I have Cisco umbrella and redundant VAs for forwarding. I have 2 internal domains and have the VAs set to send DNS requests for domain abc.net to 2 domain controllers in that domain. I have DNS requests for domain xyz.com set to go to 2 other domain ...
I have set up multi-tenant in my Cisco CUBE. I needed to direct sip sessions on different interfaces. My question is, can I establish an ip address trusted list for each tenant or does it always reference the global voice service voip configuration? ...
I've been working all week to get unified messaging working again. We had is setup with our on-premise exchange server 2013. We migrated to Office365 and I created a new Unified Messaging service and followed the documentation to set it up. I created...
I'm converting from on premise Exchange to O365 and following the documentation here: https://www.cisco.com/c/en/us/support/docs/security/cloud-email-security/214812-configuring-office-365-microsoft-with.html#toc-hId-1043986565Where i'm stuck is conf...

@Nithin Eluvathingal I tried using the sho ip address trusted list to see the dynamic entries from the dial peers. That doesn't seem to work. Also, the provider is a dns entry using sip-server command on the tenant. I don't know if that affects how i...
Wow, just when you think you've learned something, you realize how little you know! I previously had dial peers setup on my old router (it is using PRI to PSTN) so that there was a different dial peer for every direction and every numbering plan. The...
@Roger Kallberg that is exactly what I have done. I am using a VRF for the outside interface with only routes to the service provider. The inside interface is in the global routing table. I used tenants for each dial peer so I could bind the sip sess...
