Realtime graphing is not supported, but this tool happens to be
UNIX-based and parseable by other upstream systems (like RRDTool or

I have put iLBC at the top
I want use iLBC and have following in mind, please help me is it possible ?
ISDN <-----(ALAW)-----> * <-----(ALAW)-----> SNOM
SIP??<-----(iLBC)----->?*?<-----(ALAW)----->?SNOM
1. ISDN incoming codec is ALAW SNOM codec should be ALAW (can't be iLBC
because a lack of codec).
2. SIP incoming codec should be iLBC (snom is ALAW).
3. SIP outgoing codec should be iLBC /snom

best low-bandwidth strategy
Hi,
To push voice through a long thin wan (dsl) there are two choices:
(1) have the cisco's (7912G) talk g729a to each other (reinvite=yes), or
(2) have the cisco's talk to their local * in ulaw (reinvite=no), which
talk to each other through a more advanced low-bandwidth codec (ilbc or
speex)
which is best? (2) would have more latency, wouldn't it?
Did I miss a third option?

Speex or iLBC?
Hi kind developers,
I need select soon the best freeware VOIP codec, I see that all competitors
are using iLBC because of the separate packets management.
How speex behave in case of packets drop?
Why other choice all iLBC?
Thank you for any kind answer.
Best regards.

what is the best codec for low bandwidth? for quality?
The number of codecs is overwhelming to me.
What do ya'll consider the best codec for conserving bandwidth? [I realize
at the cost of quality]
Secondly, what do you think the best codec for voice quality is?

speex, ilbc and g729 codecs, GSM with IAX
Dears;
I do not know if any had experience in using speex or
ilbc with IAX and got good results, because I am
facing a problem with GSM.
I am facing a noise problem when I am using GSM with
IAX trunk as following:
IP Phone (G711) ---> Local Asterisk Box ---> IAX Trunk
using GSM codec ---> Remote Asterisk Box ---> Digium
Card (FXO) to terminate the call to the destination

super high bandwidth codec
I've just gotten off a skype conference call and it pisses me off that
the quality of skype is higher than my asterisk calls.
Is there such a thing as a super high bandwidth codec?
In a situation that you have the bandwidth to share is there something
that I can use for important calls when the situation warrants it?
TIA,
Dean

Unable to find a codec translation path from ilbc to ulaw
Hi!
As the upstream of my DSL-connection is very slow, I'd like my
sip-phones to use iLBC to connect to my *. My gateway provider only
allows ulaw. Hence, I'd like to use the follwing setup:
SIP-phone <--iLBC--> Asterisk <---ulaw----> PSTN-Gateway
I get the following error:
"Unable to find a codec translation path from ilbc to ulaw"

iLBC re-licence
Does anybody know if the updated licence on iLBC makes it safe to
include in Asterisk when used in a commercial environment again?
https://sites.google.com/site/webrtc/ilbc-freeware
It seems to require that the Google iLBC licence document is on the
box, but that otherwise it is free-to use by all in any way (BSD
licence style). I believe that prior to that there was a requirement
to register

GSM to iLBC one way audio :-(
Hi,
I'm using IAXphone for remote users which limits me to the GSM codec.
Internally I limit the SIP phones to iLBC codec (GS 101 1.0.5.0)
I also use voiptalk.org for external PSTN access again using the iLBC codec.
The problem I have is that when the IAXphone dials an internal phone or PSTN number either the line hangs up immediately or there is only one way audio from IAXphone.
It works

iLBC issue: An ilbc frame that isn't a multiple of 50 bytes long from RTP (38)
Hello all,
I've started implementing iLBC on some of the ATAs we have floating around
clients' homes, but I'm coming against this error message with most of them:
codec_ilbc.c: Huh? An ilbc frame that isn't a multiple of 50 bytes long
from RTP (38)?
The ATAs in question are various Grandstream models - the HT486 being the
predominant one. Looking at the list archives, it's

Will there be any support for iLBC in IAXClients soon?
Hello Folks,
I noticed that all of the IaxClient based softphones with exception of
Firefly only seem to have support for GSM but what about iLBC?
The quality is excellent with iLBC even on a dialup connection! Meanwhile
while the audio on GSM often sounds scratchy. Is anyone looking to
implement iLBC in an IaxClient based softphone soon?

Are there any hard phones that support ILBC?
I see lots of soft phones but not Cisco, Polycom etc.
