New to VoIP, need some pointers

[Reprovoid]

Hi.I'm curious how an IP phone can call another VoIP phone In a remote network.Do you use a combination of Directory/IP address.I don't even know If thats possible.

  If It's not , would I have to create a site-to-site VPN In order for the phones to communicate with their local Directory Nos?

I know how to configure the VPN and to connect the IP phones to a router using the CCA or CCP , give them DHCP etc but I have no practical experience when It comes to VoIP.

I've been reading about configuring VoIP dial peers.Would that be the best solution as opposed to a site-to-site vpn.

The IP phones know what to do because the IP PBX tells them.

Second question, you need them both. VPN to make the IP connectivity, and dial-peer to make the call routing.

So I can't Just use the public IP address of the remote network and there Directory wildmask to connect to the phones?

Is this possible but not recommended for encryptions reasons ?

No, it's not possible. You must use an IP PBX to control phones.

I have a networking/pc repair Job.I Install cisco routers and switches In small offices and have setup site-to-site vpn's.Nothing complicated.

Now the manager has purchased a UC540W to connect IP phones to a network.The UC540 will connect to a VoIP gateway wan connection which allows calls to anywhere In the world.

Does the UC540W have the capability of receiving a unique no from the telephone service like an analog phone so that It can receive calls from any analog phone and not Just make calls to them.

  I have a PT file of the setup at the office.

  I wont bother you anymore with this , you've helped me enough already!

Sure, that is normally done.

To learn about the UC500 there is a dedicated forum in "small business voice", and of course, the product documentation.

Thanks for the nice rating and good luck!
