Errors compiling on dragonfly bsd
by Vincent 31 Mar '09

31 Mar '09

Hi. I'm trying to compile FS on dragonfly BSD 1.10.1-RELEASE. I am compiling the release source from http://files.freeswitch.org/freeswitch-1.0.3.tar.gz I had to write a uname wrapper script to fake being FreeBSD to get configure to complete successfully. I also added "-D__FreeBSD__" to CPPFLAGS to get past an initial compilation error. Also, I initially got the error, "/usr/pkg/bin/bash: line 8: svnversion: command not found" just prior to the line that appears to generate "src/include/switch_swigable_cpp.h". It seems strange that I would need subversion to compile a release source but I installed it anyway in case that error caused other problems. However, now I get the following errors (which I also got prior to installing subversion). Compiling src/switch_apr.c ... src/switch_apr.c: In function `switch_thread_self': src/switch_apr.c:74: warning: implicit declaration of function `apr_os_thread_current' src/switch_apr.c:74: warning: return makes pointer from integer without a cast src/switch_apr.c: In function `switch_thread_rwlock_create': src/switch_apr.c:221: warning: implicit declaration of function `apr_thread_rwlock_create' src/switch_apr.c: In function `switch_thread_rwlock_destroy': src/switch_apr.c:226: warning: implicit declaration of function `apr_thread_rwlock_destroy' ...

It does not seem to check the error code either and still gives a "Build Complete" message. Any help would be appreciated.

Help scripting tone_detect.
by mszlazak＠aol.com 30 Mar '09

30 Mar '09

Except for fields in a dial plan extension, I can't get tone_detect (or stop_tone_detect), http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_stop_tone_detect to work in JavaScript. If there is one, what's the correct syntax for scripting these? Mark.

differences between mod_fifo and asterisk queues
by Francois Delawarde 30 Mar '09

30 Mar '09

Hello and welcome me into FreeSWITCH's world! <= sorry that was rude I am (hoping to say "I was" soon) a heavy user of Asterisk's call queues for small call centers with sometimes empty queues and all agents idle for a few seconds. FreeSWITCH's mod_fifo algorithm is apparently quite different than Asterisk's app_queue. Instead of choosing an agent for a each call once it gets to the bottom of the queue given a specific strategy, FreeSWITCH does the inverse and finds a call once an agent is free given a strategy (the call that has waited longer from all the agent's queues, or the call in the queue that currently has more calls waiting). Am I right? If the above deduction is correct, while it seems a MUCH better choice for heavier call centers that always have calls in their queues ("in queue" calls are not delayed by the processing of the call at the end of the queue), I have a few doubts for what would happen in small call centers when those queues sometimes get empty and several agents "fight" for the incoming calls. My questions are following: - If for example 4 agents are "connected" (fifo out) to an empty queue, what happens when a call arrives? Do the 4 agents ring? If not, how do we know which agent get the call? - Is there an [easy] way (with some javascript or similar) to "emulate" Asterisk's distribution strategies to agents (by amount of time without calls, total number of answered calls, round robing, ...) in this cases? A couple of other newbie questions that has nothing to do with the above: - Is there a way to execute some PHP scripts for each call that would do the bridging or call applications (like Asterisk's AGI)? - What is the recommended language for features, speed, and programming ease (not a priority) for this kind of scripts (C? LUA?, Javascript?, ..)? Thanks in advance, François.

freeswitch as a session border controller
by Robert McNaught 30 Mar '09

30 Mar '09

Hi, I have been reading the recent news articles about freeswitch. I am particularly interested in using it to replace a session border controller we have (kagoor voiceflow 1000). Has anyone actually used this in production as a session border controller for NAT traversal? Thanks Robert McNaught

H323 supported devices
by Christian Bourke 30 Mar '09

30 Mar '09

Hi, I would like to implement freeswitch as a H323 gateway. I would like to be able to receive calls from H323 devices such as Polycom V500 and Dlink DVC-1000. Does anyone know if this is possible?

Freeswitch Hunt Group
by Christian Bourke 30 Mar '09

30 Mar '09

Hi, I would like to implement freeswitch as an H323 gatekeeper. I would like to know if its possible for incoming H323 calls to go into a hunt group, if no 'operators' are logged into the hunt group then the call will bounce to an auto attendant and the H323 caller will be played a short video message then freeswitch will disconnect the call. Does this sound possible with Freeswitch? Thanks,

how to do upper registration
by xbipin 30 Mar '09

30 Mar '09

i have been trying to do this but seem to have been lost, actually i want to use freeswitch as a session border controller so basically all the clients that try to register to FS will actually be authenticated voipswitch but i want FS to be in between and proxy everything and with any of its advanced options turned off. -- View this message in context: http://www.nabble.com/how-to-do-upper-registration-tp22743580p22743580.html Sent from the Freeswitch-users mailing list archive at Nabble.com.

echo cancellation on PRI cards
by Anthony Knight 30 Mar '09

30 Mar '09

I'm thinking about doing a project that would use FreeSWITCH as an IVR, with callers being routed in by both ISDN PRI, and also SIP trunks, with occasional bridge calls between callers. I'm wondering in what use cases hardware echo cancellation on the PRI cards is needed. And does hardware echo cancellation work with OpenZap/FreeSWITCH? It looks like all the major cards (Sangoma, Digium, etc..) use Octasic Echo cancellation add-on cards. Is there any difference between brands? Any recommendations on PRI boards and whether I need to pay for echo cancellation are appreciated Thanks. Tony

mod_skypiax
by Dave Cabot 29 Mar '09

29 Mar '09

Hi folks. I've been playing with mod_skypiax. 1) it seems that the documentation web pages are out of date. http://jira.freeswitch.org/ rejects connections. I'm running FreeSWITCH Version 1.0.trunk (12826). I'm using Xvfb and skype 2.0.0.72-1_i386.deb. I can make a call and sound is great, but then when the call ends, so does skype.
