Re: CM4.1 and remote site: vpn needed

nguyen · ‎04-12-2006

Hi,

I have CM4.1 on the main site behind a PIX.

For the remotes sites, I have 12 users on 1 and isolated users elsewhere.

Do I really need a VPN ?

Can a 26XX router with MGCP act as a gateway for the 12 users? if yes can I do that without a VPN?

if yes, should I open ports on the PIX?

is this unsecure?

what are the minimum requirements for the 26XX ? just MGCP? IPVOICE?

Thanks

I assume that your remote do not have private Point-to-point back to Main Site. So bascially, you have T1 internet, cable or DSL at remote site.

My suggestion is:

1. Have POTS (order from carrier, e.g. verizon) at remote site for 911 call.

2. I personally prefer H.323 over MGCP.

3. you need PVDM2, VIC2-2FXO(there are 2 port, 4 ports option that you can pick)

4. Inline power switch (external or internal (Etherswitch at router)).

5. IP Phones for all users.

6. Yes, you need configure IPSEC Tunnel (VPN) between router and PIX.

Please rate this post if it helps.
