[Asterisk-Users] Asterisk over WAN

[Anderson Levi]

Hi  all,

I'm new to Asterisk and I was wondering if the following setup can work. 
If it can how would I go about setting it up:

   Phone------PBX------Asterisk Server------Cisco Router 
                                                                    |
                                                                    | WAN
                                                                    |
   Phone------PBX------Asterisk Server------Cisco Router

Any help would be appreciated.

Thanks.
