Solved: Options: Satellite Office IP Phones Need WAN Access to UC520W

srcasella · ‎08-20-2010

We have a UC520W-8U-4FXO-K9 in our main office and are opening a small satellite office. Two phones are needed in the satellite office and we want them to utilize the UC520W in the main office.

Which Cisco product is recommended to enable two Cisco IP Phones to access the main office UC520W?

Is there a Cisco IP Phone which has all of the necessary software installed and does not require a VPN site-to-site tunnel or Phone Proxy?

Our default plan has been to deploy a small 520 Series Secure Router or 871 Dual Ethernet Security Router in the satellite office and configure a VPN site-to-site tunnel. Is this necessary with the current Cisco IP Phone models?

Thank you.

The remote teleworker router is the SR520 Ethernet version or the 871 ISR, supporting up to 4 phones without a switch. 5 actual teleworker phones per site allowed. UC540 supports 10, UC560 supports 20 such routers with VPN tunnels.

The SPA525G has a built in SSL VPN connection capability for voice only (no tethered PC on the phone).
