[Asterisk-Users] Re: E1 yellow alarms

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
