Coral, thanks for the reply.

There is no MPLS, all sites are connected via a VPN. Voice quality is really not an issue here. QOS is enabled to grant voice traffic highest priority, however, we all know we are at the mercy of the internet with no PTP or MPLS in place. This has NEVER been an issue in the past, every now and again the VPN may have needed to be reset, but only when calling from site to site was down. Site to site works just fine, the corporate location can hear all the remotes sites just fine with no interruptions, only the remotes sites are complaining that every other word is being cut off. That said, the call NEVER drops, it stays connected.
