We currently have a client that has a 7970 phone that's attached to a 871W using ezVPN to establish the VPN connection back to the Call Manager. He wants to move from Time Warner Cable to AT&T's U-verse.
The questions are:
1. Can this setup work with AT&T's U-verse. I don't know much about it.
2. If so will I need to reconfigure how the 871W establish's the VPN connection?
Below are the configurations on the 871 that matters:
------------------------------------------------------------------------------------------------------------------------------
crypto ipsec client ezvpn **VPN Name**
connect auto
group **VPN Name**Group1 key **KEY**
mode client
peer **IP Address**
acl 100
username **Username** password **Password**
xauth userid mode local
interface FastEthernet4
ip address dhcp
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
ip nat outside
ip virtual-reassembly
no ip route-cache cef
duplex auto
speed auto
no cdp enable
crypto ipsec client ezvpn **VPN Name**
interface BVI2
description ***VPN Name**-VOIP-Interface*
ip address 10.10.11.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
ip nat inside
ip virtual-reassembly
crypto ipsec client ezvpn **VPN Name** inside

Thanks in advance for any assistance.
