FreeTDM and Digium analog cards
by Joseph L. Casale 14 Aug '10

Does FreeTDM support TDM cards, or just the digital variants? Reading through Sangoma's docs on FreeTDM, it's not clear? Thanks!

Re: [Freeswitch-users] Strange early media SDP behavior

I missed the part about bypass_media but offer/answer stays the same. In this case the remote end is selecting PCMU from the advertised codec list. What is it configured to do? Do you have a full trace showing both legs? It's not clear from the few SDPs you've posted which endpoint is which, where fs is, etc. -- Kristian Kielhofner http://blog.krisk.org ----- Original Message ----- From: freeswitch-users-bounces(a)lists.freeswitch.org <freeswitch-users-bounces(a)lists.freeswitch.org> To: FreeSWITCH Users Help <freeswitch-users(a)lists.freeswitch.org> Sent: Sat Aug 14 11:36:20 2010 Subject: Re: [Freeswitch-users] Strange early media SDP behavior I would disagree, in bypass media mode FS is supposed to forward SDP as is, let endpoints to negotiate the codec.

It's standard SDP offer/answer. Fresswitch will not send three audio streams with three codecs. You're advertising three codecs with PCMU first. Freeswitch supports PCMU in your configuration and agrees on that codec. There are several configuration options in freeswitch and the phone that can influence this behavior. -- Kristian Kielhofner http://blog.krisk.org ----- Original Message ----- From: freeswitch-users-bounces(a)lists.freeswitch.org <freeswitch-users-bounces(a)lists.freeswitch.org> To: FreeSWITCH Users Help <freeswitch-users(a)lists.freeswitch.org> Sent: Sat Aug 14 11:19:07 2010 Subject: [Freeswitch-users] Strange early media SDP behavior Late negotiation is on, bypass_media=true.

Limits on number of concurrent registered users?
by Fabio Pietrosanti (naif) 14 Aug '10

14 Aug '10

Hi all, i am preparing a setup where i would have a huge number of connected users via SIP/TLS . The amount of concurrent calls will not be such high. However he amount of concurrently registered users could be even of 15.000 . Are there some specific internal design/architectural limits of FreeSWITCH on the number of concurrent users? Fabio p.s. we'll try to do some stress testing next week

speak in play_and_get_digits

Hi, in uuid_broadcast, all the following forms work: xxxx.wav a wav file phrase:demo_ivr_main_menu phrase macro speak:hello in play_and_get_digits, speak doesn't work. I know that I could put the actual text into a macro, however, a speak version would be much more clear, especially for demo. EXECUTE portaudio/0000000000 play_and_get_digits(1 9 3 5000 # speak:'flite|kal|please input some digits, end with #' none x_cc_dtmf .*) 2010-08-14 20:00:05.680230 [ERR] mod_native_file.c:74 Error opening /usr/local/freeswitch/sounds/en/us/callie/speak:flite|kal|please input some digits, end with #.L16 Is there any other way to get it work? Or should I report a bug or request a new feature? Thanks. -- Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn

mod_skypopen (skype endpoint) changes, please test
by Giovanni Maruzzelli 13 Aug '10

13 Aug '10

Hi FreeSWITCHers, I've made some long due modifications to mod_skypopen, that maybe introduced bugs. Please test with the latest git and report any *new* problem (ok, old problems too), here in the mailing list, or - much better - in the Jira. ========= commit 45c6c4d3e42e3c114b47d52ca2e9fca6b1be8090 Author: Giovanni Maruzzelli <gmaruzz(a)gmail.com> Date: Fri Aug 13 16:19:20 2010 -0500 skypopen: now answer a call only when directed to do it (before was trying to answer any incoming call). Lot of changes to a messy part, so maybe some problem will come out... Signed-off-by: Giovanni Maruzzelli <gmaruzz(a)gmail.com> =========== Thank you to all, -giovanni -- Sincerely, Giovanni Maruzzelli Cell : +39-347-2665618

Audio quesion
by Marshall Harrison 13 Aug '10

13 Aug '10

I have FreeSWITCH setup to answer calls on port 5080. If I have 2 simultaneous calls are both going over port 5080 or is that just listening port and the calls get routed to a different port? What port is the audio going over? 5080? A different port for each call? Thanks.

CentOS 5.x and Python 2.6: segmentation fault importing ESL
by Neil Patel 13 Aug '10

13 Aug '10

Hi All, I am using Python 2.6 on my CentOS installation, installed in parallel to the standard Python 2.4. I've compiled FS's python ESL module using 'make pymod', but the ESL python module causes a segfault when I try to import it in Python 2.6 (imports fine in 2.4). I'm guessing this is because the ESL module was compiled for Python 2.4. How do I change the ESL config/makefiles to compile for 2.6? I'm not familiar with SWIG, is there some configuration I need to change with it to use python2.6 executable? Thanks, Neil
