My call flow is
sip provide ----- CUBE -------MS teams voice
I have enabled "media bypass". everything is working fine.
Plan for media bypass with Direct Routing - Microsoft Teams | Microsoft Learn
The document said we can block some of the external ip by the firewall. (I am thinking to block external ip)
Then, the MS teams voice will use non-media by pass call flow.
However, it doesn't work.
Based on the integration guide from Cisco.
with media bypass and without media bypass, the sip profile configuration has a little bit difference.
I suspect it is the rootcause.
Direct Routing for Microsoft Phone System with Cisco Unified Border Element (CUBE)
May I know anyone has experience on it?
Can we make internal user using media bypass, external user not using media bypass?
