Yes - the problem was a missing signalling line in zapata.conf. Now in and out work. Also, it was news that "reload" from the console doesn't reflect changes made in zaptel and zapata.conf entries. Any other config files that it doesn't reload? >From: "Asterisk@Home" <asteriskathome@yahoo.com> > >Did you go into AMP and configure some place for

Hello, Can you please tell me what the overload point is for OPUS in dBm0 or dBV? As an example, the G.711 A law codec has an overload point of +3.14 dBm0 across a 600 ohm circuit. In ITU-T G.100.1 section 5.8 you can read more about the relationship between dBm0 and dBov. In that same section you can see that the G.711 A law, u law, and G.722 codec overload points are also defined.

Hello, I need to convert the dahdi_monitor output to dBm0, so I can measure Echo Return Loss in dB. I've read a formula that calculate S(k) in ITU-T G.168 recommendation, where S(k) is the signal level in dBm0. Can I use this formula to convert it? If yes, what value should I use to the number of samples if I want to convert a single output from dahdi_monitor? -- Thanks in advance, Gustavo

Hi Marc, It's not exactly clear how to define the an "overload point" for Opus. In normal use, it's not a good idea to go beyond the +/- 32767 values for 16-bit PCM or +/- 1.0 for float. That being said, internally Opus can represent signals that are up to about 48 dB louder than the PCM saturation point and if you use the float implementation you can actually encode and decode

I have some questions about how a sample is encoded in Vorbis regarding the dynamic range. I try to figured it out by reading the Vorbis spec and I failed. But I found this quote from Monty: ?Vorbis, BTW, can handle, for sake of programming simplicity, >200dB range. Just for kicks.? [1] It's still unclear to me what that means. Should I think of Vorbis as a floating-point format or a

I'm trying to find a way to generate an 'internal extensions' tonelist but I can't seem to find anything on how to do this. My idea was to start a Playtones(intercom) tonelist and not indicate ringing to the line (dead air). But then, somehow StopPlayTones needs to be run once the ringing telephone picks up. This seems like a dirty way to do this. I envision an option to the

Is there a configuration difference for clone X100P cards versus "compatible"? I have a similar problem to what David Shaw posted earlier today. 0.5 installed OK, but mine just with one X100P clone. Default config files, edited zapata.conf per the FAQs so it includes the line channel => 1 without the semicolon. Any outgoing call attempt returns "all circuits are busy"

Hi Jean-Marc, dBFS means dB relative to digital full scale. In other words: a sine value of -42 dBFS will, on a 16 bit PCM signal, swing between 131 and -131 only (16384 * 10^(-42/20)) So we are far below +/-8000. At the moment, I'm out of ideas how to debug systematically. That even very small rounding errors alter pitch values fundamentally makes the situation worse for me, because it

First, THANKS! The SYSLINUX/PXELINUX s/w and docs are great. I have been able to set up a working server for PXE boot in very little time, using our existing Win2k DHCP server and a Red Hat 7.2 Linux server for tftp, etc... It took very little time (compared to an earlier effort 4 months ago.....) and the pxelinux/menu/memdisk environment is great for us. The environment seems to support PXE

Hi, I'm quite sure we found a bug inside the codec (1.2rc1, wideband mode). It only occurs when speex is compiled with the FIXED_POINT flag. I feed in a 2000 Hz sine wave (-15 dBFS). When I simulate a single frame loss (i.e. pass a null pointer to speex_decode_int as second parameter for just one frame), the decoder starts to freak out a second later: It produces horrible noise with 0 dBFS.

An update: I found that the "ADD32: output is not int:" messages are caused by the enhancer. When I turn the enhancer off, the messages vanish, but the "freak out" of the codec is still there - so the problem seems not to be related to the overflow messages. best regards, Frank ---------- Urspr?ngliche Nachricht ---------- Von: Frank Lorenz <Frank_wtal at web.de> An:

Full_Name: Richard Short Version: 2.9.1 OS: Windows XP Submission from: (NULL) (98.225.76.171) I'm having a problem in R that may be an operating system problem. I'm getting an error message that reads, "Too many files open". I'm opening files and closing them (and unlinking them), but when I go through that process 509 times, the program bombs and I get this error message.

Hi Jean-Marc, all, I didn't get any response to my issue up to now and would like to now if anyone can reproduce this behaviour and if there is some idea what happens. I am willing to fix this issue, but because I do not know the internals of speex, I need some advice on how to proceed... best regards, Frank Frank Lorenz <Frank_wtal at web.de> hat am 21.

Hi Frank, Sorry, I *do* care about the problem and just happen to be overworked at the moment. What I suspect is that the pitch gain gets close enough to unity that the loss makes it bust. Did you test with the floating-point code? Jean-Marc On 2010-01-13 03:45, Frank Lorenz wrote: > Hi, > > is no one willing to spent some effort on this topic? At least it would > be good >

Hi, app_milliwatt is a nice tool for a quick check of the line quality. Anyway, hearing to that tone for more than a minute is painful. Does anyone know the "opposite" application, i.e. an application, that "hears" and listens for a 1000 Hz tone and displays the quality in any unit? If not, I'll think about developing one. Regards, Roger.
