Using instant ringback.
by Kevin Snow 19 Mar '12

19 Mar '12

Hi, I'm experimenting with instant_ringback. It works perfectly but I'd like configure it to have a delay before starting. Making it not quite so instant. Many (maybe most) of our calls receive early media. Used in conjunction with instant_ringback it makes for a discontinuous ringback experience. First the user hears the instant_ringback, then it switches over to the early media ringback. Totally the right behavior but if I could configure instant ringback to start after X seconds I could avoid this for the user, except for cases where early media is slow to arrive. This would make a better customer experience. Is this possible? I looked into the teletone script syntax, hoping to insert a delay there but it didn't seem like I configure it with X seconds of silence then the ringback (and no more X seconds of silence). Thanks Kevin Snow

> I set it to true but it's still eating major CPU (80%+). According to the profiler 98% of the CPU time spent on the php function "sleep". So really the processor does not overload, it just "hangs" on sleep.

by Ken Rice 19 Mar '12

19 Mar '12

The FreeSWITCH Development Team is happy to announce that 1.2 is officially on the horizon. Starting Wed March 14th 2012, the Development branch of FreeSWITCH will reach a Feature Freeze. What does this mean for you the user? It means we will have a stable known feature set heading into the Release Candidate Cycle. Only patches that Fix Bugs will be accepted. If you have a feature you would like to see included, get us a Jira with a full patch set so we can evaluate its inclusion with 1.2. What we need from the community: Testing, Testing, more Testing, and Documentation Updates. The freeze will last 2 to 4 weeks as we spool up testing and everything else we need to get the Release Candidates ready for prime time. If you have outstanding bugs on Jira, please help us help you during this time by making sure all information on them is up to date. Grab the latest GIT Head and see if your bugs have been resolved and someone forgot to close your Jira. If you want to help or need some help diagnosing and issue visit us on IRC via irc.freenode.net/#freeswitch any time. The FreeSWITCH Dev Team

Early media buffered in bridge with ignore_early_media
by David Brazier 19 Mar '12

19 Mar '12

Hi All When we bridge one external call A to another B with ignore_early_media, then A hears nothing before B answers (as expected) but then hears ringing tones *after* B answers, and they can't otherwise hear each other until after that ringing has finished. The duration of this ringing appears to be related to the time B takes to answer, suggesting that what is happening is the early media from B is being buffered and not played back until after B answers. Easy to reproduce with: originate sofia/gateway/XXX/YYY &bridge({ignore_early_media=true}sofia/gateway/XXX/ZZZ) Doesn't happen with no ignore_early_media: originate sofia/gateway/XXX/YYY &bridge(sofia/gateway/XXX/ZZZ) Tested & problem is present on git-4276680 2012-03-14 10-08-41 -0500 but not an old build git-1086cba 2011-05-23 22-51-43 -0500 Have raised as http://jira.freeswitch.org/browse/FS-4009 but windering if anyone else has experienced this, or can reproduce it? Regards David

SLA unbuilding a conference
by Bob McCarthy 19 Mar '12

19 Mar '12

I have a customer who is using SLA who wishes to Blind Transfer a call after a conference has been built and has reduced to two parties. I have used uuid_bridge to "unconference". This action breaks any further SLA on the call, even though the lines are lit. Any other phone that tries to Barge in gets put into a single channel conference. The phone that had quit the conference fails on subsequent Barge attempts to the original call but can connect into a conference with the other phones if they have built the single channel. What I am asking is there a better way to accomplish this without breaking SLA ? I am basically trying to put the call back into the state it was in before the first SLA conference was built.

Advice how to start with H.323
by Peter Steinbach 19 Mar '12

19 Mar '12

I want to create a H323 Gateway in order to receive calls from an external H323 Server and transfer them to another Freeswitch server. I started on my Ubuntu 10.04 with mod_opal and spent some hours with trying the following 2 ways: * Using buildopal.sh, I had to adapt the script slightly and had to do some symlinks in order to progress. At the end I got stuck with a compile error "class PSTUNClient' has no member named 'InvalidateCache'" during compilation of opal manager * I then installed the libpt and libopal packes from apt and started to compile mod_opal. I then got stuck with a compile error "errror: no matching function for call to 'OpalLocalConnection::OpalLocalConnection(OpalCall&, FSEndPoint&, void*&, unsigned int&, OpalConnection::StringOptions*&)'" So this did not seem to be the right way as regards to future ability to compile it with system updates. Therefore I would like to ask you for some advice: * what is the best way to go: mod_opal or mod_h323? I think the feature set will be somehow the same for my purposes (I only need voice, PCMA), so I am asking, which one is more stable and compiles better. * what is best preferred platform (CentOS/Debian/??) for compiling this? * are there any dependencies for the opal and libpt versions? * Who had recently made running this solution and can give me some advice? -- With kind regards Peter Steinbach Telefaks Services GmbH mailto:lists (att) telefaks.de Internet:www.telefaks.de

If you get that warning in Windows, just start FS with "-monotonic-clock", then it won't be dependant of system time (as done by default on Linux systems). /Peter Från: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Brian Foster Skickat: den 19 mars 2012 03:39 Till: FreeSWITCH Users Help Ämne: Re: [Freeswitch-users] reverse time skew warning Well it is Windows...

reverse time skew warning
by Bote Man 19 Mar '12

19 Mar '12

What kind of problems can arise from the FreeSWITCH error message "Reverse time skew!"? I notice in the system logs that at the time of the FreeSWITCH complaint, ntp adjusted the system time backwards from 1:00:13.982493600Z to 1:00:13.982000000Z which is less than half a millisecond. That sounds negligible to you and mean, but that is an eternity for an android. I just hope it doesn't cause a serious problem down the road like a segfault or something every time ntp adjusts the time. Any comments? Thanks. Bote
