How to configure ring back for calls through freetdm?
by Antonio Modesto 14 Jun '12

14 Jun '12

Hi, I've written a lua script to make calls using freetdm channels, the problem is that there is not a ringback tone to the calling party, so it's not possible to know what is going on until the caller party answers the call. What do I have to do to enable this? Thanks.

ESL originate - call events are sent too fast
by Adam Raszynski 14 Jun '12

14 Jun '12

Hi all I have some little problem with events generated by ESL originated calls. Maybe someone had similar problem and could post how to solve it. I would like to originate call and receive events related only to that call. At the same time my originate script is executed multiple times i.e. 100 times. Current version of my script works like this: - send api originate [params]target via ESL - wait for originate response to get uuid - add filter: filter Unique-ID <uuid of my call> - subscribe for events: event plain CHANNEL_ANSWER CHANNEL_HANGUP CUSTOM spandsp::txfaxresult Unfortunately execution of all above statements sometimes take a while and in meanwhile FreeSWITCH generates event and send it back to my script BEFORE it has subscribed to receive events. It happens for example for very fast call answer or hangup. In that case I lost important answer or hangup event and all processing logic is broken. I've tried to change sequence of commands, but when I put event subscription before adding filter then I get events from other channels. I also can't add filter earlier because need to wait for originate response. Any hints on this?

playAndGetDigits working as designed?
by Alex Lake 14 Jun '12

14 Jun '12

I have the following in a lua script: session:streamFile(whisper) dtmf = session:playAndGetDigits(1,1,1,5000,"#",accept,accept,"\\d+") The idea is that the caller hears "Call for Alex of Wibble Corp"..."Press 1 to accept" and then he has 5s to press 1, otherwise it's assumed that the call has gone to mobile voicemail. What seems to be happening is: the caller hears "Call for Alex of Wibble Corp"..."Press 1 to accept" <pause 5s> "Press 1 to accept" <immediate hangup> (I'm surprised that it says it twice, and ignores the <timeout> attribute) Actually, I wouldn't mind something that went "Call for Alex of Wibble Corp"..."Press 1 to accept" <pause 3s> "Press 1 to accept" <pause 3s> <hangup> But telling the user to press 1 and IMMEDIATELY hanging up seems wrong!

NAT-ed phone only got some incoming calls?
by Avi Marcus 14 Jun '12

14 Jun '12

I have a customer with a natted Yealink T20P... Current reg: http://pastebin.freeswitch.org/19290 Two call traces, FS log side: http://pastebin.freeswitch.org/19286 One rang, one didn't. The local information for the phones is the same -- so NAT seems to be handled properly. Is this an issue with the remote router dropping packets or something...? I see 4 inbound calls to that device today, and 1 of them doesn't have a progress stamp so I assume that's the same as above -- it never got a 180 back. I think I can dig up the actual sip traces, if that matters, but it's not in the most convenient of formats. Some illumination would be appreciated. Thanks, -Avi Marcus

Does mod_fifo not take in effective_caller_id_name?
by esander83＠hushmail.com 14 Jun '12

14 Jun '12

Hi All, I have this basic dialplan: I can see the call get logged via the first extension but it's not passing the info to modfifo. I can remove the 2nd extension and put a basic: and the caller id name info is displayed on the phones but not when routing through mod_fifo. I have tried both set/export and it still doesn't seem to work. Is this correct? Thanks,eric_s

Jay, Yes I've seen about those ideas, and I think it's a really good way to handle this.

I'm thinking of writiling something similar for Windows, hopefully I get som time for that soon... /Peter if you do get round to writing something like this let me know. ( not that I even have a windows box ) but when I wrote the patches for FS to do the Fail2Ban compatible logging, I created ESL Events also with the intention that we could do a FS module "mod_security" or something ( no time given to the name ) it would be fairly simple to move some of the fail2ban functionality into such a module that could either call out to simple scripts or insert firewall rules its self. I have some ideas here, and I would probably be interested in working on this with others. Jay !DSPAM:4fd9b38232761034425819!

Missing event for "180 Ringing"?
by Dennis 14 Jun '12

14 Jun '12

Hi, for us it seems as if there is an event missing for 180 Ringing. Is there a way to receive/activate this event? We are using ESL and are getting nearly all events we need. For "183 Session Progress SDP" we get "channel_progress_media" and for "200 OK SDP" we get "channel_answer". So we only need one more event... Thanks for your help Dennis

Hello ! I have been looking at the documentation but am unable to find it. I wanted to know the correct syntax I need to issue via mod_event_socket if I want to collect DTMF and report back the digits entered to my application. Great if anybody can provide me with pointers. Venkatesh
