[Freeswitch-dev] nolocal exports from dial plan
by Dino Korah 25 Nov '10

25 Nov '10

Guys, When I export a variable as nolocal, is it intended to prefix "nolocal:" for that variable on A, when that appears in the CDR? Or is it a glitch? Ref: src/mod/applications/mod_dptools/mod_dptools.c line 889 Here if you check, the export seems to ignore the local variable altogether. I am quite new to freeswitch; any help much appreciated. Many thanks, "dk"

[Freeswitch-dev] FXS bridged on FXO ports and DTMF - Deja Vu
by Jeroen C. van Gelderen 13 Jul '10

13 Jul '10

Hi everybody, I have a problem that is very similar to a problem reported by François [1] except for the fact that my FXS and FXO ports are on a Xorcom Astribank device instead of a Sangoma. To quote François: "The problem is that each leg of the bridge is detecting the inband DTMF, and so [F]reeswitch sends each detected DTMF from one leg to the other, and so on and so forth (as each leg detects the DTMF again and again)" HIS words but evidenced by the MY log :) The snippet below has DTMF coming in on the FXS port (1:1) and bouncing between it and the FXO port (3:1). The ports are simply bridged together with "bridge(OpenZap/3/1/F)" or "bridge(OpenZap/3/1/w)" I'm running: FreeSWITCH version: 1.0.head (git-01c0c69 2010-06-08 16-22-21 -0500) dahdi: Version: SVN-trunk-r8762 Output of lsdahdi at end of message. ----8<----8<----8<----8<----8<----8<----8<---- [...] 2010-06-13 04:18:39.217256 [DEBUG] mod_openzap.c:721 queue DTMF [4] 2010-06-13 04:18:39.256255 [DEBUG] zap_io.c:2062 3:1 GENERATE DTMF [4] 2010-06-13 04:18:39.397253 [DEBUG] mod_openzap.c:721 queue DTMF [4] 2010-06-13 04:18:39.439252 [DEBUG] mod_openzap.c:780 Dropping frame!

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 09:18:52 +0800

[Freeswitch-dev] [freeswitch-dev] libfreeswitch cleanup
by Paulo Vicentini 30 Jun '10

30 Jun '10

Hi, I am embedding libfreeswitch to my application's process space and I need to "init" and "destroy" freeswitch while running my process. I face problems after calling switch_core_destroy and when my business logic demands I call switch_core_init_and_modload to work with libfreeswitch (again) It seems that struct switch_runtime runtime is not cleared aproprietaly when destroying the core. I made some tests clearing runtime struct but still getting segfaults on apr_queue_trypush (trying to find out the issue) Can you please help me out with this issue? Thanks

[Freeswitch-dev] 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

A problem in If we get a code busy here, it is not satisfied hangup_after_bridge. The call goes to the transfer.
