[Asterisk-Users] drop calls with T100P / PRI

[John Brown (CV)]

Hi List,

a number of our customers are reporting dropped calls.

here is the config.

1   T100P  T1 Card
1   Asterisk  (Mid Nov build)

T1 is signalled as a PRI(National)

The card will only sync up if we clock, if
we line side clock the card goes into yellow alarm
and won't sync up.

the only errors we see are framing slips.

Around 2500 slips over a 18 hour period.
(this was reported from our T-Berd)


Any thoughts ???
