RE: nodebytes and leafwords
hi kuhlen,
what you said is correct. i am talking about how
you are going to arrange these codewords into an
array, i.e. in the function _make_decode_table.
there he uses node bytes and leaf words for memory
management. i got a 24 bit platform. so if i assume
that max. codeword length that could be possible as
24 bits can i allocate a memory of (2 * used entries - 2),
to arrange the whole tree in

RTP not being switched between both SIP endpoints
We have a system where calls are coming in from telcos via an opensips
server and then being redirected out to a regular sip destination.
There is no NAT, DTMF features, call recording, or codec translation
being performed so I would expect asterisk to issue a reinvite after the
call is answered and switch the audio however it is not happening.
Here is the sip peer information for the call

Negotiates g729 but RTP contains g711
Hi,
I was able to use Unsniff to validate that the incoming 20 byte payloads of audio from the downstream IAX2 trunk was definitely G.729a whilst Asterisk 16.13.0 transcodes to G.711a unnecessarily. Media is confirmed as having been negotiated as g729 on all four streams. Nuance with this call is that it's from a WebRTC client which doesn't transmit any audio, could this be influencing

Here my comments:
Page 3:
To be compliant with this specification, implementations MUST support
8 kHz sampling rate (narrowband)" and SHOULD support 8 kbps bitrate.
The sampling rate MUST be 8, 16 or 32 kHz.
There is a type above after (narrowband), there is a " extra character.
I don't understand what is the motivation to specify "SHOULD support 8

RTP sent to internal IP
Hello List,
I need your advise please.
I am trying to establish a call from Asterisk 1.8.15-cert5 to one remote SIP
UA (not Asterisk), both are behind NAT. That remote peer is configured with
nat=yes in my sip.conf but yet RTP packets are being sent to its internal IP
address which is declared in the Connection Information (c) in the SDP,
obviously reaching nowhere. I need RTP to be sent to the

No IVR audio. Jump in RTP sequence number
My users dial *120 get to an IVR menu that plays their balance and then
ask them for a voucher. Ater the balance is played and the request for
the voucher is played the user don't hear any other audio from the
asterisk box. I can see the asterisk server playing the files to ask
for the voucher again but the user cannot hear any thing.

Comments on New RTP Profile Document
The latest revision of the draft profile for use of Speex in RTP
is attached. We plan on submitting this - or a modified version
of this, based on immediate feedback - to the IETF on Monday for
consideration at the next meeting.
Major differences in this revision are:
- removed the discussion in the MIME section. It's a duplicate
of the SDP discussion anyway, and may or may not match the

Huffman decompression
Hello !
A question to all 'Wheel-reinventers':
I can build the huffmantrees by hand (on paper)
but how to code it? Are there any good URLs
out there? Or does the spec supply sufficient information?
I tried figure out how oggdec (debugging) does this,
but I couldn't get the clou.
Thank you
Dominik

oggenc questions
Hello everybody!
Some questions concerning oggenc:
1 why is it called oggenc? (vorbisenc would make more sense)
2 Is it true, that oggenc uses only some predefined codebooks (depending on -q)?
2.1 Are they just "random" books, or were they "optimized" in any way
2.2 Is it possible, that some codebooks are stored in the header, but are never used (even in long (>3min) files)?

What's the purpose of the 'sr' sdp parameter ?
The sample rate is already given in the a=rtpmap line ?

First draft for Speex RTP profile - Please send your comments
Hi,
We'd like to announce the first draft for the Speex RTP profile. It was
written essentially by Greg Herlein, with some help from Simon Morlat
and I. We'd like to get some feedback on it before it is sent to the
IETF. Basically this will allow all SIP based VoIP applications using
Speex to inter-operate. For those interested, there's already Simon's
