HCS deployment over DMVPN

Hopefully I've selected the right community to post this in.

We have a customer to whom we will be supplying a DMPVN based encrypted WAN and our HCS based unified communications product.

I understand that it is often necessary to put voice into a 2nd encryption domain to avoid anti-replay problems on the data services. Easy enough with IP phones that would go on a dedicated voice VLAN but how about Jabber where the media will be sourced on the data VLAN?

We are thinking about using PBR to match on RTP ports and push it to the voice encryption domain.

Does anyone have any experience of this or have any recommendations?

Thanks

Hello.

Hello.

Max anti-replay window supported is 1024.

So, I wonder what is your branch WAN/voice bandwidth, that you need dedicated encryption domain for voice?
