Question on sofia_glue_execute_sql_callback()
by Jerry Richards 30 Jun '10

30 Jun '10

I have a couple of questions regarding to sofia_glue_execute_sql_callback(). 1) If a given sql select statement results in a matching entry in the .db file, then the callback function should be invoked. True? 2) Does the following select statement query the db/sofia_reg_internal.db database? select sip_registrations.sip_user, '192.168.72.38', sip_registrations.status, sip_registrations.rpid,'', sip_dialogs.uuid, sip_dialogs.state, sip_dialogs.direction, sip_dialogs.sip_to_user, sip_dialogs.sip_to_host, sip_presence.status,sip_presence.rpid from sip_registrations left join sip_dialogs on (sip_dialogs.sip_from_user = sip_registrations.sip_user and sip_dialogs.sip_from_host = sip_registrations.sip_host) left join sip_presence on (sip_registrations.sip_user=sip_presence.sip_user and sip_registrations.sip_host=sip_presence.sip_host and sip_registrations.profile_name= sip_presence.profile_name) where sip_registrations.sip_user='5381' and (sip_registrations.sip_host='192.168.72.38' or sip_registrations.presence_hosts like '%192.168.72.38%') The reason I'm asking is because I don't see the callback function getting called, but if I run the query in a separate sqlite3 session, it does find a matching entry in the db/sofia_reg_internal.db. Do you know why the callback function is not getting invoked? Best Regards, Jerry

doubt about fax via audio
by Eduardo Nunes Pereira 30 Jun '10

30 Jun '10

I did some testing with FreeSwitch, using my endpoint, and passing audio, everything is working, but when I move my fax using the fax hardware resources lost quality, and sometimes does not send at all, may be some function or flag that I not used in my andpoint?

continue_on_fail and hangup_after_bridge with transfer
by Vladimir Elizarov 30 Jun '10

30 Jun '10

I'm trying to make a dialplan: <extension name="Long Dial"> <condition field="destination_number" expression="^(^([0-9]{10})$|^([0-9]{11})$|^([0-9]{12})$|^\+([0-9]{11})$)$"> <action application="set" data="hangup_after_bridge=true"/> <action application="set"data="continue_on_fail=NO_ROUTE_DESTINATION"/> <action application="set" data="real_dialed_number=7777777"/> </condition> <condition field="destination_number" expression="^(79|89)(\d{9})$" break="on-true"> <action application="set" data="dtmf=WWWWWWWWWWWWWWWWWWWWW111222#WWWWWW89$2#@100"/> <action application="bridge" data="sofia/gateway/gw1/89$2|sofia/gateway/gw2/89$2|sofia/gateway/gw3/89$2"/> <action application="transfer" data="to_card"/> </condition> </extension> <extension name="to_card"> <condition field="destination_number" expression="^to_card$"> <action application="bridge" data="{execute_on_answer=send_dtmf\s${dtmf}}sofia/internal/${real_dialed_number}@192.168.50.53:5061"/> </condition> </extension> The logic of his work: if unavailable gateway to the next. if not available all the gateway to go to the extension transfer. A problem in If we get a code busy here, it is not satisfied hangup_after_bridge. The call goes to the transfer. Why is this so? trace: http://pastebin.freeswitch.org/13244 -- Best regards, Vladimir Elizarov

Re: [Freeswitch-dev] Newbie question on switch_event_dup() with a code snippet
by Paul Li 30 Jun '10

30 Jun '10

I guess you were assuming I would pass the event clone (pointer) to the core API (such as switch_event_fire), so that I would not need to free the clone pointer. I guess I still need to destroy it in the following scenario: static void my_event_handler(switch_event_t *event) { switch_event_t *clone = NULL; if (switch_event_dup(&clone, event) == SWITCH_STATUS_SUCCESS) { /* use clone in my extended context */ switch_event_destroy(&clone); } } > Anthony Minessale > Tue Jun 29 12:30:52 PDT 2010 > > yes any functions that take pointers to pointers and leave you with null > will indicate you don't have to do anything. >

