[cisco-voip] ATA behind a firewall

[Diego Costa]

Hello guys,

    I want to try cisco ATA behind a NAT, I can use SIP and H323 also, I've
read some about STUN but in the documentation of the STUN servers that I
review, said that they don't work with Cisco ATA's.


The scenario would be:

 ------------                     --------------                        ----
---
| Gatekeeper |----Public IP's----| NAT FIREWALL |----Private IP's----> |
ATA-1 |
 ------------                     --------------                        ----
---

I would appreciate any help or suggestion.

Thanks
Diego.
