Fail routing call from one gateway to other gateway.

Hi, I got problem with my as5300. I have 2 as5300.

Gateway A using private ip and Gateway B using public ip. I can ping from Gateway A to B and Gateway B to A. But I can route a call from Gateway A to B or from Gateway B to A. I have checked dial-peer configuration and I sure the configuration is right, because this configuration work at gateway that used private ip. Please somebody help me. Thank you.

Re: Fail routing call from one gateway to other gateway.

Since you're mixing public and private addressing, NAT is going to have to occur somewhere, and it's never pretty with IP Telephony. Remember that the Call Manager is only sending call setup messages between the two devices--and it has to be able to reach the private one, too. Once the call is setup, the two devices send RTP streams at each other, and if the public vs. private issue isn't addressed, the call won't be successful.

Can you give me solution for this problem ? What I need to do? Can I use NAT for this case ? Thank you for your respond.
