> module show like chan_dahdi.so

Ah, i just see the warrnings (if i have many calls):

> module show like chan_dahdi.so
Module                         Description
 Use Count
chan_dahdi.so                  DAHDI Telephony w/PRI & SS7              184
1 modules loaded

It goes like that:

WARNING[10402] chan_dahdi.c: MTP2 link down (SLC 1)
WARNING[10402] chan_dahdi.c: MTP2 link down (SLC 0)
ERROR[10402] chan_dahdi.c: Alarm on link!

WARNING[13065] app_dial.c: Unable to forward voice frame

WARNING[10790] chan_dahdi.c: Duplicate IAM requested on CIC 89



So this is not very big traffic, but i think that zaptel/dahdi
interface is not fast enough to send/receive low-level SS7 messages.
i set:
mtp2=16
mtp2=47

So, mtp2 layer should be handled in kernel?

I've tested Sangoma cards, but hardhdlc looks like not working with
ss7 signaling.

any hints? Maybe i should use diffrent approach, like having two E1
spans with ss7 and two E1 links to DSS1 (EuroISDN), right now i've got
one card for SS7 (4 spans) and one card for DSS1 (also 4 spans)?
