Hi,
Does enabling a jitter buffer in sip.conf make sense if the call is pure SIP?
SIP client---ASTERISK SIP---Internet SIP provider
I think it should help on the Asterisk receiving side in case of unreliable
bandwidth.

Why don't you just ask Google? Gives tons of answers:

The jitter buffer config can be found in sip.conf

There is a theory that says that jitter buffers should not be used until
the end of the voice path where jitter might be introduced. With that in
mind, and in this scenario, the jitter buffers should reside at the ATA
and media gateway;

All of the timing information should be passed across the bridge in all of the
frames that come in over RTP. I can't say I verified this with packet
captures,
but I did look for this in

Thanks a bunch. So in theory the media gateway at the far end should be
able to properly jitter buffer the entire RTP path from the ATA via
asterisk, correct?
Would this be the same in 1.2 and it 1.4?
Yes, that is correct, but only for 1.4. In the case of Asterisk 1.2,

I did find the jitter buffer patch on the bug-tracker...(ast_jb-1.2.0.patch4).
I applied it to a 1.2.6 asterisk and it seemed to apply all but 2 small
chunks (which I was able to apply myself)... it then compiled... so I'm
going to give it a shot and test it out. I will report back results.

Hi,
I am keen to try out the SIP jitter buffer capability. I hear this was
available if HEAD.
I was wondering if a version of the latest STABLE with this additional
feature was available some place.. Or is it simply best to use HEAD?
Would some one be kind enough to point me in the right
AFAIK, it's only available in Head.

Hello,
Is there anyone using sip jitter buffer with callingcard application? it
seems like there is a memory leak that dosent let the app_prepaid_call to
insert acc_start informations in database and send the call so the
asterisk segfaults.

I really want to start using 1.2.5, but I also really need to have the

Hi
I am using CVS latest
Is it correct there is no jitter buffer for SIP (RTP)
Are there any plans for this?
prob a stupid question:
Is it required / do the endpoints handle this - if the
src and destination are both SIP and there is no
transcoding but asterisk is still in the media path?

It's planned to do a unified jitter buffer. But I haven't managed to find
the focussed time so far to get it done.
