Freeswitch dialing Via Broadband phone
by Prashant Choudhary 30 Aug '15

30 Aug '15

Hello, I have my FreeSwitch configured in my local machine. I am using a broadband connection which comes with additional phone line connected via ADSL splitter. Which can be used to make calls, The router has the details of the phone connection. Now the thing is, can I use Freeswitch configured under same router to make outbound calls. Thanks

FreeSwitch modems flow control?
by Alex Crow 29 Aug '15

29 Aug '15

Hi, I asked this question a *long* time ago as I was having major problems receiving faxes using HylaFAX and the builtin FS Modems, in that the FS Modems did not have any kind of flow control, which resulted in a repeated backing off of baud rate until the incoming faxes failed with a rate of over 50%. Has there been any change in the softmodem code to add flow control so that this does not happen any more? Best regards Alex

Unable to get channel variables from directory to dialplan.
by Vladislav Ivanov 29 Aug '15

29 Aug '15

Good Day, I have been trying to set up the sip phone at my home, and i'm having some issues with channel variables. >From what I have read: https://wiki.freeswitch.org/wiki/Routing_with_directory_parameters I should force per-call authentication in your sofia.xml.conf for <variables> to be passed through to the dialplan. But I were unable to find this option in sofia/sofia_default files. https://freeswitch.org/confluence/display/FREESWITCH/Channel+Variables - Although here there is nothing about "per-call authentication". And I'm not sure how to proceed. I have this directory xml: <include> <user id="123123"> <params> <param name="password" value="123123"/> </params> <variables> <variable name="accountcode" value="123123"/> <variable name="user_context" value="test_context"/> <variable name="effective_caller_id_name" value="Test Phone"/> <variable name="effective_caller_id_number" value="123123"/> <variable name="outbound_caller_id_name" value="$${outbound_caller_name}"/> <variable name="outbound_caller_id_number" value="$${outbound_caller_id}"/> </variables> </user> </include> Directory variables should be passed as ${variable} as they are channel variables? I have Dialplan as follows: <extension name="registrar_test"> <condition field="destination_number" expression="^(.*)$"> <action application="log" data="ERR TestMessage [${user_context}]"/> <action application="respond" data="503 Route Successfull"/> </condition> </extension> <extension name="all_reject"> <condition field="destination_number" expression="^(.*)$"> <action application="respond" data="503 No Route"/> </condition> </extension> When I dial the call I get TestMessage [] instead of test_context. Also, wrapping registrar_test extension with <context name="test_context"></context> doesn't help, my call will go to "all_reject" extension. What do I miss? Best Regards, Vlad

HI all, Was wondering if anyone is using FreeSWITCH to receive faxes over a SIP trunk, and what the experience has been like. I know I've heard this can be difficult, but was interested in real experiences. Thanks, Mike

OPUS, pjsip, csipsimple bug for 1 chanel
by Tim Meade 29 Aug '15

29 Aug '15

We are playing around with opus on iOS and freeswitch. Dialing out from iOS through FS shows this: Invalid SDP for opus. Don't ask.. but it needs a /2 FS seems to fix the invalid opus and the call sounds fantastic. The problem is on sending opus TO the iOS device. FS is sending: a=rtpmap:102 opus/48000/2. Which is correct and true. We are reading that this particular implementation of opus from cSipSimple has a know bug on the /2 it just wants opus/48000. Does anyone know of a fix for either the cSipSimple side or a workaround for FS to just send the opus/48000. ? Thanks Tim

Unable to continue dialplan if legB fails on early-media with multiple destination
by gdesai 29 Aug '15

29 Aug '15

I need to implement following scenario: 1) Leg A comes to FS. 2) FS answers the call and plays a prompt. 3) FS originates leg B (with two destination) 4) Leg B sends ringback tone for source. 5) If Leg A does not answer, FS tries second destination. Problem is when Leg B does not answer, FS hangs up Leg B. When Leg B hangs up, FS also hangs up Leg A. Instead of keeping Leg A and dialing second destination. My originate dialplan: originate {origination_caller_id_number=18888888888,ignore_early_media=true,park_after_bridge=true}[origination_uuid=uuid,sip_h_Subject='"Direct" 17777777777'][leg_timeout=15,park_after_bridge=true]sofia/gateway/40/5555555555,[leg_delay_start=12]sofia/gateway/40/4444444444'&managed(CallCloudAppServer.Service.OutboundLeg)' Note: When early media is received from Leg B, I am bridging both legs and then park Leg A. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Unable-to-continue-dialplan-i… Sent from the freeswitch-users mailing list archive at Nabble.com.

JSON-based API calls
by David McNab 29 Aug '15

29 Aug '15

Hi there, How do you do API calls in JSON? Or, how do I get a list of all the API calls which can receive JSON parameters and return JSON return values? For example, in the console, I tried 'show calls', and got a list of calls. I did the same call from via XML-RPC from a python script, and got a single string back, containing what would have been output to the console. But when I tried, from the console: *json {"command":"show calls", "format":"pretty", "data":{}}* I got an invalid response. I also tried: *json {"command":"show", "format":"pretty", "data":"calls"}* but got similar. Is there a general sceme for invoking all the console API commands (and receiving responses) in JSON format? If not, I guess I need to write some parsers to process each command's output string. Cheers David

Pickup from a Queue - mod_callcenter
by Raphael Lechner 28 Aug '15

28 Aug '15

Hi, We have a customer that want to Pickup from time to time a call from a queue. It seems that picking up a call from a Queue is not intended to be used in combination with a Queue or I’m wrong with that? I created a solution for that customer that store the UUID in a database via a python script before the caller gets into the queue and a function to retrieve that UUID if the caller is still in the queue and to pick up with that UUID. After the call get answered the UUID get deleted. This function is working fine, but maybe somebody knows a better way to picking up calls from a Queue? Thanks in advance, Raphael
