All, Having problems terminating to a Nuvox PRI, the tech at Nuvox is saying Asterisk is transmitting in CCITT (aka ITU?) when they're expecting (and will only accept) ANSI. The question is, is there a simple way to change this or am I stuck with rewriting code? I googled and checked the mailing list and found nothing, I could be barking up the wrong tree I guess. PRI is not my forte. Thanks, Matt

...e: >> Note that the channel order may not be defined. > > IMHO it doesn't matter in this place of documentation (which describes > default channel assignments for FLAC). Your proposed wording was: 0000-0111 : (number of independent channels)-1. The channel order follows SMPTE/ITU-R recommendations. The assignments are as follows: The channel order might not follow SMPTE/ITU-R recommendations, so this proposed wording seems misleading to me. >> So the WAVEFORMATEXTENSIBLE channel >> mask is saved ONLY when the channel order >> does not follow SMPTE/ITU-R...

There appears to be a disagreement between the encoding given in the sources for Siren14 that are downloaded from Polycom (and the ITU, both are the same) and that implemented by codec_siren14.so. The latter agrees with the actual device. If I make a .sln32 file and run the encoder from ITU/Polycom with encode 0 foo.sln32 foo.siren14 48000 14000 the resulting file doesn't play back correctly with the Digium's siren14...

Hi, The ITU has been churning out a series of codecs which stretch older codecs to support wideband or super wideband and stereo. Does anyone know of these things being used in the real world? They push the idea of these things offering high compatibility, as the narrowband bitstream is embedded in the wid...

Hi, Does anybody know where I can find any open source ITU G.107 implementation available? I'm looking a way to measure the voice quality in my projects..

Hi All, Could somebody explain me how the timestamps are computed in asterisk while bridging two sip channels ? I've got situation with my provider, who changed some things in config and added some codecs (that much i know) and after that we got one way audio issues. It seems that the problem is with RTP timestamps. Within one outgoing stream the RTP timestamps are growing, as it should be, but sometimes while the ast...

I have a long equation that I need to break in the R documentation of a package or it trails off the right hand side of the page. Here's the formula: \deqn{Cov(r_{ist}, r_{iuv})= [.5\rho_{ist}\rho_{iuv}(\rho_{isu}^2 + \rho_{isv}^2 + \rho_{itu}^2 + \rho_{itv}^2) + \rho_{isu}\rho_{itv}+ \rho_{isv}\rho_{itu}-(\rho_{ist}\rho_{isu}\rho_{isv} + \rho_{its}\rho_{itu}\rho_{itv}) + \rho_{ius}\rho_{iut}\rho_{iuv} + \rho_{ivs}\rho_{ivt}\rho_{ivu}]/n_i} How can I break the formula and optionally indent the second lower piece; though I'd settl...

...he draft goes into more detail as to why this decision was taken. <p>This was expected, but several people wanted us to ask. We did, they said no. So, we have to continue to define the out-of-band means to agree upon a codec, as we have been doing. There are discussions happening with the ITU (spearheaded by Roger Hardiman and the folks at Equivalence, who do the OpenH323 Project) regarding an agreed upon means in ITU-T recommendations H.323/H.245 to negotiate payload mappings. Roger has asked that we wait to update our draft profile until we get some answers back from the ITU. This i...

Sorry Martin to bother you again! I have an ISDN flux with 100 numbers. The local PSTN is sending now the DNIS/DID (so they said!!!) (I have set the immediate=no in zapata.conf) but I have the same problem as before : NOTE : the number is alphanumeric-DID alphanumeric (I will make tests with numeric mumber!).
