Getting digits from <playback>
by 'Yemi Obembe 30 Aug '17

30 Aug '17

I am using HTTAPI and need to get user input sent to a URL. The idea is this: play audio, get user input and send it to a URL. Every attempt hasn't worked so far. fs_cli shows the input from the user. It's just not getting to the URL. Here are what I have tried: This sends some details to the playback action URL but nothing about the user input is sent. <document type="text/freeswitch-httapi"> <work> <playback file="https://server/path/to/file" digit-timeout="5000" name="user_input" terminators="#" action="https://requestb.in/1gzfx1g1"> <bind>~\d{3}#}</bind> </playback> </work></document> Tried putting action in <bind>. Doesn't work too: <document type="text/freeswitch-httapi"> <work> <playback file="https://server/path/to/file" digit-timeout="5000" name="user_input" terminators="#"> <bind action="https://requestb.in/1gzfx1g1">~\d{3}#}</bind> </playback> </work></document> Using execute/play_and_get_digits doesn't either: <document type="text/freeswitch-httapi"><params></params><variables><digits>0</digits></variables><work> <execute action="https://requestb.in/1gzfx1g1" application="play_and_get_digits" data="2 5 3 8000 # https://server/path/to/file '' digits \d{3} " /></work> </document>

Is there maximum number of TLS registrations?
by Yehavi Bourvine 30 Aug '17

30 Aug '17

Hello, I would like to move all our phones to TLS. Is there some limitation in Freeswitch (or a Linux parameter to watch) which might limit these registrations? I am now doing it slowly, and have a problem with Yealink T19P which tries to create a new registration once every few minutes (leaving the other registration alive). T19P_E2 works ok so far. Thanks, __Yehavi:

CHANNEL_EXECUTE_COMPLETE - variable_current_application and Application
by Markus Bönke 30 Aug '17

30 Aug '17

Hello, I want to clarify the signaling of CHANNEL_EXECUTE_COMPLETE events via the ESL socket. Especially on transfers / blind transfers I’m a bit confused how CHANNEL_EXECUTE_COMPLETE are sent and how the variables are set. The call scenario is the following: * A call control is sent to a ESL application via socket application. * The call is bridged to a SIP user. * The SIP user initiates a blind transfer to another phone number When the bind transfer is initiated, I get a CHANNEL_EXECUTE_COMPLETE event where the channel variables are set as follows: variable_current_application_data: sounds/moh.wav variable_current_application: playback variable_current_application_response: PLAYBACK%20ERROR Application: bridge Application-Data: ... Application-Response: PLAYBACK%20ERROR Application-UUID: 1420bfcd-63cd-4445-afa8-6e6c17c07d69 The Application-UUID "1420bfcd-63cd-4445-afa8-6e6c17c07d69 "belongs to the „bridge" command of the call send through ESL. But the Application-Response is set to PLAYBACK%20ERROR“, however the application response belongs to a playback command which was implicitly triggered when the call is put on hold. It seems on a blind transfer the call is first put on hold for a second and then bridged again. As the MOH is interrupted, the Application-Response is set to PLAYBACK%20ERROR. I see the same variables also in the CHANNEL_EXECUTE_COMPLETE belonging to the „socket“ which I get in the end of the call. variable_current_application_data: sounds/tevox-standard-moh-2.wav variable_current_application: playback variable_current_application_response: PLAYBACK%20ERROR Application: socket Application-Data: 192.168.154.209%3A8029%20async%20full Application-Response: PLAYBACK%20ERROR Application-UUID: 3a923054-89a5-11e7-a87d-e97d1c60b3f1 To be able to implement the processing of CHANNEL_EXECUTE_COMPLETE properly for all call scenarios, I need to understand the signaling in depth. Here in conclusion what I can see in the ESL trace: * I can get several CHANNEL_EXECUTE_COMPLETE events for an application that is executed, not just only one. * An application can trigger/execute other applications (Like playback in scope of executing a bridge command and blind transfer). * I also receive a CHANNEL_EXECUTE_COMPLETE event for those „implicit" executed applications. * In addition, I get a CHANNEL_EXECUTE_COMPLETE with the Application-UUID of the initial application. The channel variable "Application-Response" contains the last response that was generated in scope of the application that was executed belonging to the Application-UUID. If an other application was executed in scope of this application, the variables current_application, current_application_data and current_application_response are set. In this case the variable Application-Response = variable_current_application_response. I’ve tested this with older and the latest freeswitch version, the behavior seems to be by design. Questions: Why do I get a CHANNEL_EXECUTE_COMPLETE in scope of the bridge application at all (Or is this a bug)? Why is the Application-Response set to PLAYBACK%20ERROR (the current / last executed application)? Why is there no variable_current_application_uuid? Any comments are welcome Markus

Destination number from Request-URI
by Saeed Musani 29 Aug '17

29 Aug '17

Hi, I want to know whether FreeSwitch extracts destination number from Request-URI or from "To" header. I suspect that it extracts from "To" header. If this is the case, please guide me how we can configure FreeSwitch to extract destination number from Request-URI. I have googled it but unable to find the solution. Thanks for the support. Best Wishes, Muhammad Saeed Musani

What is the best ESL Go library? By best I mean complete, maintained, bug free, efficient, etc. There seem to be MANY alternative Go ESL packages. I am wondering which ones are being actively and successfully used. Recommendations? Some of the ones I found: https://github.com/fiorix/go-eventsocket https://github.com/0x19/goesl https://github.com/mattwilliamson/go-eventsocket https://github.com/cgrates/fsock https://github.com/vma/esl Thanks, -- Guillermo Ruiz Camauer
