Hi, I'm trying to get asterisk running on kernel 2.4.20 however trawling through the archives I've found a few references to patches to remove i4l's dtmf detection, but have been unable to find the patch itself (I think it is isdn_audio.c). Can anyone point me in the right direction? The problem I'm seeing is connecting a SIP softphone (tried a few) to an external number via an

...n of asterisk, and I'm experiencing hangups during voice conversation. This happens quite regularely and often. The problem is in dsp.c, line 1235, where it says accum /= len; But `len', at this point, is 0, resulting in a SIGFPE. The routine ast_frame *i4l_read() in channels/chan_modem_i4l.c:411 is setting p->fr.datalen to p->obuflen which is zero. Has anybody noticed this, too? Since I don't know the code, I cannot suggest a fix, but maybe someone who does is listening? :) For testing purposes, I changed the source line to if (len) accum /= len; Manfred #0...

Hi All, Something really weird is going on. I just stopped and started my asterisk server, and it just decided to stop starting.

Hi, I have a 1.2.4 * box with two HFC modems using chan_modem_i4l and several SIP phones and ATA's. We have a terrible delay on calls between the PSTN (isdn BRI) and the SIP phones. All internal calls are fine. My first thought was that the transcoding could cause the delay but all of the SIP phones default to ulaw so there should not be any transcodin...

Hi all, i have noticed that i can't hear a ring tone if i make a call from my TDM40B to a chan_modem_i4l endpoint. I had a look in the code from chan_modem_i4l and there is a function calling "i4l_handle_escape" that gives a AST_CONTROL_RINGING frame back. But this seems not work ...(or i4l is not signaling it ?)

Hi, i have a debian-system with the asterisk 1:0.9-1 packages and chan-capi 0.3.1-2 installed. My chan-capi seems to be out-of-order. Capi and I4l work in general. I can use isdnlog and capi4hylafax. Using chan_modem_i4l with the sam context work fine too. But no incoming calls are answered by asterisk over chan-capi. If have 2 isdn-card: a passive avm a1 (i4l/hisax) and a active avm b1 (capi). I also tried the 1.0-1 asterisk packages from debian testing. Please help Bye

...t work (and never has), but there has been an annoying problem with false dtmf detection in calls (that could be triggered easily by blowing into the receiver on the remote end). I looked through the list and found two patches that need to be applied - 1 to isdn_tty.c in the kernel, and another to chan_modem_i4l.c in Asterisk. This morning (and I say morning - because it's now 4:50am Friday here) I was feeling adventurous, so I applied the patches and recompiled my kernel. Once that was done, I started up Asterisk and noticed that there was no false DTMF (well - no dtmf was detected at all). Time for...

I've been working on a fixed point mec3 echo can. The old "mec3" which crashed a lot of peoples machines because it was floating point in the kernel is now available as "mec3-float.h". I'd appreciate any testing / feedback on the new fixed point mec3 echo can. Thanks! Mark
