Description (partial)

Symptom:
Jabber Mac 11.9.2 does not send media/RTP over phsyical interface after VPN even after _collab-edge._tls.<domain> is resolved (_cisco-uds._tcp.<domain> not resolved)

Steps to reproduce:
----------------------------
1. Establish Anyconnect VPN on Mac
2. Using _collab-edge._tls.<domain> Jabber discovers expressway-e and connects to expressway
3. Jabber using VPN interface for Audio RTP traffic
4. Expected behavior is traffic should be sent over public network instead of VPN because customer's VPN tunnel have low bandwidth for moving media traffic

Jabber 11.8 Mac do not take VPN interface as priority thus media traffic does go over physical interface (public network)

Conditions:
Use Jabber for Mac 11.9.x
Media traffic is blocked over VPN
