[Freeswitch-dev] Problem with sending DTMF on FXS port bridged to an FXO port
by devel＠thom.fr.eu.org 21 Apr '10

21 Apr '10

Hello, Im having trouble with this configuration with sangoma A400 card. What happens is this : the call is established (bridged from FXS to FXO) to an IVR, then the caller press some key. At that moment, the sangoma card detects the DTMF on the FXS channel, and queue the DTMF to be sent of the FXO channel. As a result, to the remote IVR, the DTMF is received twice (once inband, and a second time when generated from the FXO). I sometimes get an even worse scenario where the DTMF is detected by the card on both channels, and an endless loop start as the DTMF gets detected by the other channel when generated and so on and so forth. I tried to stop DTMF generation by adding the following lines to the dialplan before the bridge <action application="stop_dtmf" data=""/> <action application="stop_dtmf_generate" data=""/> <action application="bridge" data="openzap/2/2/$1"/> But this did not help. I could kindof solve the endless loop by modifying zap_io.c in zap_channel_set_state, when the new state is dialing (which means the FXO channel is an outbound one, and I therefore dont need DTMF detection) I do a zap_clear_flag(zchan, ZAP_CHANNEL_DTMF_DETECT); which prevent further DTMF detection on that channel. I dont know where to carry on now, as just preventing DTMF generation on outbound FXO channel would prevent DTMF generation where A leg is sofia or any other. François

Thanks for that I just wanted to quickly run the demos while I was logged in to window. Anyway I have now compiled a fresh install on Linux and have manged get up and running. The reason why I initialy asked about lua to control outbound sockets is because it is claimed that it is very fast however I am new too llua and for now I am sticking to php but how much is there a difference is speed and Is there a more optimal way to use php for sockets connections? II have setup socket connection to ivrd calling php with sucesscull execution of the script. There is one issue I have come across i am getting a error in doing the following command echo "sendmsg\n"; echo "call-command: execute\n"; echo "execute-app-name: playback\n\n"; echo "execute-app-arg: tone_stream://%(400,200,400,450);%(400,2200,400,450);loops=2\n\n"; IIt throws up the warning: switch_core_file.c:176 Sample rate doesn't match. Any ideas? On Thu, Apr 15, 2010 at 12:16 PM, vectorno vectorno <vectorno at googlemail.com > wrote: > IIs ivrd availible for windows > It doesn't look like ivrd builds in windows. I'll ask Jeff Lenk to check it out. -MC

[Freeswitch-dev] Using system libraries
by Daniel Dickinson 15 Apr '10

Hi, I'm working on an embedded OpenWRT system, and am now the package maintainer for FreeSWITCH on OpenWRT. I have FS successfully building and packaged (and installing and working) on brcm63xx, and building on the other OpenWRT architectures as well. With 1.0.6 the build doesn't require any patches, although it does require some finagling (as is to be expected) However, during the process of getting this to work for 1.0.6 I noticed that FS doesn't use system libraries, but instead uses it's own copies of packages it downloads, configures, and compiles and statically links. For OpenWRT this is problematic on two fronts. The first is that some packages require special build options to cross-compile properly, and the second is on embedded systems have statically copies of packages that are also on the system, uses up valuable storage and RAM. Would it be possible for the build system to support the *option* of using system versions of the packages instead of static-linked versions?

Ok, just to let you know it looks like I have the go ahead to create configuration switches (i.e. options) to do this, and I'll will be working on it (it won't be quick though, because I'm trying to get some more pressing work done first).
