This week we had a customer (Dave) upgrade his client's Norstar MICS from R5.0 to R7.0 XC. Dave used a R6.1 XC software card as an intermediate upgrade, in essence the upgrade tool. Then he upgraded to R7.0 XC with no problems . . . except one.
Dave's client had a PRI with multiple DID numbers. All of the DID's would return stutter dialtone when called. Auto DN and DISA DN were set to none.
I finally had Dave change the PRI in hardware settings to T1, and then back to PRI. This purged the programming bug and allowed all of the DID's to ring to the correct extensions. Dave did have to rebuild his PRI routes, but all is now operating correctly.
My thanks to Dave for reporting back to me what he did to fix the problem.
So if you experience odd problems with a PRI after upgrading the software you might be able to solve the problem by changing the hardware type to T1 and back to PRI. Be sure to make note of your route programming in case this procedure wipes it out. - Brian Cox
