Multiconference with g729 users only without transcoding
by Lluís Riera 16 Mar '11

16 Mar '11

Hi, I would like to know if is there a configuration in freeswitch to allow multiconferencing for g729 users but without transcoding? It seems that all users are converted to L16 and it's not possible to have passthrough mode in conference rooms. Best Regards, Lluís

Memory leak
by Pete Kelly 16 Mar '11

16 Mar '11

Hi We are using Freeswitch (from git sources) in a production environment to handle an IVR system using a simple set of dialplans and lua scripts. OpenSIPS 1.6 and mysql are also installed and running as part of the same IVR application. However over time (approx 1 week) the memory usage of Freeswitch increases, eventually creeping into swap space forcing us to restart Freeswitch. The IVR handles approx 40 concurrent calls constantly, and we have instances of the IVR running on a 32bit Etch and 64bit Lenny boxes - both exhibit the same issue. We have also tried the Sangoma freeswitch branch in case that contained any fixes, however we see the same issues. Can anybody advise if this is a known issue with Freeswitch? Is it a memory leak or is it possible to limit the amount of memory Freeswitch will use, forcing it to garbage collect when it reaches the limit? Any advice on where to look/debug next would be appreciated. Thanks Pete

probem with configuring DIDs
by Prime 16 Mar '11

16 Mar '11

Hey! This most likely is a newb mistake but I'm stuck at the moment. Recently I had to add another provider to FS to handle incoming calls. And now I have a problem with calling my new provider's DID number on my FS. I looked at FS logs. Usually FS log says something like this " [INFO] mod_dialplan_xml.c:418 Processing caller_number->My_DID in context public" and then routes DID number to local extension, but now I see something like this " [INFO] mod_dialplan_xml.c:418 Processing caller_number->caller_number in context public ". Why new numbers does not match the regex? The number are configured exactly as old ones. Thanks in advance Best regards

English NZ or English UK Prompt Set Recording
by Campbell Steven 16 Mar '11

16 Mar '11

Hi, I'm trying to get a group of people together to contribute money towards recording a standard set of New Zealand English prompts for FreeSWITCH. I'd like to get a New Zealand set done, but if there isn't enough interest I'd settle for a UK set and I'd have to take guidance on companies who could do that since I'm based in NZ. Anyway, let me know if you are interested in contributing money to a prompt set (either UK or NZ), that would be given back to the FreeSWITCH project. Thanks Campbell

Multi tenant and BLF
by Aloysius Lloyd 15 Mar '11

15 Mar '11

Hi All, I could not make the BLF working in multi tenant environment. Any help is appreciated. Discussion with BKW, he suggest to use multiple profiles. But if I want to use this box for x number of tenants then I need to setup x no of profiles. I like to use one profile for all my tenants. Multi tenant settings works for months without any issue. Here is my lab setup *compa.mydomain.com* Ext 201 - Cisco 504G + SPA500S Expansion Module - BLF 202,203 Ext 202 -SPA942 Ext 203 -SPA942 *BLF : Not working reliably .* *compb.mydomain.com* Ext 201 - Aastra 57i and Topkeys Configured for BLF 202,203 Ext 202 - Aastra 6731i Ext 203 - Aastra 6731 *BLF: working for couple of hours then completely stop working. A reboot of the phone required* *internal profile - The following lines comments*    --- Any help is appreciated how to make it work with single profile Thanks Lloyd

Uncovering spoken phrases in *encrypted* VoIP conversations
by EdPimentl 15 Mar '11

15 Mar '11

New recent study at *(Johns Hopkins / UNC)* says it can *Uncover spoken phrases in *encrypted* VoIP conversations * *(Johns Hopkins / UNC) ACM paper* We evaluate our techniques on a standard speech recognition corpus containing over 2,000 phonetically rich phrases spoken by 630 distinct speakers from across the continental United States. Our results indicate that we can identify phrases within encrypted calls with an average accuracy of 50%, and with accuracy greater than 90% for some phrases. Clearly, such an attack calls into question the efficacy of current VoIP encryption standards.
