I am looking to set up a Cisco IP phone at a remote L2L VPN site (192.168.50.0/24) to connect into our CME 4.3 system at our main office.
At present our Voice Network is using VAN10 with network 192.168.100.0/24 and our DATA network uses 10.0.0.0/24 on the Native VLAN.
Data Users have the Layer 3 switch (10.0.0.1) as their default Gateway so they can access the CME 192.168.100.0 Voice Network, similarly CME system uses the same Switch on VLAN20 as a default gateway on IP address 192.168.100.1, outgoing Internet is passed onto our Cisco ASA (10.0.0.2)
Can anybody tell me the steps involved in getting a remote IP phone up and running?
As far as I understand that I will just need to add the CME Server IP address as a DHCP option at the remote site and also add NAT Exemptions and Interesting traffic access lists for the VPN connection, is this correct?
