Onec I have seen that someone was using Tunneling of VoIP/Encapsulation, so Telecom cannot find Q.931/H323 packets.
Could anyone help me to make this and what my Router should support (VPN, IPSec….)?
Is there any strange behaivor of GWs and is Voice quality the same?
Does it secure form TElecom network analyzer?
Could I make two Tunnel/VPN to two different ptoviders?
