putting files onto files.freeswitch.org?
by david varnes 08 Jan '10

Hi, First post here -- firstly thanks for a fantastic project/product. I have a java esl client implementation in my contrib/dvarnes and have just posted an announcement to users list. 2 questions: * In case there is any interest, and seeing as how many java users would prefer a binary jar to incorporate in a project, is there any process/rules about putting files onto files.freeswitch.org ? I would propose to put a snapshot jar file up for starters and see if there is any feedback. A release could follow. * Is there any way to generate a full set of events from FS to test the inbound ESL client with ? ie do you have some magic incantation that makes FS spit out a set of events ? thanks davidv

LuaSofia is a Lua binding of Sofia-Sip library (off-topic)
by Paulo Pizarro 07 Jan '10

07 Jan '10

Hi all, We like to present to all Sofia SIP developers a Lua bind to Sofia SIP, Luasofia. The objective of this project is to be able to use Sofia on a more high level language, Lua was chosen because of its easy integration with C, a lot of our projects are starting to use Lua integrated with C to make development and maintenance easier and faster, because of that we wanted to have a good SIP library to use in Lua, the decision was to make a bind to the already mature Sofia library. The bind is far from being complete, we only bonded the code that we need right now, there's a lot of work to do. We expect that the project will be useful, so a lot of documentation was made to help someone who wants to bind more Sofia code. There is good documentation on how to use it too. To develop we used git to make version control, and we hosted the project at github: http://github.com/ppizarro/luasofia The wiki is at github too: http://wiki.github.com/ppizarro/luasofia We hope Luasofia can be useful to a lot of people, and eventually we get some help making it better and more complete. Best regards, Luasofia team

Need some explainations about method switch_core_session_run(switch_core_session_t *session) in switch_core_state_machine.c
by Alex To 06 Jan '10

Hi, First of all, pardon my English. English isnt my native language J. I am reading the method switch_core_session_run(switch_core_session_t *session) and I would be really appreciated if someone could shed some light on how the method works. Below is the logic according to my understanding: 1. LINE 303: while ((state = switch_channel_get_state(session->channel)) != CS_DESTROY) ð if state is CS_DESTROY return and do nothing ? 2. Inside if (state != switch_channel_get_running_state(session->channel) || state >= CS_HANGUP) { } a. LINE 308: state != switch_channel_get_running_state(session->channel) || state >= CS_HANGUP ð to check if channel->state and channel->running_state not equal. This is to avoid running the STATE_MACRO multiple times. However I dont understand why do we need (state >= CS_HANGUP) ?. b. Inside STATE_MACRO code block i. LINE 229: midstate = state ð to save the current state. ii. LINE 231: if (!driver_state_handler->on_##__STATE || (driver_state_handler->on_##__STATE(session) == SWITCH_STATUS_SUCCESS) ð to check either endpoint_interface->state_handler is NULL or return SWITCH_STATUS_SUCCESS so it will continue to execute handlers in session->channel, runtime.state_handlers and core standard state handlers. It means if the condition is not true, channel->state_handlers, runtime.state_handlers and core standard state handlers will NOT be executed at all ? iii. LINE 246: if (!proceed) global_proceed = 0; ð If something wrong in the previous while loop, do not run core standard state handlers ? iv. LINE 247: proceed = 1; LINE 248: while (do_extra_handlers && proceed && (application_state_handler = switch_core_get_state_handler(index++)) != 0) { } ð Since we set proceed = 1, do we still need (&& proceed) inside the condition in while loop ? v. LINE 260: if (!proceed || midstate != switch_channel_get_state(session->channel)) global_proceed = 0; ð If not proceed or the channel state has changed by some of the state handlers executed earlier, do not execute core standard state handler ? vi. LINE 266: while (silly) ð silly is never changed, does it mean we could go into an endless while loop ? Sorry for the long email and some questions are probably dumb but I am trying to understand about FreeSwitch, especially the core and the core state machine. If it is documented somewhere about the workflow happening inside FreeSwitch, please enlighten me as what I am doing now is to read the code line by line and figure out which may not be the most efficient . Thank you for reading this Regards Alex To

FS doesn't update rtp port when sdp changed in 200OK response for invite message.
by Lei Tang 30 Dec '09

30 Dec '09

Merry Christmas everyone! I'm using FS 1.0.5pre9, I think there is a bug in mod_sofia when SDP changed in 200 OK response for INVITE message, the scenario is : A(FreeSwitch) B ------INVITE -------> <----100 Tring-------- <----180 Ring -------- with sdp m=audio 55066 RTP/AVP 0 120 c=IN IP4 10.36.143.76 <----UPDATE ------- with sdp m=audio 45486 RTP/AVP 0 120 c=IN IP4 10.36.143.76 -----200 OK ------> response for UPDATE message <---- 200 OK-------- response for INVITE message, with sdp m=audio 45486 RTP/AVP 0 120 c=IN IP4 10.36.143.76 --------ACK ---------> The problem is, B changed the rtp port in UPDATE message and "200 OK" response message, but FS didn't do update, so it still send and receive data from port 55066. I read the mod_sofia source code and debug log, I found that when get 200OK response ,mod_sofia should update rtp session when sdp information is different of the the pre sdp received in 180 ring response, I'm using proxy_media mode, and I think there is the same problem in normal mode. here is the outbound channel state change log ============================== entering state [received][100] entering state [calling][0] entering state [proceeding][180] entering state [proceeding][200] entering state [completing][200] entering state [ready][200] entering state [completed][200] entering state [ready][200] The problem is in state [proceeding][200], The code is as follow: sofia.c line 3876 if (switch_channel_test_flag(channel, CF_PROXY_MEDIA)) { if (sofia_glue_activate_rtp(tech_pvt, 0) != SWITCH_STATUS_SUCCESS) { goto done; } } Since the rtp session is initialized when 180 RING response received, sofia_glue_activate_rtp will return SWITCH_STATUS_SUCCESS without change any thing, So, I think the code should be as follow 3876 if (switch_channel_test_flag(channel, CF_PROXY_MEDIA)) { 3877 if (tech_pvt->rtp_session && !is_dup_sdp){ 3878 sofia_set_flag_locked(tech_pvt, TFLAG_REINVITE); 3879 if (sofia_glue_tech_proxy_remote_addr(tech_pvt) != SWITCH_STATUS_SUCCESS || sofia_glue_activate_rtp(tec h_pvt, 0) != SWITCH_STATUS_SUCCESS) { 3880 sofia_clear_flag_locked(tech_pvt, TFLAG_REINVITE); 3881 goto done; 3882 } 3883 sofia_clear_flag_locked(tech_pvt, TFLAG_REINVITE); 3884 }else{ 3885 if (sofia_glue_activate_rtp(tech_pvt, 0) != SWITCH_STATUS_SUCCESS) { 3886 goto done; 3887 } 3888 } 3889 } When get 200OK reponse and sdp is changed, we should update remote port and set reinvite flag before call sofia_glue_activate_rtp. Because I'm not so familiy with sofia and mod_sofia's source code, this code is only for PROXY MEDIA mode and doesn't check for codec changed.(in my scenario, only the remote port and ip are changed). Could some fs dev check this problem, and give a offical patch? BTW, I guess maybe mod_sofia is just ignore UPDATE message too. (just ignore it if I was wrong) Best Regards -- Lei.Tang lei.tlfly(a)gmail.com
