get BYE event in javascripts
by Khue Nguyen Minh 04 Oct '13

04 Oct '13

Hi all, I have a simple javascripts with simple scenario. In this scenario, user can listen audio and send dtmf to play next or previous audio file. When user send dtmf to play other audio file, I will store play time of this audio to a text file (time.txt), but, if user hangup this call, the play time of last file cannot store in time.txt. How I can capture event user hangup to store play time into time.txt before javascripts session destroyed? Brs, Khue.

Problem with NAT configuration. Trying to understand autonat.
by Federico Castro 04 Oct '13

04 Oct '13

Hi everybody, please someone could help me to understand what "autonat:" makes when is used to modify ext-rtp-ip and ext-sip-ip in profiles. I faced the problem I'm going to explain and I solved it using "autonat" but I couldn't understand why it fixed my problem: *Problem:* Calls from SIP phones are dropped after 32 seconds *Scenario (not real IPs):* FS IP: 172.23.9.4 IP phone "A": 172.23.9.5 IP phone "B": 172.23.9.10 FS is behind NAT to call some VoIP providers. Public IP: 190.190.190.190 *What happens:* IP phone "A" calls IP phone "B", no NAT is necesary. All devices are in the same LAN, FS and both IP phones. I copy below profile configuration and 200 OK message that freeswitch sends to IP phone "A" when call is answered. Contact header is wrong, it is using Public IP instead of local IP. It produces that ACK from IP phone "A" never reaches FS and call is dropped by timeout. In profile configuration file: <param name="ext-rtp-ip" value="190.190.190.190"/> <param name="ext-sip-ip" value="190.190.190.190"/> Then, I changed to: <param name="ext-rtp-ip" value="autonat:190.190.190.190"/> <param name="ext-sip-ip" value="autonat:190.190.190.190"/> And it solved my problem. *My Questions:* Why when I dont use autonat "contact header" contains public IP if all devices are in the local network? And why autonat change this behaviour? Thanks for your help.

Update SDP of Leg-B
by mehroz 03 Oct '13

03 Oct '13

Hi All, I am facing audio/video and video/audio switching issue under proxy media mode. It looks as of SDP does not update itself on the B-leg. OR if it does, it doesn't transmit video RTP after a switch from audio only. With the default media mode, this is achievable but , it b-Leg doesn't see any call update and hence pauses the video . 1) is there a way to explicitly change the SDP to be transmitted ? (proxy mode) 2) Any trigger or event at the B-leg to update the call , one A has done so (default mode) -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Update-SDP-of-Leg-B-tp7595445… Sent from the freeswitch-users mailing list archive at Nabble.com.

sofia's SLA confusing caller_profiles
by Vik Killa 03 Oct '13

03 Oct '13

im may be wrong about this but it is confusing.... when an outbound call (B-leg) is "stolen" via SLA (sofia's intercept, meaning that A-leg pushes hold and a new leg, C-leg, is created when another phone hit's the line key to bridge to the B-leg) the B-leg's caller_profile contains an originator_caller_profile of the new C-leg's caller_profile and the C-leg's caller_profile contains an originatee_caller_profile of B-leg's caller_profile this seems counter-intuitive and backwards compared to how it functions in all other scenarios shouldn't the original B-leg have an originatee_caller_profile and the new C-leg have an originator_caller_profile? since the C-leg is the NEW leg, it should have an originator, no? and since the B-leg already exists, it should have an originatee? Thanks

Conference Configure Multiple Prompts
by Callum Guy 03 Oct '13

03 Oct '13

Hi All, I am working with the conference application and controlling it remotely with ESL. I have a requirement to assign multiple prompts to the same event - in this case conference join. I have configured an application to record a users name, and wish to play "NAME..." followed by a default prompt "..has joined the conference". Similarly i plan to use the same idea when callers leave the conference. I am first looking at the application parameters in "autoload_configs/conference.conf.xml" and wondering if there is a way to share a list of prompts - something along the lines of the following which i naively hoped would repeat the prompt twice (obviously it doesn't work, otherwise i wouldn't be asking!): <param name="alone-sound" value="/usr/share/sounds/ConferencingOnlyPerson.wav /usr/share/sounds/ConferencingOnlyPerson.wav"/> I can advance this by changing strategy and broadcasting an event (play application) to all known conference members however i suspect there may be a better and cleaner way of doing this so i'm putting the question to the community! Any help/pointers would be greatly appreciated. Best Regards, Callum

FreeTDM rpm issue
by DN Singh 03 Oct '13

03 Oct '13

Hi list, I am installing freetdm library via yum repo in Centos 5. The problem is that even though it gets installed, I do not get ftmod_wanpipe.so which this file is supposed to provide. Can anybody help me on this issue? Would I have to compile and install freeswitch, just for this particular library? NOTE: I do have wanpipe and libsng_isdn already installed on it.

Hi, Can anyone tell me what the callgroup variable is used for in the user.xml (1000.xml) file please? Does it relate to a "ring" group, or "call pickup" group? Thanks in advance. Richard
