Answering myself, it seems I was incorrect, as jbenable is enough to
activate the buffers. I see the options different meanings now. Sorry about

Hello!
I am going to use the JITTERBUFFER function in a SIP (and local channels)

1. Do I need to activate jbenable in sip.conf? Or is it enough to call
the JITTERBUFFER function?
2. What is the preferred way to invoke this

What is the consensus on using the 1.4 jitterbuffer? Do most people

We have a "PSTN" server that has our RBS T1 trunks in a central location,
then have clients that connect via SIP to us for access to those trunks.
Most of them are just fine, but lately we have a handful that are h

Hi, I have a question about jitterbuffer and PLC.
I use Asterisk 1.6.2.0 and 1.6.0.20 or older.
I use uLaw.
My system map:
=
[ asterisk 2 ] -- # LOSS # -- # A # -- [ asterisk 1 ] -- # B # -- [ X-lite ]
It's long gone.

In 1.2 and 1.0 there is no jitter buffer for SIP. I think 1.4 might
have a SIP jitter buffer, but I'm not sure. Check sip.conf.sample in 1.4.

but keep in mind, that jb for sip (generic jitterbuffer) is implemented
differently, than iax, so it works only for SIP-SIP calls, or SIP-ZAP

I know, that jitterbuffer should be set at receiving side and on
outgoing call leg,
ie. if sipphone calls to asterisk and outgoing to zap chanel, I should
set jitterbuffer on zap channel (to dejjitter audio stream from sipphone)

Thank You Patrick,After some minor problems in some file paths I had success compiling.The only problem was the codec_g726 witch does an illegal call and Asterisk doesn´t come up. But I only use g729 or g723 so I´ve deleted it from the modules directory and asterisk came up.

What you have above is part of 2 separate conversations.
You have the tail end of a successful registration with 70.87.18.51

Hi there
I have users that are using IAX clients, dialling into
meetme conferences. They will be on varying connection speeds. Firstly, should
jitterbuffer be used with meetme? Secondly, I have read some posts which
indicate that jitterbuffer is not that stable. Is it stable enough to use?
