I had the exact same problem while installing a PRI yesterday. What I
did was changing to letting the telco handle the timing( digit nr. 2 in
span). However that didn't do the trick until I ran ztcfg -s and then
ztcfg, and then the PRI resynced and has been fine since then. However
it could be something else in your case, but I hope this helps someone.
Regards,
Maron
