Asterisk SS7 link dropping

Hi all,

I am using asterisk 1.6,Dahdi,libss7 and sangoma card for ss7 e1 lines. I have 16E1’s connected to one server.

I have a outbound dialer. Every two hours approximately the ss7 link is dropping and i am getting the following messages on the CLI when ever this happens

Hi

We are also facing the same issue. how were u able to resolve the issue…

Pls help…

Thanks
Saurabh

Could any one solve this issue? is it related with IRQ’s? is there anyway to sync the clocking without a timing cable preferably an E1 connected with port 1 card 1 to port 1 card 2… ?

hi:
please show the cat IRQ and check the status from service provider.

It worked when I used Asterisk 1.6 and chan_ss7 with 64 bit OS. 16 links are stable. [sorry for the long delayed reply :smile: )
