Replace User-Agent and Server headers
by Kevin Olbrich 12 Dec '18

12 Dec '18

Hi! How can I replace User-Agent and Server headers in freeswitch? This is some kind of hardening (why tell people which version I use if the don't need to know...). Sure, I use the latest releases but I would like to hide the version I use or that I use freeswitch at all. Kind regards Kevin

Source device doesn't hangup videocall when the target device hangs
by Jose David Jurado Alonso 10 Dec '18

10 Dec '18

Hi! I call from a intercom (video door) to a mobile but when the mobile hangup the call, the intercom continues with the open call (it does not hang) and you have to press the button to hangup. That is, the video door phone does not hang when the call is hung from the mobile. I am using the external profile, intercom and mobile devices are in the same network but the server is in the cloud. The dialplan extension: ---------------------------------------------------------------------- <extension name="Local_Extension"> <condition field="destination_number" expression="^(.*)$"> <action application="export" data="dialed_extension=$1"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="continue_on_fail=true"/> <action application="set" data="ignore_early_media=true"/> <action application="set" data="execute_on_answer=sched_hangup +120" /> <action application="bridge" data="user/${dialed_extension}@ ${domain_name}"/> </condition> </extension> ---------------------------------------------------------------------- Thanks! Regards, José David Jurado Alonso

Forward/Transfer Leg A to another extension after bridge success
by Chhorm Chhatra 10 Dec '18

10 Dec '18

Hi, I'd like to know if there is any possible way to build a dialplan to forward/transfer Leg A to another extension based on B input from the keyboard. For example, Leg A call to Leg B (extension 1080), then Leg B answers and eventually, based on the conversation, Leg B may transfer Leg A to another extension (says, another department with extension 1090 for example). Best regards, Chhatra Chhorm

Hi, After deeply research about this issue, we understand *Freeswitch-Core* mechanism and three possible solutions for fixing these issue. Here the link https://stackoverflow.com/questions/53609817/freeswitch-blocked Actually it would be be better third solution supported by *Freeswitch*, before deliver event to module, it create new thread for not waiting consumer thread (event hendler) On Fri, Dec 22, 2017 at 8:35 AM Melek Oktay <melekoktay(a)gmail.com> wrote: > > Hi, > > FreeSwitch software working well in a few days (~3 - 5 days), then new > incoming call requests are accepted since FreeSwitch is blocked !!

Transfer Call to another extension from mod_callcenter
by Chhorm Chhatra 07 Dec '18

07 Dec '18

Hi, Is it possible for mod_callcenter agent to transfer the call to another extension based on DTMF keyboard input from the agent? For example, a user calls to the agent, the agent then answers it. After some conversation, the agent transfers the user to another department by entering the keyboard input from the phone. Any help would be appreciated. For example Best regards, Chhatra Chhorm

Mutli-lingual ivr
by Darcy Primrose 06 Dec '18

06 Dec '18

We are long time freeswitch users in an area of Canada where there is a strong english french mix. We have for some time be providing a multi-lingual experience for the extensions/users quite successfully but have not been able to get the ivr to switch to a second language. Has anyone had experience or success with this. We use en as our prime language code but when specific DIDs are dialed, we would like the IVR responses to be in french. First, is this possible in freeswitch and if so, does anyone have any hints on how to accomplish this. Thanks Darcy Primrose Voice2Net

P-Asserted-Identity transparency between leg A and leg B
by igor.potjevlesch＠gmail.com 06 Dec '18

06 Dec '18

Hello, In the scenario where the From is different than the P-Asserted-Identity on leg A, FS put the PAI in the From on leg B. I don't find how to change this behaviour. I would like to keep the From and the P-Asserted-Identity as they come on the leg A except some manipulations. Someone knows which parameters must be changed? Currently, the leg B is configured with "pass-callee-id" to false, "caller-id-in-from" to true and "caller-id-type" to "pid". Regards, Igor.

Setup Verto in Local to Replace SIP
by Chhorm Chhatra 06 Dec '18

06 Dec '18

Hi, I am not sure if this approach is still being used these days, but I'd like to know if there is any guide out there to set up Verto in Local (No SSL certificates required). My use case is that we don't want to involve with the Internet yet we still want the call to be established via Verto rather than SIP since SIP is not supported by the latest version of Android out of the box. Any help would be appreciated. Best regards, Chhatra Chhorm
