Proxy Media for IVR bridged calls
by Rogelio Perez 08 Jun '10

08 Jun '10

Hi all, I have configured my internal profile to proxy all media, so I can use the g.729 codec for calls between extensions, even when they are behind NAT. Now I have a DID pointing to my FS instance, which triggers a standard IVR with a greeting message and a directory. Then someone calls the IVR and dial any extension, and when the call is answered it fails with error: error mod_g729.c:102 This codec is only usable in passthrough mode! I believe that the IVR bridge is not using proxy media, and that's why the call fails. My question is: how do I force proxy media for IVR bridged calls? Thanks! Rogelio

Convert DTMF Between Inband and Out-of-band
by Code Ghar 08 Jun '10

08 Jun '10

I have come across a scenario: server (proprietary software, etc. -- let's call it S1) receives a new call from ingress carrier (let's call it IN1), does its thing, and connects to egress carrier (let's call it OUT1). Once call is answered by egress end, it does a re-invite between ingress and egress carriers. This re-invite keeps the server (S1) in signaling path but makes the ingress (IN1) and egress (OUT1) carriers send RTP to each other directly. Initial negotiation does DTMF using RFC2833 (out-of-band) but still in the media stream. The result is that after re-invite if IN1 sends a DTMF event meant for S1, it actually goes to OUT1 instead. One solution is to use SIP INFO for DTMF. Since S1 is in signaling path it will receive all SIP INFO packets and do what with them what needs to be done. And this is where my question arises. Let's say our FS server is IN1. It also has an ingress and egress carrier. In this case ingress could be anyone (let's call it INORIG) but egress is S1. If IN1 receives DTMF event using RFC2833 but needs to send the event to S1 using SIP INFO, can it be done in FreeSWITCH? In effect, can FS do conversion between RFC2833 and SIP INFO? And if it can, can this conversion be used for only some gateways and not all? Thanks.

if I understand multiple conditions in an extension mean "if cond1 AND cond2 THEN condLAST" ? if yes, how to use condtions as IF cond1 OR cond2 the condLAST ?

vars scope in dialplan
by Madovsky 08 Jun '10

08 Jun '10

example : <extension name="blabla"> <condition> <action application="set" data="test=cake"/> </condition> <condition field="${test}" expression="^(cake)$"> <action application="set" data="prfx=00"/> </condition> <condition field="${sip_to_uri}" expression="^(1\d{10,15})@$${domain}$"> <action application="set" data="getPrfx=${prfx}"/> </condition> </extension> but ${prfx} is empty. I'm almost sure I didn't understand FS vars scope yet.... Thanks Franck

mod_conference – moderator flag & xml_list
by David Swardstrom 07 Jun '10

07 Jun '10

moderator flag Question: Is there any reason why mod_conference should be modified to provide the “moderator” flag as part of the status on a list? I notice that it is provided by xml_list. Talking about xml_list. It does not seem to be documented and no caller within the Freeswitch C code. Is there any user? Regards, David Swardstrom (profile)http://wiki.freeswitch.org/wiki/User:Dswardstrom

Hi, any advice for a simple fees module ? NibbleBill seems to be interesting, but maybe there are others. I m only focused on call unit fees, no CDR or call details. Thanks Franck

speech recognition?
by Myron Curtis 07 Jun '10

07 Jun '10

Hi, I am developing a virtual world called Virtual Worlds Grid, and I am using FreeSwitch to provide voice. I would like to integrate it with a speech recognition engine like Simon, in order to have everything said in voice to be typed into text. This is one way to make the grid accessible for people who cannot use voice, and it also allows language translation software like Open Bablefish, to translate voice conversations from the resulting text files, which would facilitate multilingual conversations. I am new to the FreeSwitch system, and need some guidance on how to set this up. I would appreciate any tips, cautions, or links to practical help I can get. If this will work in a virtual world, there is no reason it cannot be made to work on cell phones. Thanks, Myron Curtis
