UC520 VOIP over Internet

Hi,

I have an employee in another state that I would like to be a part of our phone system.  Our phone system is UC520.  The employee has a Cisco IP Phone Model Number CP-7940G.  I would like to be able to dial an extension and reach that phone. 

How can I get this phone to be a part of our phone system? 

Thanks,

VPN.  The UC520 has VPN capability and licenses included.  You wil need to install something at the remote site such asa  Cisco871.  Configure a tunnel and then you can use your phone at the remote site.  Another potentialy easier and cheaper solution would be to use CIPC softphone for the remote site.

Re: UC520 VOIP over Internet

The user in the other state has a D-Link DIR615 and it is L2TP capable. Are there any specifics we need to do in order to establish a connection to the UC520?

Re: UC520 VOIP over Internet

I don't know about l2tp.  I would tend to think IPSEC would be the best way to go.  You will need to read up on how to create an IPSEC tunnel for the Cisco and D-Link and get that configured and tested.

A Google search for "uc520 ipsec tunnel configuration" should get you started and then similar for the D-Link side.

One search reult I looked at mentioned that this is not be officially supported by Cisco, so keep that in mind.
