communicate with my application. I want to use this client as an endpoint in Freeswitch (like how it is implemented in "mod_skypopen" module), so that calls coming to this client can be handled at Freeswitch and (if required) bridge calls to clients connected to Freeswitch. To implement this, I have written a managed module in which "ILoadNotificationPlugin" is implemented where config (client's interface config) is loaded. When there is an incoming call (ringing state) to the client, I get handle in managed module and trying to establish a session at freeswitch. While doing this I am getting exception as "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." Here is the code that I am using... Could someone guide me if I am doing this correctly. Note: I am following "mod_skypopen" as an example... public static int new_inbound_channel(private_object pobject) { SWIGTYPE_p_switch_core_session session = null; SWIGTYPE_p_switch_channel channel = null; switch_endpoint_interface intf = new switch_endpoint_interface(); intf.interface_name = "NET_interface"; intf.io_routines = io_routines; intf.state_handler = state_handlers; freeswitch.switch_core_set_globals(); Api fsApi = new Api(); String uuid = fsApi.ExecuteString("create_uuid"); try { session = freeswitch.switch_core_session_request_uuid(intf, switch_call_direction_t.SWITCH_CALL_DIRECTION_INBOUND, 0, null, uuid); //I am getting the above issue here.... if (session != null) { freeswitch.switch_core_session_add_stream(session, null); channel = freeswitch.switch_core_session_get_channel(session); if (channel == null) { freeswitch.switch_core_session_destroy_state(session); return 0; } freeswitch.switch_channel_set_variable_name_printf(channel, "waste", "false"); pobject.caller_profile = freeswitch.switch_caller_profile_new(freeswitch.switch_core_session_get_pool(session), "NETClient", "dialplan", "callid_name", "callid_number", null, null, null, null, "mod_netclient", "context", "destination"); if (pobject.caller_profile != null) { freeswitch.switch_channel_set_name(channel, "name"); freeswitch.switch_channel_set_caller_profile(channel, pobject.caller_profile); } freeswitch.switch_channel_set_state_flag(channel, switch_channel_flag_t.CF_GEN_RINGBACK); switch_status_t session_status = freeswitch.switch_core_session_thread_launch(session); if (session_status != switch_status_t.SWITCH_STATUS_SUCCESS) { freeswitch.switch_core_session_destroy_state(session); return 0; } } } catch (Exception exp) { string expstring = exp.Message; } return 0; } Thanks & Regards Suneel

Hi, i am not sure, if it was an update with latest debian or some changes in latest trunk version of Freeswitch, but since today i am getting the following error when trying to build debian packages: I am using the latest, clean GIT-Version of Freeswitch.

[Freeswitch-dev] FreeSWITCH Weekly News and Notes
by Michael Collins 02 Jul '12

02 Jul '12

Welcome to July! We hope the leap second didn't crash any of your servers. Some folks were not so fortunate<http://www.bbc.co.uk/news/technology-18672173> . On last week's conference call we had an open discussion on topics chosen by members of the community. One topic that got a fair amount of traction was how to address NAT when FreeSWITCH has a public IP address and the clients themselves are behind NAT. Dave Kompel shared his strategy of using "aggressive-nat-detection" on the SIP profile and then optionally setting "NDLB-connectile-dysfunction" for the directory entry. We also discussed other topics like IPv6 and using FreeSWITCH in the cloud with Amazon. The audio is available here<http://torrents.freeswitch.org/conf_call_2012-06-27.torrent?cc12-0702> . Darren Schreiber's company, 2600hz, made a very interesting announcement<http://www.prnewswire.com/news-releases/2600hz-launches-new-service-kazoo-b…>regarding "Kazoo BETA." This new cloud-based PBX solution uses a lot of open source software under the hood, including FreeSWITCH. Stay tuned for a more in-depth discussion with Darren about this new platform. On the ClueCon front we are happy to report that many have taken advantage of the fact that they can get 2^4 tickets (i.e. 16 tickets) for the drawings at ClueCon 2012. The bits will shift at the end of the day tomorrow, July 3, so don't delay! You can register quickly and easily here<http://www.cluecon.com/register?cc12-0702>on the ClueCon site. After July 3rd registrants will receive 2^3 or 8 tickets. Don't delay - we are giving away a total of ten 7" Android tablets among many other prizes supplied by our sponsors<http://www.cluecon.com/sponsors?cc12-0702> . Only 35 days until ClueCon 2012! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE cc12-0702
