Cisco 1751v with two FXS port.

I need to move my voice gateway with an analog phone behind a PAT device that allows only port redirection.

I'm looking for help because now I'm not able to make an in or outbound call.

I believe I have a problem with NAT.

Hi Andrea,

You will need to make sure that your PAT device supports fixup for the protocol you're using. If you're using H323, make sure it is H323-aware, or if you're using SIP, make sure it's SIP-aware. Also know that there are different versions of H323, and the gateway should use version 4 if you're on a more recent IOS.

We have some features that allow for the gateway to get around non-aware devices, but it is only available on the 5x00 boxes.

hth,

Hi Nick and thanks for your help.

My PAT device doesn't support fixup for SIP.

Happy new year!

There is a way to configure STUN on my 1751v?

Thanks.
