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.
please provide us with some more technical details, like a network diagram, specifically details on the path that you are having problems with. I dont think it is a good idea to assume "asynchronous routing" (BTW you probably mean asymmetric routing were a traffic flow uses different paths to and from a destination), is an issue. It is better to have an open mind and diagnose your problem with the information that you can gather. thanks

If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
