We have 3 sites. The Call manager is at the Buffalo Head quarters. Each site has their own PRI's. The NJ and MD have 1 T1 cas. The nY gateway has 3 T1 Cas. When the carrier changes the T1 Cas to a T1 Pri, do I change the config only on the Voice Gateways or also on the Call manager?? If we have to change things on the Voice Gateway, what should my changes be to accomidate the T1 Cas. Below is the info from the carrier. Also attached is the configs at each site.
"The circuits are being changed to ISDN PRI, with signaling set to ESF/B8ZS the hunting is ascending and the trunk groups are to remain the same as they are now."
Any assistance will be appreciated.
