Hello,
First and foremost, I shall like to thank guys at Sifra to make
chan_ss7 possible.
interesting I found that while using chan_ss7.0.9.tar.gz, my calls
never seem to get established and i used to get crazy kind of errors
like

and my links never used to come up, I have already put the right opc
and dpc codes. And that was the story while i used chan_ss7-0.9.tar.gz,
after which i thought to degrade to chan_ss7-0.8.4.tar.gz, and voila,
my calls started maturing, but still, I keep on seeing the following on
CLI ALL the while

And after some time, my ss7 link goes down automatically for some crazy
reason, and i need to stop and start asterisk, and the links come up,
but still i keep on getting the MTP2 CRC Error flooding my CLI screen
and the log.
when ss7 link goes down, it shows Blocked Remote Hardware, the guys on
the Switch end say that my machine is sending too much of negative
slips (its a Nokia MSC)
I would like to know if any one faced this, i also surfed through
archives, but that issue was pertaining to some IRQ issues but my
machine has seperate IRQ for my TE110P card.
