t.38 in newer fs versions - t38-passthru
by Christian Löschenkohl 21 Jun '10

21 Jun '10

hello has anybody tried the config parameter t38-passthru in a sip profile? our fs server core dumped today after i did set the option an did a reladxml + a profile rescan does this option bring back the old behavior that the proxy mode provided? the actual behavior (actual git from 17.06.2010) is not useable. t.38 isn't passed through without modification and fax sending fails almost every time. in e.g. version 1.0.6 t.38 in proxy mode worked 100% reliable br -- Ing.

mod_limit / db / hash changes - If you update action is required
by Rupa Schomaker 21 Jun '10

21 Jun '10

If you've been paying attention to the conf call or irc you'll know this change was coming. I've committed a significant change to how limits are managed in FreeSWITCH. This change is NOT backwards compatible. It requires one to: 0) git pull (of course) 1) rerun ./configure to generate new Makefiles for new modules 2) edit modules.conf, remove mod_limit and add mod_db and mod_hash 3) modify conf/autoload_configs/modules.conf.xml, remove mod_limit and add mod_db and mod_hash 4) create/edit conf/autoload_configs/db.conf.xml if using ODBC In your dialplan, anywhere you are using limit, you need to add db to the data line. Anywhere you are using limit_hash you need to remove _hash from application and add hash to the front of the data line. Same pattern applies to any API usage of limit you may be using. Read the wiki at: http://wiki.freeswitch.org/wiki/Limit for documentation on limit. Ok, why the change? limit has been moved into core with support for pluggable backend limit providers. This allows one to develop limit backends relatively easily and provides a more structured interface to these different limit backends. Expect to see backends provided by more than just db and hash. It also always bothered me that db and hash were part of the mod_limit module. They are not standalone and provide functionality specific to themselves. I've updated the wiki with documentation. I'll continue to update the wiki as necessary, feel free to do so yourself if there is something unclear or missing. -- -Rupa

Start/stop recording controls and multiple recordings of a single conference.
by M. Ranganathan 20 Jun '10

20 Jun '10

Hello, I have a couple of questions about the behavior of conference recording: 1. In Looking at the semantics of norecord as stated in, http://wiki.freeswitch.org/wiki/Mod_conference it is not clear to me whether or not it is possible to start/stop/restart recording of an ongoing conference. Any clarifications would be appreciated. 2. Can you have multiple recordings for a given conference? i.e. conference foo record /tmp/recording1.wav and conference foo record /tmp/recording2.wav at the same time for a single ongoing conference. Thank you in advance for any help. Regards, Ranga -- M. Ranganathan

check if transcoding is needed
by Pete Kay 20 Jun '10

20 Jun '10

Hi, Is there anyway to detect/check if codec transcoding is needed? What I would like to do is to set "bypass_media=true" if no transcoding is needed. Any suggestion on how / when should bypass_media be turned on/off? thanks, P

Mobile callback + DISA
by FreeSWITCH-Users 20 Jun '10

20 Jun '10

Hi all, I am new to FS but have been working with * for a while.. I have * setup for callback+DISA used by family for cellular minutes. Have been looking at FS this past month or so as I'd like to setup FS on my router with DD-WRT + FS. Presently I have figured out how to setup disa.js for DISA on my cell BUT I can't seem to find anything out on the web about configuring callback. Has anyone figured out how to setup callback+DISA? Any help is appreciated, links or any ideas would help me over this hurdle. Cheers, S.

mod_lcr update - read if you use custom_sql
by Rupa Schomaker 20 Jun '10

20 Jun '10

mod_lcr has been updated. commit log: mod_lcr update. MODAPP-340, MODAPP-355 arbitrary b-leg vars, limit support, lcr/ endpoint custom_sql now is field based rather than position based NOTE: custom_sql is incompat with prior version arbitrary b-leg vars enable integration with mod_nibblebill. Wiki has been updated: http://wiki.freeswitch.org/wiki/Mod_lcr This change is backwards compatible EXCEPT if you use custom_sql. If you use custom_sql you must update your sql to use field aliases (SQL : AS). The module no longer uses position in the custom sql for fields. So, if you use custom_sql, reread: http://wiki.freeswitch.org/wiki/Mod_lcr#Custom_SQL Ok, I'm done breaking things for the day. :) -- -Rupa

continue_on_fail and hangup_after_bridge with transfer

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})$|^\+([0-9]{11})$)$"> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="failure_causes=TIMEOUT,NO_ROUTE_DESTINATION"/> <action application="set" data="continue_on_fail=NORMAL_TEMPORARY_FAILURE,TIMEOUT,NO_ROUTE_DESTINATION"/> <action application="set" data="auto_hunt=true"/> <action application="set" data="real_dialed_number=7777777"/> </condition> <condition field="destination_number" expression="^(79|89)(\d{9})$" 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 ilti gateway to the next. if not available all the gateway to go to the extension transfer.

Build the mod_unimrcp module
by Thangappan.M 19 Jun '10

19 Jun '10

Dear all, I am in the process of developing IVR. So just planned to convert my application to handle the TTS voice engine which is supported by FreeSWITCH. Got the mod_unimrcp module which is used to recognize the speech and synthesize the text to voice. For building the mod_unimrcp modules done the following steps. Uncomment the mod_unimrcp line in the modules.conf file in the FreeSWITCH source Given make mod_unimrcp-install command. In modules.conf.xml uncomment the <load modue="mod_unimrcp"/> Configured the following dial plan <extension name="unimrcp"> <condition field="destination_number" expression="^4922$"> <action application="answer"/> <action application="set" data="tts_engine=unimrcp:nuance5-mrcp1"/> <action application="set" data="tts_voice=awb"/> <action application="speak" data="This is our Text to speech on FreeSWITCH"/> --> <action application="sleep" data="500"/> </condition> </extension> While making the call to 4922 got the following error in the FreeSWITCH console.
