nonetheless, can you please see my bugnote in jira. ===== can you edit /usr/local/freeswitch/conf/autoload_configs/iax.conf.xml and set the debug param to 1. Then reproduce the case where it's not working. We can see if the mod_iax is even getting the digits. ===== also be sure to sync to the current release by entering "make current" from the build root.

IAX2 messages are properly acked, sound (between IAX2 and SIP) is ok, etc, etc. The problem is (only) with DTMF, as far as I can tell. It's more likely to be in core or sofia_sip?

How to do load balancing in freeswitch
by Krunal Patel 09 Sep '08

09 Sep '08

Hi, Here is the scenario: **Whatever call comes to freeswitch will be forwarded to terminators. **Now I would like to do load balance to send call to terminators as per there weight. For example there are two terminator having weight 75 & 25. So 75 % calls should be forwarded to first terminator & 25% should be forwarded to another. So please help me to resolve this. Thanks, Krunal Patel

FXS problem
by Luis Manuel Zuccolo 08 Sep '08

08 Sep '08

Hi, I'm usign an openvox card with 2 fxo modules and 1 fxs module. When I dial from fxs extension only take the first digit dialed and tried to route the call. This digit is not in dialplan, then the call is hung up. This happend only in FreeSWITCH snapshot (2008-08-31 and 2008-09-6). In release 1.0.1 work well. It's look like that don't take the option digit-timeout configured to 2000 in openzap.conf.xml Am I' missing something else? Any help about this would be appreciated. Thanks in advance.

Re: [Freeswitch-users] SIP, NAT and Amazon EC2
by Novak Joe 08 Sep '08

08 Sep '08

Hi, When I first tried setting up freeswitch on ec2 I attempted to do this through the quick and dirty wiki: http://wiki.freeswitch.org/wiki/Quick_and_Dirty_Install and the ec2 wiki http://wiki.freeswitch.org/wiki/Amazon_ec2 This didn't work out for me. You also need to take a careful look at http://wiki.freeswitch.org/wiki/Getting_Started_Guide#Firewall then, for sip, setup a security group with the following ports enabled (easiest to do with elasticfox http://developer.amazonwebservices.com/connect/entry.jspa?externalID=609 ): udp 16384:32768 udp 4569 udp 5060 tcp 5060 udp 5080 tcp 5080 tcp 8000 udp 8000 make sure you make the security group, and apply it before you boot the instance. after this, the quick and dirty install guid worked just fine for me. you'll just need to tweak the default dialplan to your needs. cheers Hi Brian, Did you have any luck with the EC2 instances. I tried a few things, but I just cant get RTP to run through it. PLease let me know.

Setting hangup hook from Perl?
by Nic Wolff 08 Sep '08

08 Sep '08

How do I set a hangup hook function in a Perl application called from the dialplan? After looking at freeswitch.pm I tried these: freeswitch::setHangupHook( &on_hangup ); $session->setHangupHook( &on_hangup ); but both failed with errors. Thanks - Nic

post-hangup processing
by Novak Joe 08 Sep '08

08 Sep '08

Hi, I am new to freeswitch, and have successfully set it up with mod_python, and put together some IVR dialogues. It seems amazingly easy to use, however I have a question about running post-processing after a hangup. I would like to run some time-consuming post processing on the recordings I make, after I hang up and I'm not sure how best to approach this. I would prefer not to use the async module as I am not so familiar with twisted, and I note that at the moment I can hangup up the call and have no problem processing the data I've recorded, however I also note that if I don't hang up the call, my sip client stays on the line until the processing finishes. I tried to send session.hangup("1") before I run the post processing commands, but this doesn't seem to have any effect. It seems there must be a way to get around using twisted, but maybe not? Cheers

SIP, NAT and Amazon EC2
by Damon Brown 08 Sep '08

08 Sep '08

Hello All, I have installed freeswitch on a computing cloud (Amazon EC2). My main network configurations are: (FreeSwitch ARI LAN ) <---> (WAN) <------{INTERNET} -------> (WAN) <----> (SIP Soft or Hard Phone LAN) I have pointed all of my clients to the external (5080) sip port .... No matter what I try STUN, Port Forwarding or the "Use Asterisk Method" settings in the directory, I get no audio. My guess would be the RTP side, but at this point I feel like I have done everything I can and still be a FreeSwitch Newb. Can anyone provide any in-site? Seems like a great system ... more directly the idea of no hardware dependency! Thanks in advance Damon

running FS in the Amazon cloud / other scalability options
by Brian B 08 Sep '08

08 Sep '08

Our FS app will be under near-zero load much of the time, and then spike with our large (highly customized) conference call applications. So, we'd like to investigate running it in an easily scalable environment, a la the Amazon cloud. Three questions 1) Are the current images available here *current*, can someone tell from the version numbers? I looked for version history on the wiki but couldn't find it. The amazon command line command: ec2-describe-images -x all -v |grep freeswitch yields the following three (repeated in the verbose mode) <imageLocation>rbuilder-online/freeswitch-0.0.1-x86_11952.img.manifest.xml</imageLocation> <imageLocation>freeswitch-fedora-6-svn-rev-9178/image.manifest.xml</imageLocation> <imageLocation>rbuilder-online/freeswitch-0.0.1-x86_11963.img.manifest.xml</imageLocation> IMAGE ami-999672f0 freeswitch-fedora-6-svn-rev-9178/image.manifest.xml 811137716590 available public x86_64 machine IMAGE ami-1be30672 rbuilder-online/freeswitch-0.0.1-x86_11952.img.manifest.xml 099034111737 available public i386 machine IMAGE ami-dae306b3 rbuilder-online/freeswitch-0.0.1-x86_11963.img.manifest.xml 099034111737 available public i386 machine 2) If not, does anyone want to help set up a current Amazon image? I'll provide the Amazon account if you can install FS in it. 3) Does anyone have other recommendations for services that can burst to high usage, without paying for high usage 24x7? I don't see VPS providers that can burst to much RAM/CPU for the few hours/month we'll need it. Thanks! -- =========================== Brian Burt 415-308-4258 mobile (best) freeswitch(a)brian-burt.com ===========================
