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... Alain Degreffe
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
