can I overwrite channel var with response headers ?
by jay binks 14 May '11

14 May '11

I have 2 FS boxes ... BoxA & BoxB BoxA invites to BoxB and I want BoxB to respond with some information to place in the channel vars on BoxA ( to store in the CDR there ) ive found I can use sip_ph_X-blah & sip_rh_X-blah to pass the data back ( in different messages obviously ) however neither of these overwrite the "blah" channel variable.. is there a way to tell FS to overwrite channel var "blah" with these sip responses ? -- Sincerely Jay

Can UUID's change?
by Mark Sobkow 13 May '11

13 May '11

Here's our scenario: The operator logs in to our system, and has their UUID parked. The system calls the customer when requested, which creates a UUID. The operator and customer UUIDs are bridged. We watch for events from the customer UUID to determine when the customer has hung up their end of the call, which causes the operator to be parked again. However, I'm seeing some unrecognized UUIDs after bridging the call (i.e. that weren't returned by the place call code.) Are there any events which might indicate that a UUID is being changed by the system, and that I should be watching for a new UUID instead? -- Mark Sobkow Senior Developer MarkeTel Multi-Line Dialing Systems LTD. 428 Victoria Ave Regina, SK S4N-0P6 Toll-Free: 800-289-8616-X533 Local: 306-359-6893-X533 Fax: 306-359-6879 Email: m.sobkow(a)marketelsystems.com Web: http://www.marketelsystems.com Visit our Blog for industry related information. http://marketel-systems.blogspot.com/

Fifo - exporting/Importing variables from A to B Leg
by Marc de Corny 13 May '11

13 May '11

Hi all, I'm back on working on my test freeswitch lab box. got two questions which on which somebody can maybe shed some light. 1. Is it possible to export variables from the A-leg of the queue to the B-let of the queue? There are the export and import commands, but not sure if they are applicable. If I capture calls coming out of the queue with a loopback I could then act using the variables that have been set from the A-leg. 2. I'd like to send the call to the Freeswitch to play IVRs etc and then bridge it without the audio. I know it can be done on a normal bridge with bypass_media_after_bridge, but not so sure on a fifo call. Many thanks for any help Marc

MEDIA_BUG_START
by Mark Sobkow 13 May '11

13 May '11

I'm getting a MEDIA_BUG_START event. I think there's a correlation between this event and some dropped calls we're experiencing. I haven't found any way to force the event to occur, so I haven't been able to capture a log file of it happening in fs_cli. Our FreeSwitch box is configured to use a SIP Trunk provided by our production Asterisk box, with T1 lines from thereon out. For the most part it works, but one user in particular has a serious problem with dropped calls and I'm trying to figure it out. -- Mark Sobkow Senior Developer MarkeTel Multi-Line Dialing Systems LTD. 428 Victoria Ave Regina, SK S4N-0P6 Toll-Free: 800-289-8616-X533 Local: 306-359-6893-X533 Fax: 306-359-6879 Email: m.sobkow(a)marketelsystems.com Web: http://www.marketelsystems.com Visit our Blog for industry related information. http://marketel-systems.blogspot.com/

Hi there, I am new to FreeSwitch, and I have a question to ask. If I want to read the RTP package in C++ or C#, what function should I call to get it? Currently I have can make a call to a phone and play an audio. Thanks in advance. Frankie ____________________________________________________________________________________ Expecting?

Need help on a calling card service
by Alfred Stainer 13 May '11

13 May '11

Hi all, we are developing a calling card service based on Freeswitch and we have the necessity to implement the following features but we have not found a way to do that: we want that the first 10 seconds of the call are free of charge for the caller. This is not only a billing issue because most of our customers don't call a free number so we want that the connect to the caller is sent only after 10 seconds we receive the connect from called. We bridge the inbound leg with the outbound leg but we are not capable to delay the propagation of the connect. The perfect solution will be that when we receive the connect from outgoing leg we send the preanswer on incoming leg and 10 second after that we send the connect. There is a way to do that? Any advice? Alfred

does anyone know what the SIP equivalent is to "2 b channel transfer". taking an inbound and an outbound, drop operator out, and pass the call up to the telco? Thanks, Dave

Playing remote prompts
by Adam Kelloway 12 May '11

12 May '11

If I did not wish to store audio files on a FreeSWITCH host, what are my options for being able to retrieve a remote file and playing it? My understanding is that the playback application can only play a local file, is that correct? I did notice that there is a shell_stream module, which you could potentially use to retrieve a file (say, via HTTP), and provide the audio data as the output bash script output. Is there a way to do this or something similar without having to actually load another program/script? Thanks, Adam Kelloway
