SD-WAN - ISR4K Unified Communication

[Daniel Lucas]

I have seen where SD-WAN on ISR4K platforms has recently added Unified Communication support. Does someone have what limitations there are currently with this? I have a potential customer looking at SD-WAN, but uses UC features at all their branch WAN routers.

-Thanks

No one encountered this before? How are customers implementing this with Cisco voice routers? Using a separate dedicated router just for voice services?

Dear Daniel,
on the old versions, it was a limitation on E1 capability but on version 17.3.1, the E1 became supported.
Please check this release note

https://www.cisco.com/c/en/us/td/docs/routers/sdwan/release/notes/xe-17-3/sd-wan-rel-notes-xe-17-3.html

particularly in  Table 7. Supported Modules on Cisco 4000 Series Integrated Services Router

Thank you for your response,

What modules/interfaces are supported is important, but I am also looking for things like 'Only SIP phones' are supported, H323 is not supported, etc. I haven't been able to find any documentation listing these caveats - which make me hesitant to recommend going with this solution for customers who have Cisco voice routers at their branch locations.
