Hi,
I currently use? Asterisk 1.0.7-BRIstuffed-0.2.0-RC7k on a debian sarge
with a kernel 2.4.27 on a P4 3Gig with 1Gig
of memory
When i use i4l on any call, the called party ( on the telco operator
side ) ear me with a delay of 1 sec after 1
minutes , 2 sec after 3 minutes and so on...
After a quart hour, the delay make the conversation just impossible !!!
I use a tdm400P to connect my analogs phones and all is working very
well between two zap stations.
I have tried different Passive isdn card ( no hfc so I can't use
zaphfc driver)
Anybody have an idea to fix this problem ?
BTW, I have compiled my kernel with the dtmf patch for isdn_tty.c so....
The cpu usage is 25% during a conversation, 75% idle
I have a PCI latency of 32 msec
With or without APIC, no changes....
It seems that the voice is buffered and sended too slowly to the i4l
channel and so a delay is present afetr a short
time and became bigger minutes after minutes...

I had the same problem with i4l.
It seems to be a driver problem. I think i4l is depricated for a reason in
the newer Asterisk versions.
Funny thing is: When I switch the remote users into a MeetMe room. And have
the local users dial in to the same meetme room.
Then the problem disappears (at least for me).
I don't know how or why this is. But it is my experience. I am not using i4l
anymore.

Why don't you use mISDN? Armin
