871 to uc520

We are trying to re establish our remote site vpn +voip phone to our uc520 following IOS upgrade.  Can anyone point us to a link?  The 871 does not appear to be supported under CCA.  Previoulsy configured using cli, but this code is no longer recognized following Uc upgrade.

IOS 15 is following a new model where you need to "activate" its features.

Re: 871 to uc520

What are you trying to do? Replace the 871 with a UC520?

NO.  I am sorry I must not have been clear in the description. 

Our UC520 (main office) was upgraded to the latest ios,  firmaware. Is it now working with many added features.  However, when we did this our existing tunnel to a remote extention went down and we have not been able to get them to reconnect.  No phone ,  No vpn to our internal network, nor internet from the remote location.  Same cable ISP.  Same 7900 series phone,  Same 871 Router.  Probably some CLI config needed on the uc520  or the 871 or both.  But we have been spinning our wheels for bout a week.  We can see the 871 trying to negotiate a connection.

Ok. So you have an 871 on one end and a UC520 on the other end.  After an upgrade of the UC520's IOS, the VPN tunnel ceased to work.

What is the version of IOS running on both devices?
