Your 16th channel may be mismatched with the network.  Timeslot 16
is usually used for signaling.  channels => 1-15,17

Hi Richard,

The link is up on 16 th channel. My objective is to have 16 E1 to be configure
on single machine with two 8 port sangoma card. Which is problem I am facing.
Please let me know if you have any solution.

Thanks
Vinod dharashive

Hi vinod,

i have never tried to put two A108 cards into one server but it sounds
like an IRQ Problem to me. you should check all system relevant
information (lsmod, lspci,dmesg) if you can see any kernel errors with this.

it could also be a span identification problem that chan_dahdi recognize
the second card also beginning with span 1 and not 9 or something like this.


btw i dont think that you will be happy with asterisk 1.6 and handling
496 concurrent calls over ss7

best regards

Stefan

Sounds like it could be a clocking issue between the two cards then.
Everything needs to use the same clock source.

Can u please share with me.

Hi Richard,

Thanks for reply, how can I identify clocking issues on card. Manually calls
goes successfully on both the card. After 10 min signaling  links goes down.

Hi Patrick,

I did that, sangoma does not support Libss7 stack and they mentioned that Libss7
does work right with sangoma card with 16 e1.

Since you have a Sangoma card why don't you ask Sangoma support instead 
of asking Digium?