Newbie question on switch_event_dup() and memory alloc/free in general
by Paul Li 29 Jun '10

29 Jun '10

A lot of FreeSwitch core APIs, such as switch_event_dup(switch_event_t **event, switch_event_t *todup), returns a pointer to an allocated memory chunk, should the caller always releases that memory chunk by calling a proper API, such as switch_event_destroy(switch_event_t **event)? I could not find any documentation to detail the general rule regarding memory allocation/free when using the core APIs. Thank you for your attention!

Hello, Is there a way to include the session uuid in mod_spandsp_fax logs? I'm getting something like: 27293b76-839e-11df-a59a-df3daa5a8da2 2010-06-29 18:49:00.494082 [DEBUG] mod_spandsp_fax.c:328 remote vendor: 27293b76-839e-11df-a59a-df3daa5a8da2 2010-06-29 18:49:00.494082 [DEBUG] mod_spandsp_fax.c:329 remote model: 27293b76-839e-11df-a59a-df3daa5a8da2 2010-06-29 18:49:00.494082 [DEBUG] mod_spandsp_fax.c:331 ============================================================================== 2010-06-29 18:49:00.494082 [DEBUG] mod_spandsp_fax.c:271 FLOW T.30 Changing from state 22 to 32 2010-06-29 18:49:00.494082 [DEBUG] mod_spandsp_fax.c:271 FLOW T.30 Changing from phase T30_PHASE_D_RX to T30_PHASE_CALL_FINISHED 2010-06-29 18:49:00.494082 [DEBUG] mod_spandsp_fax.c:271 FLOW T.38T Set rx type 8 2010-06-29 18:49:00.494082 [DEBUG] mod_spandsp_fax.c:271 FLOW T.38T Set tx type 8 2010-06-29 18:49:00.494082 [DEBUG] mod_spandsp_fax.c:271 FLOW T.38T FAX exchange complete Where cannot filter the session using the sessionid. I took a quick look into the source code but seen that would need to pass the session somehow to spanfax_log_message. Any idea how to change that? Regards, Tamas

Merging A Law Audio data
by Achim Stamm 29 Jun '10

29 Jun '10

Hello! I have following problem: I get 160 Bytes Audio data (Format PCM A Law) from a Free Switch Session and save the data in a byte vector. At same time i get 160 Bytes Audio data (Format PCM A Law) from an external program and save the data in a byte vector. I want to merge the two audio data like a conference FreeSwitch Session mixed them. Can I use a Free Switch audio - Merge (C ++) Function ? How does Free Switch merge Audio Data in Conference mode ? regards Achim Stamm -- Achim Stamm, Dipl.-Inform.

Doubt on bridge programatically
by Juan Antonio Ibañez Santorum 28 Jun '10

28 Jun '10

Hello! I am working on a module having this doubt: Once a call reachs to dialplan I call my app and I don't know which is the best way (if more than one exits) to bridge that call to an onbound provider controlling failed connections to try with a failure trunk. Is there any way to get call connection status (BUSY, CONGESTION...) from code? Is necessary to use events or may it be obtained as result of bridge function? Regards

odbc连接过多的问题
by 王洪永 28 Jun '10

28 Jun '10

在测试FREEESWITCH 1.0.19版本时候发现一个问题，会引起odbc过多连接，导致无法创建新连接问题。查找代码发现应该是下面的函数没有去掉连接的使用标志。 SWITCH_DECLARE(void) switch_cache_db_release_db_handle(switch_cache_db_handle_t ** dbh) { if(dbh && *dbh) { switch_clear_flag(*dbh, CDF_INUSE); //去掉使用状态标志 switch_mutex_unlock((*dbh)->mutex); *dbh = NULL; } } 王洪永中企开源-IP通讯部 Mon, 28 Jun 2010 09:19:50 +0800
