I have been getting mixed information about asynchronous routing and VOIP phones having problems. Our network is redundant everything. Dual WAN circuits, dual routers, switches, etc. And running a dynamic routing protocol you will inevitably have asynchronous routing. We have a couple hundred phones traversing this network and others through firewalls to get to the PBX/Gateways, other phones, remote gateways, etc. It has been like this for a few years with 95% of the time no issues. Rarely we have the dropped call and static issues. When we do have those issues I hear "asynchronous routing" is the culprit. I need some guidance and verification of what I need to look at or disregard when encoutering this.
Thanks
Doug
