Off premise i2004

[leftbase2009]

Just set up the BCM. Things work great. We tried to remotely locate an i2004 at another locations. Used partial DHCP an the outside IP address for the BCM. Phone came up with the correct signaling, but no talk paths. Would appreciate any help.

You need to have the remote IP Phone able to use not just the signaling IP address/port but all voice IP addresses/ports. For an IP Phone to IP Phone call for example in which the voice passes directly between the two phones, they have to "see" each other for everything to work.

So I need a VPN for a remote phone to talk to the BCM 50. Does the i2004 supportr a vpn without a vpn router at the far end?

You would need a vpn router.

Ok, VPN router works as long as it is a GRE Tunnel. Of course more and more companies don't support GRE, they support IPSEC. It appears on IPSec the remote end can't be DHCP. Has anyone had more in depth knowledge of this?

Use Nortel BSR222 VPN routers. Relatively easy to set up and once working rarely fail.

Thanks. Must I have one at each end or will they talk to cisco? On the remote end can we be DHCP or must we be static?

I've never set one up with a Cisco myself but technically it should work, just don't even know where to start. I always set them up as branch office tunnels and turn on DHCP in the router. WHen you set up your ip phone, set it for partial DHCP and manually set your S1 server address and let the routers do their thing.

I've always had BSR's at both ends.

Good Luck though.
