I have two Linksys RV042 VPN Routers in place; one at home, one at work.  I have them both setup and working great my VPN is connected 24x7 and I can access all network resources both directions.
We have Cisco Call Manager Setup at work and I have a 7961 Phone at home.

The phone is connected over the vpn.
I can check my voicemail, hear the unity messaging system, leave voice messages, etc.
I can make calls from the IP Phone, but I cannot hear the other end; they can hear me fine.  When I place a call I can hear the numbers being dialed but I don't even hear it ring....

Info from the phone itself....
                                IP  192.168.1.107 255.255.255.0
            Default Router  192.168.1.1
            Call Manager 1  172.31.1.1 Active
   Call Manager 2 SRST  172.31.1.253

Work Network       Work RV042        Call Manager Network    
  172.16.0.0           172.16.1.73               172.31.1.0

Home Network
192.168.1.0

The work network is an all cisco network with the exception of the rv042.
All data is on Vlan172 ....  Voice is on Vlan272
Main Work Router is a 3620, it has a route in it for the home network. i.e.  ip route 192.168.1.0 255.255.255.0 172.16.1.73
I can access the Call Manager Administration website from home with no problem.

I greatly appreciate any help.  Thanks in advance!

The problem was also occuring with my IP Communicator Softphone.

I was able to add the route to my call manager's gateway/router and everything is now working.

Thanks!
