I have to design a network with SIP provider and PBX system.
All calls are routed via Windstream using the phone system gateway.
Now we want to set call routing in such a way that internet calls to rest of the offices are routed via Cisco 2911 & ATT
Now Cisco 2921 will be doing all the routing , but it has a default gateway for ATT , which will allow the phone system to see rest of the phone systems available on MPLS but how will they route the outbound call using the SIP provider Windstream.
I have attached a pdf showing current design and proposed. Can anyone help me out with that
