Dear All, We have launched three new acoustic models for use with Vestec ASR: (1) Australian English, (2) Chinese Mandarin, and (3) Indian English. Vestec offers the best deal around for enabling sophisticated speech recognition with command-and-control type IVR applications. Our ASR supports SRGS grammar format, can be integrated using MRCP (v1 & v2) interface, offers high recognition accuracy, and costs a fraction of conventional speech engines. We offer the ASR in two versions according to vocabulary size: 500 items vocabulary and 2,500 items vocabulary, per recognition. A starter kit is available for $25 from Vestec webstore: http://www.vestec.com/products Please do not hesitate to contact me with any questions. We are looking forward to being of service.

Freeswitch Server getting down
by ovvenkat 03 Jun '11

03 Jun '11

Hi to all, I dont know whether this problem related to PRI line (OR) wanpipe driver ( OR ) PRI Card I use Linux fedora 13 and Sangoma A101 PRI card to handle incoming calls from E1 lines. Everything works fine for some time. After that, I could see cli debug output saying, all the channels are disconnected and then immediately it says that "signaling status changed to UP". After some time, freeswitch getting shutdown saying ftmod_wanpipe.c:967 [s1c31][1:16] Failed to read from sangoma device: No buffer space available (-65) I pastebin debug logs for the same. http://pastebin.freeswitch.org/16432 I am failed to identify the problem. Can you anyone guide me what is going wrong? Regards Venkatesan OV.

Transferring to a cell phone
by Yungwei Chen 03 Jun '11

03 Jun '11

Hi, I installed freeswitch from a recent snapshot on CentOS 5. I configured a gateway for my SIP provider in /usr/loca/freeswitch/conf/sip_profiles/external/my.xml, and I can make an outbound call to my cell phone using the following javascript snippet. var new_session = new Session("{ignore_early_media=true}sofia/gateway/sip_provider/1231231234"); Now I am trying to make a call from a land-line to a javascript application in freeswich, which plays a recording and then transfers the call to a cell phone. But transferring the call to a cell phone doesn't work for some reason. Here's how I transfer the call to a cell phone in javascript: session.execute("transfer", "{ignore_early_media=true}sofia/gateway/sip_provider/1231231234"); According to freeswitch.log, the problem seems to be that freeswitch cannot find a dialplan that matches the destiantion number, {ignore_early_media=true}sofia/gateway/sip_provider/1231231234. What am I missing here? Thanks.

Any way to limit the ability to create conference rooms on demand?
by André Rosowski 03 Jun '11

03 Jun '11

Hi there, I'm using Bigbluebutton (online conferencing) with Freeswitch so that users can call a number and then have to enter the "voicebridge" number to be put into a voice conference. The problem, however, is that if a user dialed the wrong "voicebridge" number he will be put into a new conference thus creating one on demand as stated in the describtion of "mod_conference". Is there any way to manually create conference rooms and make them static...not allowing for new conference "rooms" to be created on demand. default.xml in dialplan: <extension name="phone conference"> <condition field="destination_number" expression="^(SEND_TO_CONFERENCE)$"> <action application="conference" data="${pin}@wideband"/> </condition> </extension> Thanks for your help : ) Regards, Realdoe -- Omigos Labs UG (haftungsbeschränkt) - Meisenstraße 96 - 33607 Bielefeld Fon: +49 521 2997 200 - Fax: +49 521 2997 101 info(a)omigos.de - www.omigos.de Geschäftsführer: BSc André Rosowski, Benjamin Bittner, Julian Klima Registergericht: Amtsgericht Bielefeld - Registernummer: HRB 40255 USt-IdNr.: 305/5860/1585

ptime mismatch confusion
by Michael Gende 03 Jun '11

03 Jun '11

Hello, If you are a codec/ptime person, great. I've been "round and round" with the vendor on this and and not making much headway. We've an FS switch that has two numbers registered with our provider. That provider is, in turn, getting service from another gateway provider of their own. On our FS, one DID works with no issues and has for more than a year. They other recently started having ptime mismatch issues making it unusable. Tried Scrooge setting to no avail. For the daring (and merciful), here's FS output for a "bad" call and then a "good" one (just a little output from the start): 2011-06-02 14:12:06.756170 [DEBUG] switch_core_state_machine.c:397 (sofia/external/8151231234@xxx.xxx.xxx.xxx:5060<http://8154835414@208.94.159.10:5060/>) Running State Change CS_NEW 2011-06-02 14:12:06.756170 [DEBUG] sofia.c:3210 Channel sofia/external/ 8151231234@xxx.xxx.xxx.xxx:5060 <http://8154835414@208.94.159.10:5060/>entering state [received][100] 2011-06-02 14:12:06.756170 [DEBUG] sofia.c:3217 Remote SDP: v=0 o=Acme_UAS 0 1 IN IP4 xxx.xxx.xxx.xxx s=SIP Media Capabilities c=IN IP4 yyy.yyy.yyy.yyy t=0 0 m=audio 52024 RTP/AVP 0 18 101 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 *a=maxptime:30 * 2011-06-02 14:12:06.756170 [DEBUG] switch_core_state_machine.c:403 (sofia/external/8151231234@xxx.xxx.xxx.xxx:5060<http://8154835414@208.94.159.10:5060/>) State NEW 2011-06-02 14:12:06.756170 [DEBUG] sofia_glue.c:3081 *Audio Codec Compare [PCMU:0:8000:30]/[PCMU:0:8000:**20]* 2011-06-02 14:12:06.756170 [DEBUG] sofia_glue.c:3092 Bah HUMBUG!

Huh? For my part, I'd just like to FORCE a ptime of 20 in all cases, no matter the codec, for incoming calls, either DID. Tried, but so far, no go. A packet capture showed "bad" call coming in with ptime max of 30, we respond that 30 is OK but them re-invite with ptime set to 20, but it doesn't seem to "catch". On the good DID, they proffer ptime max of 30, we respond with ptime of 20 and life is good. Sorry to post again on this. I have put in some hours but still same results so far. Any suggestions much appreciated. Regards, Mike
